A big step up from the previous model, slightly shorter, a little lighter, but obviously more powerful. This Bosch is as good as any other major name at this price point. And it's got the metal chuck that was only on the dear, full pro drills.

Direct replacement for old model which had just worn out through use Smaller, lighter and better chuck. Very happy.

Well made product solid good torque for general use Robust gearbox and a chuck that will not get damaged like a plastic one when catching materials if it catches on close work piece
Everything is good, I recommend
Excellent product
Compact and well constructed
This is not the very latest model, but is perfectly serviceable. I already had an old Bosch combo drill, with a couple of batteries, so it made great sense to purchase a new, body-only model. The old one was failing in the chuck/clutch department and I'm pleased to see that this seems more robust and positive on the new drill. I've used it a few times already and it seems very much up to the job, adequately powerful and good value for money.
A good lightweight drill with plenty of power. Benefits from having a metal chuck.
Excellent...works and powerful
