  • Solid choice for everyday
This m12 impact has replaced my m18 impact in my tool bag. Got enough torque for many of my daily needs. Have not tried driving lags with it to see what it can do. Compact and light enough to carry all day. Battery life isn't an issue as I have plenty of m12 3.0 but you can see a drop off in rpm, torque and overall performance once the battery gets low ... show more

  • Milwaukee M12 Hammer Drill will buy this product again
Great quality, power, works very fast. My Son loves the way the drill hammer drives and easy to use and very light in weight. Great value for the money.

  • Great tool
Fantastic good power light and smaller than my bigger version of this tool. Easier to carry in my tool bag.

  • Plenty of torque and verve.
This 1/4” driver M12 compact is a nice size to have for interior speaker cabinet or furniture work. Plus, under sinks and floors. Has a nice bright led. Good trigger and easy to utilize forward/brake/reverse thumb push-button. Nice grip even wet. I had 2 of the M-12 batteries from my Milwaukee plumbing kit just itching to go to work. For a bare brand-new bate tool in a sack; I am quite pleased with the price/quality ratio. The small tool will torque (Tore Cue) a weak wrist so be careful. Brushless is best. Premium feel. Good cracker. ... show more

  • Great little 12v impact driver
I bought this as a secondary to my 12v fuel impact driver so I wasn’t always having to change bits. That being said, while this isn’t quite as capable as that little monster, this still has a place in my every day tool set. I work as a Millwright and having something super light and compact to sen fasteners home on lighter weight material or with shorter length fasteners is a huge benefit. These 12v tools really have retired my 18v and 20v sets for everything except the highest demand jobs that require a lot of current to keep the tool running. I will say that this doesn’t have the quick connect collet so you have to pull the cooler out to seat a bit. Not a big deal for me as mine lives the entire day with the same bit in it but if that’s a deal breaker for you, look for the 12v fuel. ... show more
