--- Quote from: Will_D on October 22, 2015, 02:40:47 PM ---With regards to the ARC Ripper end mills with the TiAlN coating specifically for 303/304 stainless I must say I am very impressed. On my SiegX2 the 14 mm (on 12mm shank) is a work horse.

However I naturally have a question which applies to other coated tooling like TiN drills and milling cutters:

What happens when you sharpen them?

I assume the coating is a micron or two thick and the resharpening will remove the coating so you are just back the basic HSS alloy?

Just bumping this as no replies to date!

What happens if you re-shrapen coated tooling?

Joules:
Your assumption is correct.
