What does a "reverse" dovetail do that a regular one doesn't?

It cuts an inverted dovetail into the top of stock as thin as 3/8" (9.5mm). MATCHFIT clamp heads drop into that groove and sit below the surface — so you can hold thin templates and parts that a standard dovetail's 3/4" material requirement would rule out.

How thin can my templates be?

3/8" — half the thickness a standard dovetail bit needs. Thinner templates are easier to make and easier to handle, and the clamping holds whether you're pattern-routing top-down or flipped over with a hand router.

Won't the clamps get in the way of my router?

No — that's the whole trick. The clamp heads sit completely below the surface, so flush-trim bits, hand routers, and sanders glide right over the top. Nothing to steer around, nothing to hit.

Can I clamp work to my bench with it?

Yes. Cut a groove across the top of any board and you can clamp that board to a table, countertop, or sawhorse — no dovetail on the underside, no stepping up to thicker material. It holds for chiseling, routing, sanding, whatever the job is.

Does it work on acrylic or polycarbonate templates?

Yes — Acrylic and Polycarbonate will both work, even as thin as 3/8" (9.5mm). At 3/8", the bit will cut through, just use stopped cuts.

Is it CNC-friendly?

Very. Cut the template shape and its grooves in the same CNC session. No CNC? Set your router table fence and make each groove in one straight pass.

Router table or handheld?

Both. It cuts at the same 3/8" depth as the standard MATCHFIT dovetail bit, and the same setup gauge dials it in either way.

Can it do joinery, or just workholding?

Workholding is the day job — joinery is the bonus. Mate mirrored cuts with this bit to get sliding joints for drawers, trays and support slides. Three cuts, two parts, one bit.

Do I need MATCHFIT clamps?

The groove is cut to the MATCHFIT system's 14° geometry, so MATCHFIT dovetail clamps drop straight in — and everything it cuts plays with the dovetail grooves you're already routing.

What makes a glue joint bit "reversible"?

One bit, one setup, both halves of the joint. Cut the first board, flip the mating board, and cut again — the symmetric wave profile nests the two together perfectly, with no second bit and no second setup to drift.

How does the wave keep my glue-up aligned?

The interlocking profile registers the boards to each other, so parts can't slide out of line under clamping pressure. Cutting boards, doors, stair parts, wide panels — they clamp up flush and stay that way.

What does the FitFinder Center Platform actually do?

It's the patented reference machined into the bit that pairs with the FitFinder 1/2 Gauge to center the profile on your stock — the right setup the first time, instead of a scrap pile of test joints.

What stock thickness does it handle?

From 1/4" (6mm) up to 1-1/4" (32mm) thick.

Is it actually stronger than a plain glue-up?

The wave gives you 60% more glue surface than a butt joint — and a better-looking joint line than tongue and groove, with a wave that shows off at the ends of your glue-ups.

How much material do I lose per joint?

Just 0.100" (2.5mm) — versus the typical 3/16" to 1/4" other glue joints eat. Across a wide panel, that's real wood saved.

Which size do I need?

Two ways to buy it: the large bit has the Fence Boss — a positioning surface milled into the bit body that sets your router table fence fast and accurately — while the 3/4" bit carries a sealed bearing that takes the wave joint onto curved parts. Available in 1/2" and 1/4" shanks.

Can it do more than glue joints?

Yes — run it as a decorative edge profile, or cut wave surfaces for creative work. The joint is the day job; the profile is the play.

Will it fit my router table?

If your table has a standard 11-3/4" × 9-1/4" plate opening, yes — commercial or shop-built. The machined-aluminum insert plate includes leveling screws to sit dead flush with your table.

Does it do everything a normal router lift does?

Yes. The OFL3.0 performs every function of a standard premium lift — fast, accurate height adjustment with secure locking and 3.94" (100mm) of travel. Then it does the thing no standard lift can: pivot the bit up to 50°.

Is a router motor included?

Yes. The lift comes as a complete system — a 2 HP variable-speed router motor running 3,500 to 30,000 RPM, with 1/4" and 1/2" collets and the wrenches to use them.

How do I set an angle?

Snap-in presets lock in the angles you use most — 15°, 22.5°, 30°, and 45°. For everything else across the –5° to +50° range, the vernier scale dials in any angle quickly and accurately.

