It was a fight with chatter on a 1 dia. by 2 deep bore with my Criterion DBL-202 head. Slowing down the RPM helped but I still had chatter no matter what speed or feed.
I know what the problem is: the brazed carbide boring bar was too thin for that depth.
Not interested in any more boring bars that I have to resharpen. I want to replace an insert and move on.
Im considering an indexible boring bar ( a quality USA made product) and have these questions:
Lets assume that 90+% of the boring is in aluminum or brass.
1. Boring bar material. HSS or Carbide?
2. Inserts. HSS or carbide?
If steel or cast iron is also a possibility, does that change the answers to questions 1 & 2?
Ive looked at the Criterion bars and the A.W. Warner bars and HSS inserts. Any preference or is there a better choice than either.
