Annoying thin walled parts from 1/4 Sch. 80 stainless pipe, the drilling is awful due to the low material removal, it rips the edges right off of the drills at 60 FPM with HSS drills.
Turning, threading and parting is done at 250 FPM with carbide tooling, this could be done at much higher speeds.
Using an 8" 3 jaw chuck turns the coolant to mist at 2500 Rpm's which is a mess, a collet chuck does not cause this problem but for 200 parts it is not likely worth the time.
