Milwaukee Sharp-Fire driver?

[Jason280]

I picked up a Milwaukee Sharp-Fire driver yesterday, type that uses screws on speed strips for drywall and subfloors. Right now it has a standard #2 phillips bit, but it doesn't rotate when the drill trigger is depressed. The drill turns, so I assume its simply come out of the internal bit holder.

Anyone familiar with this system? How do you like it? I'd like to order a few thousand 1 5/8" screws, but need to figure out how to operate it first. I've been able to find a manual for the power unit, but nothing on the sharp-fire system itself.

Any suggestions?

I think the #2 engages when you apply pressure to it while driving the screw.

Have you tried it?

Yeah, I tried that...no luck.

Ok, think I figured it out...found some Hitachi branded screw strip that work with the system. Pulled the screw feed system off the power head, and found that the bit is not staying locked in the collar. I think the slide lock may be jammed up, so I'll have to troubleshoot it a bit more....

Finally figured it out. The Milwaukee power head doesn't use a typical slide collar to lock bits in place, it instead rotates around to release the detent. Maybe its supposed to slide, but I never could get it to work this way...but rotating it until the detent locked back in place solved my issue. Drove a few 1 5/8" screws with it, worked like a charm...of course, this is after I finished putting up 40+ sheets of OSB on the interior of my shop!

They're good for subfloors and some other stuff but I never liked them for hanging drywall. Just can't get into the corners good. But they are nice for laying down subflooring and depending on the length of it you don't have to bend over at all.
