Rated 5 out of 5 by from Quality A lovely example of precision and practical engineering. I have just completed my first job with this drill/screwdriver which was to re-fix a blind on a replacement window in my daughter’s room.

Rated 5 out of 5 by from Feels like a powerful and capable machine. Fed up of buying run of the mill DIY battery powered hand drills so I decided to splash out on this unit. Delivery as usual was excellent and next day. To date I have used the drill for a small number of holes in concrete block walls, the hammer action is very good, better than other drills I have bought, the electric brake is new to me and very quick. The chuck tightening system is also good, the ratchet action is much better than the usual "tighten by holding the chuck whilst the drill runs method". The unit is not heavy but feels robust and very responsive, normal screwing into wood and wall plugs is solid, I'm hoping the steel gears are an improvement over the usual nylon gears on other DIY type units. After some internet research I'm hoping this entry professional level Bosch drill offers what it promises...so far I'm very pleased with my choice, only time will tell.

Rated 5 out of 5 by from Just the Job! Had this a week or so after my old Erbauer gave up the ghost after nearly 10 years! I was going to replace with another Erbauer but this was on offer and came with 3 batteries, plus it has a hammer option which my old one didn’t. So far I’m really impressed and it’s worked perfectly for each of its “Combi” functions. I would definitely recommend it.
