Carbide or steel cuters?

[tenring]

I have a bunch of K&M neck turners. Some are carbide and others are steel. How can I tell which is which?

If they are individual solid bits same size the carbide is the heavier of the two.

Typically carbide is the darker gray of the two.

Carbide is not magnetic

Carbide is not magnetic

"In its raw form tungsten carbide is a powder. It's shaped in a mould and often cemented with a variety of different things which are magnetic."
