Silicon Carbide Discs

These are a handy tool you can easily make. You need a small screw in mandrel and a SC stick or plate. Cut out the circle with the core drill in a drill press. Drill the 1 ish mm hole so it fits your mandrel.

The mandrel, SC stick, drill bits and core drill can be brought from Richon Tools.

You need to keep them true as they may wear unevenly making them chatter.

I’m not responsible for anything that happens to you if you make these. Wear appropriate protection.
