DEWALT DWD520 Vs. DWD520K VS. DW511 Hammer Drill


Hammer drills are highly specialized power tool that are engineered particularly for driving and drilling screws into bricks, concrete, and other masonry.

A hammer drill’s strength is in its pulsing hammer that essentially feels like something is smacking the rear of the tool with an actual hammer while drilling. That’s why, hammer drills can be quite difficult to operate, and normally comes with a physical handle in order to control it effectively.

Hammer drills are what you want if you’re planning to drill into concrete. However, you don’t want to use it for anything else that your wrists won’t be able to handle.

Amazon-ButtonWhat You Will Get With This Product?

First of all, this power tool from DEWALT is a corded hammer drill so you won’t get anxious about running out of charge in the midst of your task. DEWALT DWD520 comes with a 10 amp motor that delivers plenty of torque to drill up to 1-1/2 inch in wood, ½ inch in steel, ½ inch in concrete, and ¾ inch in masonry. Obviously, that’s for bit size and not the depth. In terms of maximum BPM or blows-per-minute in its hammer mode, it can deliver up to 56,000 BPM.

Furthermore, if you want to use drill only mode, you can easily turn off the hammer mode. It comes with two-speed transmission and comes with a variable speed trigger. These 2 speeds are 0 to 1,200 revolutions per minute, and a high gear of 0 to 3,500 revolutions per minute. The manufacturer advices when drilling to metal that users use low speed only and the drill must be lubricated a bit with oil before use. DEWALT also mentioned that this power tool is perfect for removing and driving TAPCON Tapper screw anchors in concrete.

Its soft rubber over-molded grip and two-finger trigger makes this tool comfortable to use. That’s advantageous since this hammer drill is not a lightweight tool. It only weighs 6 lbs. and comes with a pistol-grip format. Part of its nose’s weight comes from its protective metal housing which makes it resistant to sudden falls.

Also, the hammer drill in this kit has a 360-degree rotatable soft-grip side handle. This is a beneficial feature when users drill on extra tough materials or need a plenty of repetitive drilling. This DEWALT kid also comes with a steel depth rod.

If you have never used a depth rod before, you’d want to see it this way: loosen the bit and pull on the rod until the distance between the tip of the depth rod and the bit is how deep you want to drill. Then tighten the bit and drill into your work-piece until the tip touches it.

DEWALT DWD520 also has a chuck key. This chuck is ½ inch so it’s suitable with a vast range of bits. However, there have been some certain complaints from verified consumers’ reviews that the chuck doesn’t completely hold bits tightly enough. Now if you have never encountered how to deal with a keyed chuck before, you’d want to do this:

Manually open the chuck with your hands. Turn its collar until you can insert the shank of the bit. DEWALT suggests putting the shank for about ¾ inch inside the chuck. Then tighten the chuck again using your hands in a clockwise direction. After that, use the key and insert it into each of the 3 holes and tighten strongly. Now in order to remove the bit, just put the chuck key into any of the 3 holes and turn it in a counter-clockwise direction. When the chuck starts to open, turn it the rest of the direction by hand. If you don’t really like keyed chuck, any DEWALT service center can conveniently replace it for a keyless unit. But the thing is you might need to ready some extra cash for the service.

And lastly, you should remember that this unit comes as a bare tool only. Meaning, you won’t be getting any kit box or carrying case, or other accessories aside from the depth rod and auxiliary handle.
