Use a magnet?

Yes, the carbide should not stick to the magnet as hard as steel.

thanks, ill give it a go.

If you have anything to compare, the carbide will be quite a bit heavier than steel.

Personally, I'd hit the back of it to a grinding wheel, or chuck it up in a drill & hit it with a file. No affect -> carbide.
Or, get Chuck Norris to bite it,, measure the marks.

I think you will find that with a discriminating eye, the carbide's a bit darker gray, for lack of better terminology. The stainless ones are more "bright" if you will...

OK Ben. There are no Stainless cutting tools. The are tool steel. You are correct on the color though. How is Arizona this time of year?


Misread OP's post. Ground tool steel would be better than stainless for the pilot too though.

I believe the OP is talking pilots, not turning tools. Also heard it was 120+ in Phoenix yesterday. In my judgement it is steamy in AZ this time of year
