Matrix Precision Replacement Carbide Cutters

Set of two cutters.

We have three thicknesses. Use .117 for a tight slide fit on a 1911 or 2011, if desired. For slides from, the .118 seems to work well.

The .121 thickness is specifically for cutting Sig rails. The cutters can be changed out on our Matrix Precision Rail Cutter.

Carbide Cutter Installation Instructions

The set screw that holds each carbide cutter was adjusted before shipping, and should not normally need adjustment. If there is any up and down movement, or if you are installing new cutters, carefully adjust the set screws located in the center of each cutter housing to keep the cutters pressed down onto the fixture to get an accurate cut. Cutters should not have any vertical play, but should still move back into housings when pushed in by hand (though with some effort) when the adjustment knobs are retracted. VERY IMPORTANT: If the set screws are too tight you will chip your carbide cutters on the retract stroke of the car. They cutters must be loose enough that you can push them with your fingers. Also, never reverse the screw when in the middle of a cut. That will also chip the cutters.

See video for a good illustration of cutter adjustment about 15 minutes in.

Just received the 2 frames this afternoon. They are fantastic, as usual. You have certainly converted me to become a builder rather than a buyer.

Your rail cutter is amazing like I knew it would be. I think with your tooling almost anybody can perform an above standard job.