How do bit changes work when the lift is tilted?

The lift travels forward and back to keep the bit centered in the throat opening at any angle, so bit changes and adjustments stay just as easy as on a standard lift. Every adjustment — tilt, travel, height — is 100% tool-free.

Do I need special bits?

No — that's the point. Tilting multiplies the bits you already own: straight bits cut chamfers and angled grooves, profile bits produce new shapes at every angle, and slot cutters make spline joints at the exact angle of your work.

What are the three throat plates for?

They're magnetic, and they keep the opening matched to the work — swap between straight and tilted operations in seconds. Set flat with the lift, they turn your table into a true precision milling surface.

What about dust collection?

The under-mounted dust shield beneath the lift, along with the dust post on the Mast-R-Fence, combine to capture dust at the source.

Why is this only available from MicroJig?

MicroJig is the exclusive US distributor of Sauter's pivoting router lift — precision German engineering, available in the US only at microjig.com and through this page.

What's actually in the box?

The complete router table setup system: the FitFinder and its Upgrade Kit, the all-new Fence Boss system — adjustable magnetic stands plus the custom steel rule — and both Wave Reversible Glue Joint Bits, in 1/2" and 1/4" shank. Every piece is French-fitted into an EVA foam insert in the custom case, stored securely so you always know where your parts are.

What does the FitFinder set?

Bit height, any way you work. Set to the halfway point of your stock, transfer a measurement from another machine, or take one from a tool — whatever the reference, the FitFinder makes the height easy to hit.

What is the Fence Boss system?

The fence half of setup. Adjustable magnetic stands hold the steel rule at exactly the right height while you bring the fence in — set to the bearing of your bit or to any particular spot on the cutting edge. Works perfectly every time.

What else does the steel rule do?

Two more jobs: it zeros bits to your router table fence, making adjustments to specific dimensions easier, and it's designed to lay out the mounting hole locations for ZeroPlay Miter Bars.

Are both Wave bits really included?

Yes — the full pair. The 1/2" shank version cuts stock up to 1-1/4" thick and carries a machined top section for setting your fence with the Fence Boss. The 1/4" shank version cuts stock up to 3/4" thick and carries a top bearing for template work, curved parts, and shaped pieces.

What's the Center Platform for?

It's the patented reference machined into both Wave bits that pairs with your FitFinder — set the bit height right the first time instead of sneaking up on it with test cuts.

What's a reversible glue joint?

One bit, one setup, both halves. Cut the first board, flip the mating board, cut again — the wave profile joins them with more glue surface and self-aligning registration, so your glue-ups clamp flat and stay flat, with an elegant wave visible on the ends of cutting boards, trays, and presentation pieces.

Why does my GRR-RIPPER need a cleaning station?

Because grip is the whole job. Sawdust brushes off, but wax from your tabletop and resin from your wood slowly embed microscopic dust into the Green Grip — that's the black buildup — and a slick GRR-RIPPER is a GRR-RIPPER that slips. Clean grip is safe grip.

How do I use it?

Two ways. Dry, for everyday cleanup: sweep your GRR-RIPPER across the pad one-handed while you work, and knock the ReNew clean when you're done. Wet, for deep cleaning: add a little alcohol to the pad, make a couple of passes, wipe the Green Grip with a clean cloth — buildup lifts away and the grip comes back to like-new.

What kind of alcohol?

Denatured alcohol or rubbing (isopropyl) alcohol — the same cleaners recommended for Green Grip material all along. A little on the pad is all it takes.

Which GRR-RIPPERs does it work with?

All of them. If it wears the Green Grip — AIR generation, current models, or the legacy GRR-RIPPERs you've had for years — the ReNew cleans it.

Will it fit my saw?

The front legs are designed to drop into the gap between the fence rail and the table on most cabinet saws, and two set screws in the front leg fine-tune the fit to your saw's exact gap — so it lives right where you use your GRR-RIPPERs.

What if my saw doesn't have that rail gap?

Use the notch. The bottom of the front leg fits the standard MATCHFIT Dovetail Groove, so you can mount the ReNew on a dovetailed worktop, or rout a quick plate to clamp it to a jobsite saw — anywhere in your shop.

