MJ SPLITTER 1/8" Full Kerf
THE #1 AFTERMARKET SPLITTER

Avoid kickback on table saws.

The MJ SPLITTER 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.

How it works.

The best splitters you'll ever use.

MJ SPLITTER 1/8" Full Kerf

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

To account for runout, the package includes 2 SPLITTERS with built-in offsets from the center of the kerf.  Each side has an offset in increments of .003” to ensure a perfect fit.

The specially formulated plastic provides just the right balance of flexibility to prevent binding, and rigidity to prevent kickback.

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 3 directions of control, your cuts will be cleaner and more precise.

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.

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 bandsaws. 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.

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?

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.
