SteelPro splitters greatly reduce the chance of kickback and virtually eliminate binding and burning.

WATCH VIDEO >

Use offset splitters to virtually eliminate kickback, binding, and burning.

Get precise and virtually burn-free results with the MJ SPLITTER’s mini featherboard effect. Works while cutting materials such as MDF and plywood. Each side of the splitter is offset by several thousandths of an inch, giving you the the right amount of tolerance and pressure for your cut. Flip the splitter around so the + marking faces the fence to get the correct offset. Each + marking represents 0.003″, so +++ equals 0.009″. Precision and safety does come in small packages.

MJ Splitter

Foolproof installation into your Zero Clearance insert (ZCI).

The precision drill guide aligns your drill perpendicular to the table saw surface so you can drill straight into your ZCI. It’s design directly lines up the splitter to your ZCI for accurate alignment with the blade. Installation is so simple, it’s foolproof.

MJ SPLITTER SteelPro products are available in Thin Kerf (Orange) and Full Kerf (Blue).

Our toughest splitter ever. Work safer. Work smarter.

The MJ SPLITTER SteelPro has an ABS polymer shell reinforced with a solid stainless steel core. It’s able to take on the stress caused by many solid woods, greatly reduce the chance of kickback on your table saw, and virtually eliminate burning.

Our toughest splitter ever, utilizes the same patented technology of our original MJ SPLITTERs.

MJ Splitter

Keeps your keeper piece square against the fence and automatically keeps your kerf.

The Automatic Kerf Keeper prevents the saw blade and splitter from binding while cutting hardwoods. When tension and pressure build, the Kerf Keeper is pulled out automatically by the closing kerf. The Kerf Keeper travels with the pinching kerf, and keeps it open reducing stress on the saw blade and splitter.

When you see the Kerf Keeper deploy, that’s your sign to turn off the table saw. Be alert. Be safe.

Marc says, “In my opinion, the simplest and most inexpensive solution is MicroJig’s MJ Splitter SteelPRO. The beauty of this system is that it works on just about any tablesaw, regardless of age or quality level.”

From DIYers to professionals alike, the MJ SPLITTER is the smart choice for safety. See for yourself...

Excellent product

Being disappointed by another product that I bought to use for a riving knife , I have been looking around for another product which would give the protection/safety that I desire when using my Unisaw. Last week I found the Micro Jig MJ Splitter Steel PRO System w/Double Splitters and after watching the videos on YouTube I ordered one on Amazon for $25.00. I received it yesterday and I installed it this morning. On the videos the installation seems a little bit confusing and complex but in fact by following the step by step, it is very easy, simple and quick. This morning I ran a few board of white oak and of poplar through the saw and I am very impressed by this simple but effective product. I especially like the mini-feather board effect which keeps the piece being cut tight against the fence. My only concern now is to not loose the splitters, they are small and it would be very easy the sweep them away with the saw dust. I have used this product now for about two weeks. It works extremely well for me especially considering its very low price compared with some much more expensive products around which do not work this well. I now give this product 5 stars as it really exceeds my expectation.

Another great product from Micro Jig!

What a wonderful product! Really well made and high quality. I have a stock riving knife which came with my table saw, but it was designed for 1/8 full kerf blade. When I put on my newly acquired 0.91 thin kerf rip cut blade, the stock riving knife was too thick for this new baby. After having purchased and installed MJ splitter, I am very happy because I can now use this thin kerf blade to rip all kinds of lumber safely. It works perfectly with a zero clearance insert (ZCI) dedicated to this new blade. BTW, my new thin kerf blade cuts much better than my old full kerf blade. I also love the mini feather board feature of MJ splitter. Properly installed, the double splitters would push wood pieces slightly away from the blade after cutting, making safer and more accurate cut. I am thinking about buying another set of MJ splitters (1/8 kerf version) to replace the stock riving knife for my full kerf cross cut blade (even though I will have to buy another new ZCI), because I think MJ splitters works better than riving knifes. I personally know how scary and dangerous it could be when kick back happens on a table saw. Splitters (or riving knifes) is the single most important safety caution you can take to prevent kick backs. BTW, for those who considers this product but have read about complaints of having difficulty drilling into plastic ZCI, make sure you use a 3/16 plastic drill bit to drill into plastic ZCI, instead of the general purpose drill bit comes with the package (which is good to drill into wood insert). You need to make sure the holes to be clean and tight. A $5 3/16 plastic drill bit is critical for a proper installation of MJ splitters, if you plan to use a plastic ZCI. I think MJ splitter should be installed on every woodworker's table saw. Highly recommended!!

