Hello,

I am making a groove that is close to an inch deep on a side in 304 SS material and I am using a groover that is 1.25 long. I am using a feed of .002 with a SF/M of 200 which usually works good for most grooves.

With this extra long tool though I get dimples on the sides and sometimes chatter in the bottom. Is there anyway to get a nicer finish or is this just the nature of such a deep groove?

The toolmaker is Seco and these are the suggested feeds and speeds.
