THE #1 AFTERMARKET SPLITTER

Avoid kickback on table saws.

The MJ SPLITTER Steel Pro easily installs on your table saw’s zero clearance insert, replacing the riving knife. It keeps your workpiece tight to the fence to prevent burning, and keep the kerf from pinching the blade, virtually eliminating kickback.

Henry Wang, Microjig Founder

The initial concept for MJ SPLITTERS was born from our best resource - customer feedback! Shortly after the release of the GRR-RIPPER, early adopters suggested a splitter system that would provide the same functionality as their splitter/blade guard, but would allow the GRR-RIPPER to pass over it. The people spoke, and we listened! MJ SPLITTERs are now the world’s #1 aftermarket splitter system.

MJ SPLITTER SteelPro 1/8" Full Kerf System

Steel core for ultimate stability and strength.

  • Package includes (4) SPLITTERS, a drill guide, and a 3/16” drill bit.
  • Designed for full kerf saw blades
  • SPLITTERS are reversible for offsets of 0.000”, 0.003”, 0.006”, and 0.009”
  • Kerf range:  0.118” - 0.145".
    Instructions for Phenolic Throat Plates
  • For 90 degree thru-cuts only.

Better protection, better cuts.

MJ SPLITTER SteelPro 1/8" Full Kerf System

The included precision drill guide aligns your drill with the dead center of your kerf by registering off of the kerf itself.

SPLITTERS are used in tandem to fill entire kerf.

The included Kerf Keepers are used when cutting hardwoods with potentially dangerous internal stress. If the stock closes around the Kerf Keepers, they automatically eject and remain within the kerf, preventing the stock from pinching on the blade.

MJ SPLITTER SteelPro 1/8" Full Kerf System

To account for runout, the package includes 4 SPLITTERS and 4 Kerf Keepers with built-in offsets from the center of the kerf.  Each side has an offset in increments of .003” to ensure a perfect fit.

Router Tables

The Grr-ripper provides incredible command over your workpiece on the router table. Whether you’re using the fence or freehand routing, its powerful grip controls stock and protects your hands from dangerous spinning bits.

MJ SPLITTER SteelPro 1/8" Full Kerf System

Table Saws

The Grr-ripper was built for the table saw. It acts as a moving blade guard, shielding your hands from the saw blade through the entire cut. Right out of the box, the Grr-ripper can cut stock down to ¼” x ¼”. Because it provides three directions of control, your cuts will be cleaner and more precise.

Jointers

The Grr-ripper’s proprietary Green Grr-rip material provides all the traction you need to properly flatten stock on the jointer. Because of its powerful grip, you can feed material over the cutter head without having to apply too much downward pressure.  The Grr-ripper makes proper face-jointing technique easy and safe.

Band Saws

The Grr-ripper's legs and main body maintain a constant 90-degree angle. It can be used on its side, which is ideal for resawing on band saws. The Grr-ripper glides along the table top and applies even pressure against the fence with your hands clear of the blade. Even pressure means less blade drift, resulting in smoother cuts.

Got questions?

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

Yes, please download and read the instructions.

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 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.

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.

How much space behind the blade do I need?

It all started in a garage workshop...

Henry was working on an intricate project and was challenged with cutting thin strips on a table saw. His frustration with traditional methods sparked one of the most innovative woodworking tools to come out in decades.

After countless hours and prototypes, the Grr-ripper was born. Henry has continued to innovate, and Microjig now offers multiple unique product lines all over the world.
