Customers are mixed about the grip of the drill. Some mention that the hand grip comes in handy so that the handle doesn't snap their wrist, and the front handle allows them to give good support.

"...Drill got a little warm towards the end but no overheating issues...." Read more

Works well, until it doesn’t. Died a premature death.
Died a premature death after an easy unstressful short life. Bought it 6 months ago and used it to install 6 inch LED recessed lights. Cut 54 holes with it before it suddenly stop working. As you can see, I was even using a dust shroud with it. I take care of my tools, including this one. Still looks new but doesn’t work at all. Still under warranty, but a pain in the butt to have repaired and be without a drill in the meantime.

I drilled 20 holes into stucco and solid concrete block, 2-inches deep, with a 7/16 inch drill bit for a hurricane panel. Each took about 30 to 45 seconds. Easy with this drill. It's got all of the features that you might need, including a metal motor housing, an adjustable second handle, 2 speeds (each variable), a hammer on/off setting and a depth rod. The grips are perfect. The drill is heavy and well built. The case is sturdy and well-designed. Remember to wear a mask to protect against concrete dust and eye protection just in case something goes flying.

I recently cut down a couple of holly and apple trees and needed a powerful drill to poke 1" holes in the stumps so that I could pour in dissolver fluid. My cordless drills proved useless so I went to a local hardware store and bought an inexpensive model only to have it lock up and catch fire. Not a good experience. Soooo, even though I didn't have many other use cases in mind I purchased this DeWalt... and I'm very glad I did. It did get a bit warm, but punched dozens of holes in green hardwood with no problems. It's powerful but relatively lightweight and easy to control. I especially like that it's variable speed and reversible, takes 1/2 inch shaft bits, and holds up to a lot of abuse. I'm sure I'll find further uses for it in the future.

5.0 out of 5 stars It's a beast!
Reviewed in the United States on February 12, 2011
Style: Hammer Drill KitVerified Purchase
For years I done thing the hard way. A standard power drill and a masonry bit. Only drillig into concrete or bloock on occasion I didn't feel the need to buy a specialized tool just for that. I wish I had... The project I needed to tackle involved quite a bit of drilling into block. And this 10 amp monster ate right thru it! What used to take minutes (lots of minutes) took mere seconds. I was able to drill and mount using tapcons the entirety of all of my gang boxes and ledger boards on my garage revamp in just a couple of hours. And that included a lot of breaks :) I'm extatic with my purchase!!!

This drill features a keyed 1/2" chuck. A 360-degree mountable and removeable front pistol grip. Two drilling speed ranges plus the obvious hammer mode. It's a no nonsense tool that for it's size and weight is extremely well built and powerful. The guide is a terrific accessory that gives you precise deapth control. It also includes an extra large chuck key to save your fingers if changing out bits. Personally I think a second drill works better though. All in all, if you have a job that invovles putting holes in concrete, then you need to buy yourself one of these. Hands down then best drill I've ever used!

Reviewed in the United States on November 24, 2011

Great drill - 1200 watts thats power to spare and results in effortless drilling.

Variable speed, 2 gears, Hammer Drill function.

I did read somewhere that some people had problems with the drill bit slipping because the chuck becomes loose when using the hammer drill function.
My response to that is to tighten the chuck with chuck key in each of the 3 holes. I drilled 3 seperate holes each 20mm hole through approx 7 inches of granite using the hammer drill and an irwin joran drill bit, no problems not once did it loosen up.

I bought it for use in Australia so being that it's a 110v drill I hooked it up to my 2000w 240V > 110v step down transformer. Australia runs at 50 cycles while the US runs at 60 cycles doing the math I dropped about 60w of power not much of a price to pay with that much raw grunt.

Some may find it a bit on the weighty side, but I don't think it is.

It's a quality bit of kit, and I'm already looking at a DeWalt cordless for those lighter jobs when I need a cordless screwdriver.

Great purchase at half the price I pay in Aus for the same item.

4.0 out of 5 stars Lots of 10 amp power and reliability
Reviewed in the United States on December 18, 2012
Style: Hammer Drill KitVerified Purchase
I have been using the dewalt dwd210g, for a month now, and I love it because of the impressive 980 W power at 5.1 lbs, and its rather remarkable stamina and reliability. I decided to try the 520 because the guts are the same, the motor, speed, heat/overload protection are the same as its sister model 210.

The 210 is the same as the 520, with these changes:

(1) hammer drill
(2) two speeds (400-1200, and 800-3200 rpm)
(3) 1 lb heavier
(4) 1.7" longer.
(5) carrying case included.

The 520 shares the same flaw as the 210, that it does NOT do low speed rpm. (400 rpm minimum). Not good for steel. unless you pulse it. Thats why I took off a star. but hey, 10 amps of hammerdrill in a 6 lb package, thats not bad.

This is comes with standard adjustable drill chuck and NOT an SDS (spline bit) hammer drill. Any adjustable chuck will tend to loosen on continuous hammering, unless you tighten it correctly. The 520 comes with an oversized t-handle chuck key. Make sure you tighten all three chuck key slots and that should hold any bit in place, including round shanks.

5.0 out of 5 stars Great tool for home improvement!
Reviewed in the United States on May 18, 2014

I bought this hammerdrill after indecision between renting a rotary hammerdrill, buying a rotary hammerdrill, or just buying a regular hammerdrill. I am refinishing my basement and needed to drill 3/8" holes into the concrete in order to anchor my treated 2x4's for the wall framing to attach to. As I did not have a regular power drill, I was hesitant to buy a rotary hammerdrill as they all have SDS and therefore would require special bits. I'd rather have a hammerdrill with a standard chuck that I could also use as a normal drill for anything else. At the cost of only a little over $100, I decided it would be worth trying this out rather than renting a rotary hammerdrill for a few days. I was shocked by the performance. This thing drilled through the 2x4's and the concrete with no issues. It took less than 10 seconds per hole to drill 2" deep holes (3/8" Bosch masonry bit). I drilled about 100 holes and it only had trouble in 1 or 2 holes when it hit a rock in the concrete, but it eventually broke through it. Since then I've used it for drilling through lumber as well...feels like butter!
