A true solid carbide e/mill/slot drill is expensive but a truely fantastic tool,the price is a give away if they are cheap it will certainly not be the real thing

I've dealt with that seller (Kevin) for some years and he's an ok bloke. Had loads of CAT40 tooling from him, and once met him when I bought a large tooling cabinet.

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?

Your assumption is correct.
Honour your mentors, and pay it forward.
