Thanks Guys for the tips, I'll look into the insert cutter. The mill isn't new ,but might as well be. My son is a mechanical engineer who designs and builds the machines that make the parts, He got the mill from work, they never used it for milling , only laser indicating. I has DRO, power feeds and yes it does have power down feed. I may be posting a lot as I have so much to learn and so little time! Thanks so much for the help- DRpatron (AKA: John)
