5Capacity is everything!
By Don Dequasie
This is my hammer drill and I can easily reccomend it. It is perfectly capable within it's capacity. Another reviewer said the drill was unable to drill a 7/8 inch hole. The biggest bit one could expect to use with any drill in this class is 3/4 inch max. And that in the low speed (only 3/8 inch in high speed). The dissatisfied reviewer may not have known what he was doing. My outfit was doing a big remodel last year, adding on to a house. The existing threshold was poured crete and had to go. My boss told one of the guys to drill a bunch of one inch holes along the doorway so as to be able to smash the crete away. The worker didn't know any better either and went at it with a yellow hammer drill (similar in size to this one) in high speed with a one inch percussion bit. The drill died in about 20 minutes. So the boss went out and bought the same-sized Bosch HD and it died that day too. Now he has a Makita but not the knowledge of capacity. They don't listen to me - I just work there. In closing, I love the RED tools, have a bunch of them, and they are always (except for miter saws and impact drivers - then Makitas are the standard by which all others are judged) the first I look at.

5Great drill for a great price
By P. Altenburg
I read a lot of reviews, and spoke with some contractors I know, and they all had problems with hammer drills of other colors. Milwaukee always got good to great ratings. I own one other Milwaukee, and it is a great tool too, so I thought this a good choice. I was not disappointed. This drill is powerful, light weight, and with a new set of bits, made holes in concrete, ceramic tile, and wood with ease, largest was 1/2". In wood with a 1" self-feeding auger bit it was unstoppable. I am only a weekend warrior, so I am sure this tool will outlast me.

5Excellent product!
By Paul C. Valcarce
First of all, it's very unlike me to take the time to go back and write a review for any product. However, I am beyond pleased with the purchase or my Milwaukee 5378-21 7.5 Amp 1/2-Inch Hammer Drill. I'm a professional architect and weekend carpentry warrior and based my opinion on such use.Recently the drill performed flawlessly during a deck construction project with ample power to drive through 6x8 beams with ease. Drill provides plenty of drive and torque for any wood application!The hammer feature is a little loud but that's what ear protection's for. This little baby is a work horse - absolutely no complaints. I love it and I'm sure I'll have it for years to come.
