Use it for general drill use. Has enough power to do the jobs needed. Battery life seems to be good. Replacement battery prices could be better, but will not likely have to get one for a while.

Great product
I’m a service technician for a Master Ingersoll Rand air compressor distributor and have always used IR cordless tools. I decided to purchase Milwaukee out of price and availability, as IR tools are overpriced, tend to not last very long under pressure, and have to be ordered online. We are all rough on tools and need reliability over everything else in my career field. This M12 brushless hammer drill has already withstood more than my 12V 1/4” hexbit IR driver could ever do, and the battery life is much longer in comparison. I will continue to purchase Milwaukee tools.

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.
