Looking for a better indexable drill than what we currently are using (Allied/AMEC T/A Style). We don't have any thru coolant machines. We have been using this same style since the 90's. We have good success with them in the mills but it seems like we are destroying inserts & holders whenever we drill in the lathes. Most common is the insert grabbing and then twisting the holder shank. I am sure its 95% operator error with the speeds & feeds, likely driving it to hard but just looking to see what everyone else is having success with. We mostly drill Carbon Steel, 4140HT, 410HT & Inconels. Machines are all Haas & SMEC.
