We have a bosch 5 amp 550 RPM 1/2" drill... the things is an absolute beast, and great german engineering failed when it came to the front handle design, it slips and spins, and the trigger lock is on the right side of the handle.. Being a lefty, that's where my palm is, as soon as you squeeze, you hit the trigger lock, if it binds, it's wrapping up the cord until it pulls itself unplugged... I've had to drill big holes in wood on top of a ladder... your butthole sure puckers up!
My 1/2" 8 amp Craftsman (Dewalt 505 is the rebranded newer version) is far faster but doesn't have the torque.... but it was designed far better, the trigger lock is on the front side of the handle and you have to pull it upward.. no accidental locks, and the front handle really locks hard so you can actually hold it