Do I have to remove it to work?

No — that's the point of the mount. It sits at the saw, out of the cut path, ready for a one-handed pass between cuts.

Is the cleaning pad replaceable?

Yes. Pop the retaining plates off each end and swap in a fresh pad in seconds — the station lasts, only the pad renews.

Can it clean anything besides GRR-RIPPERs?

It moonlights nicely. Light rust on a chisel, dried glue on a screwdriver, residue on hand tools — the pad handles light restoration jobs right at the saw.

How often should I clean?

Make the dry pass part of normal use, whenever chips collect. Go wet when the Green Grip starts to darken or feels slick — don't wait until it's fully black.

How do bit changes work when the lift is tilted?

The lift travels forward and back to keep the bit centered in the throat opening at any angle, so bit changes and adjustments stay just as easy as on a standard lift. Tilt and travel setups are tool-free.

  • GRR-Ripper

    What if the Riser lifts my GRR-RIPPER above the Rip Fence?

    The GRR-RIPPER always needs to guide along the rip fence at the table saw. An auxiliary tall fence like our 3-In-1 Jig can be used to extend the rip fence height.

    Can I use the ReSaw Riser with the blade guard on my table saw?

    The GRR-RIPPER passes over the blade so there can’t be anything in the way. Don’t worry, the GRR-RIPPER is your moving blade guard.

    Does the ReSaw Riser work on my other machines?

    Yes, you can use the ReSaw Riser Blocks at the router table as well as the Table Saw. Just be sure to use an auxiliary tall fence as needed.

    Why plastic?

    All GRR-RIPPER accessories are made of specially formulated high-impact plastics for good reason. It maintains its shape and rigidity, but also absorbs force if it makes contact with the blade. In other words, it won’t shatter or break your wrist.

    Will it work with my GRR-RIPPER accessories?

    The scale on the SafeRip Kit is designed to ONLY be used with the 1/4” or 1/2" leg of the GRR-RIPPER against the rip fence of your table saw. It SHOULD NOT be used when the 1/8” leg, Adjustable Spacer, Balance Support or any shop-built feature is against the rip fence.

    The SafeRip kit is fully compatible with the Stabilizing Plate, Gravity Heel, and Handle Bridge Kit.

    How does the SafeRip cursor work?

    Once your rip fence is set to the desired cut, simply adjust the Center Leg of your GRR-RIPPER so that the measurement you are cutting is NOT underneath the orange cursor on the GRR-RIPPER that is facing you.

    For example, if your rip fence is set to 1-1/8” (29mm), the 1-1/8” (29mm) mark on the back of the GRR-RIPPER should be to the right of the orange cursor.

    The cursor automatically accounts for the blade width and works on both side of the Center Leg, so when making a 2-1/2” (64mm) rip cut, the 2-1/2” (64mm) mark should be to the left of the orange cursor and the blade will pass safely to the left of the Center Leg.

    What is the difference between the GR-100 and the GR-100+?

    The GRR-100 plus comes with our SafeRip system that helps prevent accidentally cutting into your GRR-RIPPER’s Center Leg. Your GR-100+ includes two measuring stickers that you apply to the assembled GRR-RIPPER, and two transparent orange cursors that move with the Center Leg as you adjust it.

    What are the Dovetail Grooves for?

    You can use these Dovetail Grooves to create and attach you own shop-made accessories with the MatchFit Dovetail Hardware. Building a sacrificial heel and attaching it to the back of the Grr-ripper2 Go is a great option.

    Does Grr-ripper 2GO work with any of the Grr-ripper accessories?

    No. The Grr-ripper system accessories do not work with the Grr-ripper 2GO. However, you can use the MatchFit Dovetail Hardware to slide into the dovetail grooves and make a sacrificial heel.

    Is the GRR-RIPPER OSHA compliant?

    Yes. OSHA regulations state that “...​in a workplace, regulations require that unsafe saws be removed from service immediately, push sticks or push blocks be provided at the work place for guiding or pushing material past the blade, and emphasis be placed on the cleanliness around woodworking machinery and, in particular, the effective functioning of guards and prevention of fire hazards. 29 CFR1910.213(s)

    Where can I buy the GRR-RIPPER in Australia?

