I always grind a small flat on round shank carbide mills used for roughing (don't want to take them out of balance for high speed) - A buddy showed me that he would grind it at a little back angle like a ball lock punch to keep it from pulling out at the same time. I've taken some obscene cuts with them in hard, nasty material and never had one pull out, break yes, pull no...
"You are technically correct. The best kind of correct"I mean regular non-weldon flat cutters, in a Weldon flat solid holder, smooth cutter shank- to set screw,
And yeah there are a ton of fucked holders around the shop. I have only worked here for a few months. And when you see the "Top" guy doing this, it makes me question the company. You should see how he builds through spindle coolant tools.....non sealed holders, if coolant comes through the hole at all he says that's " through spindle"
I've seen more than one Bridgeport with a ramped slot in the table.Or a mill table, I saw it happen to a guy who I was working next to, some years ago.