Useful device

Having personal experience with a finger injury on the table saw, I was looking for accessories that would make the process safer. I put this splitter on my saw several months ago, and have found it to be very helpful. What I especially like is that it not only acts as a splitter to prevent blade binding, but also as an after-blade feather board, pushing the piece against the fence, allowing more accurate, straighter cuts, reducing saw marks and kick-back pressure, and adding a dimension of control you don't get when doing it by hand. Using it with a pre-cut feather board is optimal. It makes me feel much safer because I don't have to get my hands close to the blade. This feature alone makes it well worth the cost. The set comes with extra splitter pieces for various depths of cut, and they also offer additional sets for various blade thicknesses, so you may need to acquire additional zero-clearance inserts to accommodate the different options and to allow quick change. It is a little technical/time consuming to install, but the provided instructions are very specific, and done right, it is very effective. If it helps save your fingers, my review time will have been well worth it.

This item is awesome, coupled with a new saw blade it helps to make some of the cleanest cuts ever. Some UV protection would be a welcome upgrade as my previous MJ Steel Pro deteriorated and cracked with a little bit of sunlight. All in all a great addition to any saw bench.

This works great, I have an old saw with no guarding so this was exactly what I was looking for. Install wasn't too bad. My throat insert could only accommodate one splitter so I can't comment on the other piece.

Nice Table Saw Upgrade

Instructions were thorough and well written. Installation took about an hour with the creation of the necessary zero clearance insert. The ability to customize the splitters to the exact needed dimensions was very helpful. I have used the saw with the splitter installed building kitchen cabinets and I have given it a very fair test. I would highly recommend this product if your saw doesn't have a top quality splitter or riving knife. The splitter my saw was shipped with was (in my opinion) actually a safety hazard and it ended up in the trash. The Micro Jig has made ripping and cross cutting sheet goods much more comfortable. The splitter keeps the stock held firmly against the rip fence without binding. I have also seen the same when ripping solid stock. This simple device offers real value considering it's cost.

Critical piece of table-saw safety

I already had a standard-kerf MJ splitter, so this went into a new insert with a new thin-kerf blade. It works flawlessly. I used the standard double-splitter installation (not the kerf keeper) and sometimes have to remove the second splitter to avoid binding. I've even used this when resawing reclaimed lumber and gotten outstanding results with no kickbacks (knock on wood!). Overall, this does what it's intended to do - which is prevent material from contacting the rear of the blade - and does it well. Combined with my aftermarket fence and anti-kickback rollers and/or pushsticks, this allows me to safely and consistently make super-clean cuts.

This Kit Does Work Well

I installed the Steel Pro (Orange) Kit this morning. As others have said, read the instructions carefully and follow them. I read them over several times until I had a clear picture in my mind how to install them and why they need to be done in just a certain way. A couple of observations - I use a Lee Craft zero insert, which a couple of other people here had some difficulty with due to its extreme hardness. Use a high quality sharp bit. I used a brand new brad point bit. And, it still took a lot of force to drill the holes. If there is not enough space between the rear of the blade and the edge of the insert then lower your blade to 2.5 inches or 2.0 inches high and that may give you the room for two inserts. If not, just use the one - it will still work. I have a DeWalt E748 and was able to keep my Forrest blade stabilizer by setting the blade to the 2.5 inch mark and that left room for two inserts easily. If I need to rip something higher than 2.5 inches I will simply put my DeWalt insert back in. I use the saw for furniture and I have never needed to rip anything higher than probably 2 inches. I opted for the splitter and the kerf keeper setup as I decided to have the extra measure of safety the kerf keeper allows. Be sure the wood platform is really clamped down onto the saw when you are ready to drill your holes. Mine platform (setup board) slipped when I started on my second set of holes and I had to realign by inserting a bit into one of the first set of holes and re-clamping. Fortunately, there was no harm done. And lastly, GO SLOW. I am looking at these two little things sticking out of my insert and I am thinking, "Wow, I paid forty dollars for those little gizmos?" Well, if I had a kickback and I was in the way it would be worth it. I'm 75 and not nearly as nimble as you youngsters that can hop out the way (maybe). Kirby

