I owned the V28 drill prior to this one and I must say the M18 has it beat hands down! I use uni-bits or step bits often and this drill chews through metal like no other drill I have owned.
This is an excellent product that displays a great amount of toque to get the job done.
First, I'll state that the drill itself, along with the M18 batteries, are great. If it wasn't for Milwaukee's poor service, this would be a 5 star rating.
While Milwaukee's V18 3.0 Lith Ion battery is GREAT and works with all the 18 v NiCad tools we all have, theses XC and compact 18v lith ion batteries ONLY FIT NEWER TOOLS
I own a sewer and water excavating company...so we have a lot of experience with corded/cordless tools of many brands. Hilti, Bosch, Dewalt, Makita. After owning several Milwaukee drills including the previous V18 hammerdrill, 14.4v drill, and M12 compact driver this drill takes it all.
