I know what its like to wrestle a good quality 1/2" drill motor, and don't really want to experience this 3/4" one. One of my employees was using a 1/2" up on a machine table, it hung when he wasn't balanced and he was then flung off the table and onto the floor. Only his ego was injured.
Spro mentioned the trigger, I had a small drill hang and when it twisted it wedged my finger onto the trigger. Ouch#! That only happened once as from that point on I checked to see where things would end up if the drill motor twisted around.

grind a very slight flat part way on the drill shank. It WILL hold but u may find yourself breaking drills because of no slip. If u leave half the shank untouched, the drill will still run true when put all the way in a press or mill.

I have a non-variable speed, 1/2" Montgomery Wards drill from around 1961. If that suckered ever jams, you're likely to break an arm!

Sure they have serious torque. Breaking an arm is a stretch unless twisted off a ladder, railing etc. Let's say the drill grabbed and twisted you off the ladder on a gangway. We fall and within seconds, find we are still unbroken. Two seconds later the drill motor plummets to where your head was.