    I have missing parts for my GRR-RIPPER, what do I do?

    We’re so sorry about that. Please call 1-855-RIP-SAFE (747-7233) or contact us here with the missing parts and the quantity you need.

    How do I use the GRAK-404 Upgrade Kit for the GRR-RIPPER?

    Here’s a short video showing many of the great uses for the GRAK-404 Upgrade Kit AKA the Stabilizing Plate and Adjustable Spacer.

    Why would I need two GRR-RIPPERs?

    We recommend using two GRR-RIPPERs when cutting stock longer than your table saw top.  In order for the GRR-RIPPER to work properly, it needs to be on top of the material, with the material on the table top.  If you stop feeding material to reposition your GRR-RIPPER, the saw blade will leave blade marks and burning. With two GRR-RIPPERs, you can feed stock continuously using the hand-over-hand method, resulting in better cut quality.

    Can I use the GRR-RIPPER with the blade guard on my table saw?

    The GRR-RIPPER passes over the blade so there can’t be anything in the way. Don’t worry, the GRR-RIPPER is your moving blade guard.

    Will the GRR-RIPPER work on my table saw?

    It will work on any standard table saw with a fence and a blade.

    My GRR-RIPPER doesn’t seem as grippy as it used to - what gives?

    Over time, dust and other contaminants can build up and compromise the effectiveness of the Green GRR-RIP material. Cleaning the gripping surface with denatured alcohol should restore your GRR-RIPPER to its original glorious grippy-ness. In rare cases, prolonged exposure to sunlight can damage the gripping material, so keep it out of direct sunlight.

    Will the GRR-RIPPER trip the sensor on my Sawstop?

    No. The plastic material will not trigger the safety mechanism on Sawstop saws.

    I cut into my GRR-RIPPER now what?

    Every part of the GRR-RIPPER is individually replaceable, and compatible with all GRR-RIPPER models. Browse and swap out any damaged part with a replacement.

    Why plastic?

    The GRR-RIPPER is made of specially formulated high-impact plastics for good reason. It maintains its shape and rigidity, but also absorbs force if it makes contact with the blade. In other words, it won’t shatter or break your wrist.

    MatchfIt

    What Routers will this work with?

    It will work with any router of 1 to 3 horsepower. You just need to have an adapter base that takes the Porter-Cable style guide bushings. You do not need a guide bushing, just a bushing adapter sub-base on your router. 

    The PC style guide bushing is the industry standard and most manufacturers make a base so these bushings can be used with their routers. There are also many "universal" bases made that will allow a range of routers to use the guide bushings.

    Our base has a molded ring in the top that is the same size as a PC guide bushing. This ring locates the bit and keeps the router in place. Our universal clamps hold the router on the ring while allowing you to rotate it so your router controls are accessible. The base, in effect IS the "guide bushing" controlling your router as it cuts the dovetail grooves.

    Universal Guide Bushing Bases

    NOTE: If using one of these bases, use should remove the spring and shoulder washer from the T-bolts.

    What are the recommended wood type for MatchFit Dovetail Tracks?

    3/4" or thicker: Void-free quality plywood (11-ply or more, Baltic birch is best), standard MDF or seasoned hardwood.

    Which brands of track saw guide rail do our clamps fit with? Works with any standard 12mm x 8mm T-slot.

    The MatchFit Dovetail Ratchet Clamp AP not only works with MatchFit Dovetail Tracks but also any standard 12mm x 8mm T-slot/T-track. Does not work with DeWalt track saw guide rails.

    Which brands of track saw guide rail do our clamps fit with?

    Our DVC700 Ratchet Clamp is the only one that is designed to fit into guide rails for saws.

    It fits all the major brands that other aftermarket track clamps fit, but unlike other clamps, ours has the AP Spring that keeps the clamp arm where you set it during use.

    Not compatible with Festool tracks or DeWalt track saw guide rails.

    Can I use MDF for Matchfit tables and jigs?

    Good quality plywood or MDF work just fine for the MatchFit Dovetail System. Because the clamp pressure is normally directly over the clamp head in the groove, the groove is supported and the board does not tear out. There is a video showing the process here: https://youtu.be/oHtOey0-97U

    Why is the Dovetail Hardware getting stuck?

