This is one of those "when you can't make it with an electric driver and you need a speedy go-to screwdriver" screwdriver. The bit holder doesn't stay on the shaft as it is supposed to do. Other than that it is a welcome addition to my tool box.
Thought this would be a one up from my trusty Klein Rapi-drives. The T-handle would be great for more torque. First time I used the Mach Driver , I about broke a knuckle. The handle unlocks and flips sideways letting your hand contact the work surface . Not safe around electricity and downright painful otherwise. You cannot put any pressure on a screw to tighten or remove unless you flip the handle to t- mode. Sorry Craftsman....back to the Klein Rapi-Drives until you put a safety lock on the handle or perhaps change the shaft angle to keep the handle from disengaging. Looked nice....but....no cigar!! Back it goes...........
works ok, but I think I can still spin a screw driver faster than using this thing. And it squeak, if I have to use it in a room with people it will be way to noisy. Not the quality I expected from Craftsman.
Makes taking screws in and out very quick. Used this to replace about 15 outlets in my house and used it to take about 30 screws out of a project and back in later. So far so good and cut a lot of time.
Well worth the price.
When I first received new Mach 11.. I was do doubt Courious. I must say once again..way to go craftsman tools.??
