Fantastic Drill
Got this with the matching fuel impact. I wanted a powerful drill in a smaller package, and Milwaukee’s m12 line fit the bill. It was a replacement for my old m12 brushed drill that i had lost (very sad day but then i got this. Insane amount of power for how small it is, very ergonomic and excellent build quality. Chuck feels solid and spins straight and true. I hope I never lose this thing.

Describe Yourself:
M12 gen 2 fuel hammer drill
My Milwaukee m12 gen 2 fuel hammer drill sucks. The chuck is hands down by far the worse. The wobble is so bad and it only like 2 months old. I have never seen a chuck this bad and it is suppose to be a premium tool. To drill precise hole I have to use my dewalt full size hammer drill. This is the reason I bought it, so I don't have to use my dewalt beast for small holes. It just sucks in have this m12 and it's a terrible tool.

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.