    When you tighten the Dovetail Hardware into a plywood or MDF groove, the 14 degree dovetail profile wedges the plastic head of the hardware in place in the groove.

    This "locks" the hardware in place so it cannot move side to side within the dovetail groove. So you can wedge a Track Screw in place, loosen the knob, and turn a cam clamp to secure stock in ways that T-Track hardware cannot.

    When you are done, just press the Track Screw or Track Nut back down into the groove to 'snap' it loose and slide it to your next task.

    How do I open the router bit case?
    step 1 - cut around the label
    STEP 1

    Cut the label around the entire case (360º).

    step 2 - hold bottom and twist
    STEP 2

    Hold the bottom and twist the top counter-clockwise.

    step 3 - lift the case off
    STEP 3

    Lift the top off and pull the router bit up and out.

    How wide of a dado can I cut with the Dado Stop?

    The dado Stop can cut dados from 1/8" up to 15/16" wide with a full kerf blade, and up to 1-5/8" using a stacked dado blade set.

    How long of a dado can I cut with the Dado Stop?

    It depends on the saw.  The Dado Stop is designed to make crosscut dados using a miter gauge.  You must be able to register off of Leg 3 with your miter gauge in the miter slot, and without your workpiece in front of the blade without touching it.

    Will MATCHFIT Dovetail Clamps and Dovetail Hardware fit into my Festool track?

    The clamps will not, the hardware will, but that’s kind of missing the point.  The MATCHFIT system was designed to be compatible with a standard router bit profile, so that users wouldn’t actually need metal tracks.  However, some users have been known to file or grind about .005” off of the wide part of the clamp’s elbow and use them in their Festool track.  Our advice is to use Festool clamps with Festool tracks, and use Dovetail Clamps for everything else.

    Why dovetail tracks as opposed to T-slot?

    When tightening anything inside of a t-slot, the pressure is applied perpendicular to the material surface, which may weaken the integrity of the track.  If a t-slot is cut into plywood, all of the force is concentrated on the small flange at the bottom, causing the plywood to delaminate. With a dovetail profile, the clamping force is distributed evenly along the entire wall of the track for an overall strong hold.

    Do I need the MATCHFIT Dovetail Router Bit in order to use Dovetail Clamps and Dovetail Hardware?

    Only if you value your time.  Standard dovetail router bits cut to a sharp point at the top of the groove, which requires a decent amount of sanding after the track is routed.  Our router bit incorporates a 1/16” roundover to automatically smooth out the top of the track in a single pass.  Less time sanding means more time building.

    Can’t I just do the same thing with dog holes?

    Not really.  Dog holes only allow clamps to go through the material with the head sticking out of the bottom.  Dog holes confine clamps to fixed locations, which aren’t always where you need them.  Dovetail Clamps can be positioned anywhere in a dovetail track, inside the material and out of the way.

    How are these clamps different from other F-style clamps?

    They’re track clamps. The head of the MATCHFIT Dovetail Clamps are forged into a dovetail shape, compatible with any standard ½”–14º dovetail router bit. It moves through the track created by a router bit instead of an expensive metal t-track.

    ZeroPlay

    Will ZEROPLAY Miter Bars fit my saw?

    ZEROPLAY Miter Bars will fit ANY standard (3/4” x 3/8”) T-Track miter slot that measures between 0.73" and 0.79" wide and at least 5/16" deep.

    Compatible miter tracks include but not exclusive to ShopSmith, SawStop, Bosch 4100, Delta Unisaw, Powermatic, Rigid, Dewalt, and General 350 Tracks.

    *Not compatible with table saws with 'Tabs' cast into the top of the miter slot or 5/8" miter slots i.e. Ryobi or Craftsman.

    My table saw has tabs at the top of the miter slot. Will ZEROPLAY Miter Bars work on my saw?

    No. The tabs will get in the way.  Refer to the compatibility diagram here:

    I’m having trouble adjusting my miter bars - either too tight or too loose. Any tips?

    If your miter bar fits well but becomes too tight when installed on a sled, you may have tightened the panhead screws too much. Overtightening those screws can cause the bars to compress and expand outward.  Try putting a single strip of paper on the inside of one of the miter slots when adjusting the miter bars’ width.  This should offset the compression that occurs during installation.

