Very good tool at a very decent price
This is a rugged small footprint fastener/screwdriver/drill.
It does lack some power when using with the drill torque setting, but I still was able to drill a 2" hole with a Hole Dozer bit in a did smell like it was heating and the battery drained but I still got it done.

When used to fasten bolts or screws, a single battery will last a very long time.
As a matter of fact, I rarely use my M18 Drill anymore because I have this one.

If you are looking for a simple drill for the house, you will get quite the bang for your bucks with this. Just keep in mind it is not as powerful as a bigger drill but still, you will get a very long way with this tool.

For professionals, it's heavier than other brands but the tool can take a beating.

Great tool, it's a screwdriver not a drill dummies
Great for small fasteners and hose clamps. Not a fan of the size of the chuck. I understand having a variety of tools but you're kind of overdoing it there Milwaukee. Makes it hard to know which model is best for my needs. Bought this two days ago and then look online to see a model that is not only better for my needs, but better overall in my opinion.

I would never buy this product again.
Have not found anything great about it except for the one hand insertion chuck. Tried drilling a hole in thick wall pipe and my life expectancy is not long enough to wait for it to penetrate.
The MAJOR problem with this thing is 500 RPMS! I bought it to be in between my Hitachi 12v hex impact tool (0-2500 rpms and 1100 inch pounds of torque beyond that as necessary) and my SKIL extra tool, a cordless 3.6v screwdriver.
Unfortunately, it is almost the same as my SKIL extra tool in feel and apparent power in drilling and VERY slow. though I know there must be more there somewhere but....... I end up drilling holes with my Hitachi which has gobs of power at only 12v.
And the speed to vary as necessary to a USABLE drilling speed whihc was a lot more than 500rpm.
At the very least it should have had a two speed switch, hi and low.
Well at least I got a great price and extra batteries plus a mini sawzall.

I love this, It's perfect when I'm doing PM's (HVAC Tech, it is small,light and has enough power to get the job done. I have a M18 impact and a Hammer-drill, if I need more power.

My first M12, I utilize my M18 tools all the time but wanted something a little smaller. I was definitely impressed with this. The first time I tried this out I brought along my M18 impact driver because I wasn't sure It would be able to get the job done. This thing did everything I asked of it.

My Go To Driver
You may forget how to use a regular screwdriver.
Great torque for screwing or drilling.
My only dig, the fwrd/rev button allows unintentional direction change if your not careful.

I want the exact drill as picture i have ordered 2 on internet and the are both the new style can you help me
Dan on Mar 16, 2016
BEST ANSWER: I have owned this drill about 6 years, I love it. The main reason is the
hex chuck, it will eject the bits. I bought the new one because I wanted
the same in case the old one "wore out" . The new one does not "eject" the
bits, the main feature for me, I install kitchen cabinets and it was very
easy to change bits one handed. Other than that it is a great driver, long
battery live, etc. Hope this helps
are there drill bits compatible with the 2401-10 cordless screwdriver?
joyce on Jan 21, 2013
BEST ANSWER: Any bit can be used with the screwdriver as long as the bit shank doesn't exceed a 1/4 of an inch.

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.
