Great With One Suggestion For Improvement
The screwdriver is great. I love it. One improvement would be if the bit started rotating at a slower speed. Either variable speed, or start slow and ramp up to speed. Even at slow speed, 200 rpm, when you press the forward/reverse switch the bid starts turning so quickly that it tends to jump out of the screw slot. Both in forward and reverse. This is especially true on screw slots that are even a little damaged due to previous use. When working in a tight spot, hanging on by your fingernails, it can be hard to press the screwdriver bit onto the screw hard enough to stay engaged until the screw starts driving.

Milwaukee cordless 4v screwdriver
This is similar to one I had ten years ago. However this is much more expensive. The battery life is ok, could be longer since it is LIO and not nicd. Simple to use variable torque is nice but wasted on a unit this small.

More is not always better
It`s a good tool. The "BUT" is it`s larger and somewhat clumsy compared to the original. The charger feels flimsy and at times takes a little finesse before it accepts the battery. Still it is handier and easier to carry than the pistol shaped drivers.

Looking for one of these for years!
Very fine portable screwdriver, nut driver and drill. Had a marginal one, years ago, which died. This one will last and last. Thank You, Milwaukee! Bought one for my brother-in-law.

Great for what it is.
Ahh, good ole Milwaukee power tools. I got this little beauty as a companion to their M12 Fuel Impact Driver. I use this for very sensitive applications like electronic work, and the Impact for everything else.

When I first took it out of its box, I was surprised with how small it was. The ergonomics are pretty good for it just being basically a 10 inch long shaft. The rubber on the tool feels good on the hands. The transition from it's "Straight" grip to it's "Pistol" grip feels very smooth and feels like it wont go from one to the next on accident while working.

The Battery light indicator is a definite plus to the tool as well. I also really dig the forward clutch, as when it's activated the tool just stops instead of making that annoying clicking noise that most clutch systems do.

This tool has around 40 pounds of torque and 21 clutch setting with about 2 pounds at it's first.

Suffice it to say this thing wont be driving deck screws any time soon. This particular tool was designed with electricians, Computer Tech's, and just regular home owners in mind. I personally find this tool very useful for building computers in my shop.

Overall, I would highly recommend this tool for anybody who wants a good, lightweight, low torque, and very precision oriented tool to preform lightweight and sensitive tasks in their shop.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
