- carbide on a 10 inch atlas, am I wasting inserts
Buy a few, not a shop pack. And don't hang them out an inch and a half. I still use them. Gus is still mad. Equilibrium.
- insert geometry, I bought three and they all look the same
Three CCMT inserts, three little codes, all described as general purpose. One cuts mild fine on the Atlas. One rubs. One chips. The catalog…
- import 6 inch chuck, runout, am I the problem

Shorter stickout, lighter pass, insert survived two gears. Finish is duller than I wanted. I'm keeping the carbide for the cleanup and I'll…
- carbide on a 10 inch atlas, am I wasting inserts
About 400 rpm because I got scared. Depth was probably too much, I was trying to get under the weld blobs in one pass. Stickout is maybe an…
- carbide on a 10 inch atlas, am I wasting inserts
10 inch Atlas, the lighter one, not a Clausing. I've been running CCMT inserts because I don't enjoy grinding and my HSS looks like a butte…
