What are these tapered end mills used for · By the way I do have a bunch of tapered end mills bought when the local GE die shop auctioned off They are used for making dies with specific draft angles on the walls I tried to use one for reaming a tapered hole once and it made a mess leaving chatter marks in the hole All of my tapered end mills are marked with the side angle in degrees Larry Last edited by L Vanice 06 11 2019 at
