How to Grind Carbide Cutters

Adjust the tool rest mounted to the front of your grinding bench so the tool rest angles downward 15-degrees.

Turn on the grinding bench and wait for the grinding wheel to reach full speed.

Place the carbide tool blank flat on the tool rest. Angle the back end of the tool blank to your right approximately 15-degrees. Press the tool against the wheel. As you press, the bottom right edge of the tool will start to cut first. As the grinding wheel removes material, you will cut a 15-degree angle into the end of the carbide cutter vertically and laterally. This creates clearance on the front end of the tool.

Rotate the tool so you can grind the left side of the tool. When you look at the tool blank you can clearly see the carbide soldered to the top of the blank. One side of the carbide tool sticks out slightly over the edge. This is the side of the tool you need to grind.

Hold the tool straight against the grinding wheel and press the cutter into the wheel to remove material from the left side of the tool. Stop when you have a consistent radius cut into the side of the tool that goes from the bottom of the tool to the top of the carbide. The radius should run the fill length of the carbide insert.

Remove any burrs from the cut surfaces with a diamond encrusted file. Be careful not to remove any sharp edges. The sharper the tool the better it cuts.