    Does the ZEROPLAY 360 Sled Kit include the sled?

    No.  The kit is designed to allow users to build their own sled, to their own specifications.  Don’t worry, you can do it!  We provide detailed, easy-to-follow instructions for building the sled of your dreams.  Believe in yourself.

    Do the ZEROPLAY 360 Sled Kit or single miter bar kit include the ZEROPLAY Miter Stop?

    No.  The Miter Stop is included with the double miter bar pack, and is also available individually.

    Does the ZEROPLAY Miter Bar work with Shopsmith® miter tracks?

    It depends. The miter slots vary in width from model to model. Measure your miter slot to ensure that it is at least .730" wide"

    Grr-rip Block

    I accidentally cut the Smart Hooks off - what now?

    What is the difference between the GRR-RIP BLOCK and the GRR-RIPPER?

    The GRR-RIPPER is designed for adjustability, whereas the GRR-RIP BLOCK was designed for simplicity, and pure traction.  They feature the same GREEN GRR-RIP material, but the GRR-RIP BLOCK has a solid,  much broader gripping surface and auto-retracting Smart Hooks.  It’s ideal for use on the jointer, the router table, and on the bandsaw.  It can be used on the table saw, but only for non-thru cuts or cuts that don’t require passing directly over the blade.

    MICRODial

    On what tools can I use the MICRODIAL??

    The MICRODIAL is most commonly used on the table saw, but it can also be used on the router table and the bandsaw, if you have a fence on the right side of the blade.  For more information about how to use the MICRODIAL, please refer to the instruction manual.

    Do I need a GRR-RIPPER in order to use the MICRODIAL?

    The MICRODIAL was designed to work with the GRR-RIPPER, but it depends on the cut.  To cut tapers on wide panels, you can help feed the material with your other hand, provided it’s no less than 12” from the blade.  To cut tapers on small or narrow stock, we strongly recommend using GRR-RIPPER(s) to safely feed material through the cut.  This is not only safer, but will give you better results.

    What is the maximum length I can cut?

    It depends on the saw.  The MICRODIAL cuts tapers by running along the fence. It must have enough of its edge in contact with the fence to remain straight from the start of the cut, with the Heel Hook at the tail end of your workpiece, and with your workpiece in front of the blade without touching it.

    MJ SplItter

    How much space behind the blade do I need?
    My zero clearance insert is phenolic. Can I still install SPLITTERs?

    Yes! However, the installation process is slightly different to account for the density of the material. Watch this video to see how SPLITTERs are installed on a phenolic zero-clearance insert.

    Will the MJ SPLITTERs fit on my zero-clearance insert?

    With the blade at maximum height, you need a minimum of 2” behind the blade to install the SPLITTERs.

    Can I get replacement inserts for my MJ SPLITTER or MJ SPLITTER SteelPro without buying the whole kit?

    MJ SPLITTER replacement inserts are only available from MICROJIG – they cannot be found in retailers. Shop Now

    Will the MJ SPLITTER SteelPro fit in the original MJ SPLITTER holes I've drilled?

    No, it won’t. The SteelPro needs its own separate drilling guide and its spacing is different than the original MJ SPLITTER.

    Does the MJ SPLITTER system work with 12" Saw blades?

    Yes, please download and read the instructions.

    BladeMatch

    What if I get my blade(s) sharpened?

    Sharpening a saw blade will certainly affect the kerf it cuts.  Adding Arbor Shims to offset the difference will ensure accuracy of the fence scale and mitigate the dangers associated with a misaligned riving knife.

    It’s such a small difference, does it really matter?

    When talking about thousandths of inches, the problem can appear negligible.  However, in terms of joinery, .010” may as well be the Grand Canyon.

    What do they do?

    Changing from a full kerf blade to a thin kerf blade effectively changes the distance between the blade and the fence, resulting in a misaligned riving knife, and an inaccurate fence scale.  BLADEMATCH Arbor Shims allow you to maintain a constant cut line, regardless of the blade’s kerf width.  This keeps your fence scale reliable, and your riving knife in proper alignment.

    Do I really need Arbor Shims?

    If you use one saw blade for every cut, no.  If you use a variety of blades for different types of cuts, absolutely.
