So... There is no way to turn carbide ? I have turned the shanks of many drills that I thought
was hard but this bit I needed to sharpen my cermets about 20 times to get this one job done.
It would only take a very small curl off no matter how hard I would push the cutter. I was using
a diamond stone to sharpen my cermets . A few time I could not get it to cut at all. I would resharpen
over and over until it would cut again. I tried different angles, speeds and feeds. Nothing seemed
to help. My carbide cutters would not touch it. If not carbide what might it be?