Great Little Device

I just installed this device into a zero-clearance insert on my Jet hybrid saw. The saw was designed before riving knives were standard equipment on table saws. I wanted the safety of a splitter that was unobtrusive, not at all like my factory splitter/guard. With a device like that, I knew I would be more likely to use it as compared to the factory unit. The MJ splitter turns out to be all that and more. Here are a few points and comments based on my experiences this evening installing and using the splitter: Concept: The MJ Splitter is a simple, easy to snap in & out, sturdy device that installs into a ZCI on your table saw. It has multiple configurations. It can be set up to simply maintain a kerf, or to apply a very small force to one or both sides of a kerf. Its purpose is to enhance safety and increase accuracy without being obtrusive. Construction: The splitter has a stainless steel core surrounded by a slippery plastic. Inatallation: Requires care. Follow the instructions exactly. I might quibble some with the authors of the installation instructions concerning the wording and layout. There are several splitter configuration options available. The info was there, but I thought it was a little difficult to decrypt. Nevertheless, I completed the installation in about 45 minutes with very satisfactory results. Setup: Easy to remove and install as circumstances dictate. Just pull it out of its mounting holes to remove it. Put it back in just as easily. Or just have two ZCIs - one with and one without the splitter. Adjustments are easy too: just replace the splitter with another of different offset (several are provided in 3/1000" increments. Limitation: Can only be used with blade at 90 degrees. It of course doesn't tilt with the blade. Using It: I performed lots of test rips tonight. The MJ Splitter worked beautifully. At no time did the board tend to creep away from the fence downstream of the blade. I felt that my safety and accuracy were enhanced. Conclusion: Great product. Works just like it is supposed too. UPDATE January 2014 - I'm happy to report that I still use this on my saw! It is unobtrusive enough to use in the vast majority of situations. Very pleased with the enhanced safety and accuracy. Recommended.

I learned a great deal immediately

Between all the available installation videos and the printed directions with illustrations, I was able to install this with no problems. I installed both the regular kerf model and the thin kerf model on separate ZCIs. I was able to test these as I had to mill about a dozen one by one inch strips of white oak, twenty four inches long from a wider, thicker board. The right side feather board effect is particularly interesting, I learned a great deal immediately. I was able to discover how inconsistently I have applied force with push sticks in the past. In addition to the expected safety, I definitely appreciated being able to find and correct my handling! Somewhere between 12 and 14 inches into a cut, my push stick force forward and slightly tilted towards the fence was at times causing some uncut section nearest to me to move away from the fence. Once I realized and corrected that, i found I could feed with almost totally consistent pressure throughout the cut. Incidentally, I found it much easier to feed a wider board than I ever have in the past, not sure why, but a very pleasant result. Overall, my only concern, at all, is how firm should the fence side splitter's feather board affect be? But after running 24 feet of material through, I do feel that whatever my personal settings, they added a huge margin of safety to my 3 HP Delta Arbor saw that I bought used, without a riving knife.

Work more safely.

I have a 10" Jet Table Saw, I only have 1" to the right of the blade, and 2" behind the blade at full cut capacity. My zero cut inserts are constructed from ½" oak laminated plywood, from any building center. There was no problem in mounting these splitters, not just one but both of them. They mount in line with the blade cut, with just 2" behind the blade cut, at full depth capacity, there was plenty of room to mount the two. I don't like the factory splitter, and a splitter needs to be used. These work out great, their small, inserted and are removed easily, however they can only be used when your blade is at 90 degrees,only, they do not tilt or bend. They are worth the money and I wish I saw these years ago. The size of the instruction sheet is a little over whelming, just keep in you mind what a splitter does. Installation was easy, it was a little time consuming, measure twice, drill once, you have one shot only to drill the mounting holes, other wise you need another zero cut insert. If you buy your zero cut inserts, ouch!

- Pete

Does what is claimed -- a good product

Really good product. Easy and pretty quick installation. But, a bit expensive considering just a few screws, drill bit and plastic. Still, a good safety addition to the shop.

Frequently Asked Questions

I drilled my holes for the MJ SPLITTER askew on my ZCI. What do I do?
We’re really sorry to hear this. This will specifically happen for LEECRAFT brand inserts because they are very high-density. That’s why we recommend using wood or UHMW-based throatplates for the MJ SPLITTER SteelPro. To save your ZCI, you can fill the holes with epoxy and re-drill again using these instructions: Because the density of LEECRAFT inserts is much higher than most inserts. Thus, to install our splitter into a LEECRAFT insert; first, follow the instructions. Then after drilling lift the drill bit out a little bit and use either pressured air or a vacuum to get rid of some of the wood dust. Please note, do not take your drill completely out of the hole because a 90-degree angle for drilling is a requirement. Repeat this step until the hole is drilled through. This again is only for LEECRAFT brand inserts; because the inserts have higher density the hole will take very long to drill all the way through. Thus, the drill bit and wood dust will create a lot of heat energy melting your drill guide. If there’s an issue with your replacement drill bit and drill guide, we’ll send you a new one. If your ZCI is beyond repair, please provide proof or purchase of your LEECRAFT ZCI and we will reimburse you. Please call 1-855-RIP-SAFE (747-7233).
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.

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