When I started turning 30 yrs ago at work , we still used high carbon steel.High speed steel came along and changed everything for the good. I used aluminum oxide wheels with good success.Nothing like a tool right after sharpening With the new steels available, I thought I might take the jump. My question to those in the know is can I use my alum-oxide wheel to sharpen them or do I need a CBN wheel to get the most out of these tools .
