Brazing carbide to a lathe bit

[stuckmotor]

I've been watching various people braze carbide to the end of a piece of steel to make a lathe bit and never see them reharden or temper the carbide. Does carbide not lose it's hardness at brazing temperature?

Nope. Carbide isn't heat treated for toughness. It is what it is.

No, it doesn't need anything after brazing. However, I stopped needing to braze my own carbide years ago. Pre made lathe cutters are available very cheap that can be ground into the shape you need.

Thanks guys. That's what I needed to know.
