NOTE: FIRST choice starting speeds are in bold type. As the average chip thickness increases, the speed should be decreased. *Material groups P, M, K, and H show recommended starting speeds for dry machining. For wet machining, reduce speed by 20%. *Material groups N and S show recommended starting speeds for wet machining. Not recommended for dry machining.
