DEWALT Hammer Drill, 1/2-Inch, 10-Amp, Pistol Grip (DWD520)

great quality

Buena potencia, excelente tamaño, fácil de usar!Buen precio.

I bought this because I needed to drill 3/8" holes at least 2" deep in a 40 year old concrete floor, to place four anchors on the base of a floor drill press. When the slab was much newer I had drilled 1/4" holes with a non-hammer drill for a workbench, and it was very difficult. The first news is how much better the whole process works with a hammer drill, but I guess that comment is about the entire category of tool and not this particular one.That said, this particular drill looks quite well put together. It feels heavy and sturdy and the balance is good. Holding it comes naturally, and the speed control trigger feels perfectly sound. It has two drill modes plus one hammer drill mode. According to some online advice, I started my holes in drilling mode, which vibrates less and is easier to aim and center. As soon as I had a pocket deep enough to hold the drill bit on target, I switched to hammer mode. The hammering action is faster than I anticipated -- I was expecting to hear a woodpecker, but it sounded like an air impact wrench instead, quite a satisfying howl. I used it with a DeWalt concrete bit. I don't think any of the holes took more than a minute.I definitely recommend this. I also have a number of other DeWalt tools and have found them all good.I'm also asked to rate the Thickness, the Sheerness, and the Warmth of this product, but I'm not going to do that. I will say, though, that it warmed up a little bit, so if my hands were cold I might have enjoyed that, but it never felt hot.

C'était pour un cadeaux et l personne est très satisfaite. Fonctionne très bien.

While I am moving most of my home tools over to battery-powered, sometimes I need a drill motor with exceptional power, and this is it. So powerful, in fact, that it pays to use the second handle when really putting the workload on it or it will twist your wrist. Very good tool when needed.
