Hammer Drill Reviews
Our Top Pick is the Dewalt DW511
Drills are a staple in any workshop and are considered essential. The hammer drill has the convenience and power of a standard drill but contains the ability to bore larger holes into either wood or harder surfaces like brick or concrete. Hammer drills are not an expensive addition to your tool collection but can add a very convenient feature that few tools are able to perform.
Hammer drills were first designed to drill rock for excavating purposes in the mining industry. Today they are used by carpenters, masons and homeowners who like to work on DIY projects. With low price of hammer drills, they are not an expensive piece of equipment and even occasional use will warrant a review. Our research and testing showed that lower end models did not have the power more expensive models offer and require more time and more downforce to get the job done. Lower priced hammer drills are also limited in the size of hole they are able to produce.
After reviews and testing the top models the Dewalt DW511 stood out from the crowd with its power, design and ability to bore holes in the toughest material. With 7.8 amps of power and a variable speed motor you will have the amperage required to complete any home project.
Who Should Buy This
Hammer drills are built to create larger than normal holes in either wood, concrete or other difficult material. They have the power to drill through rock and the hammer action gives it more power when it comes to rock and concrete materials. If you ever need to drill a hole or shallow indention in lumber, stone or concrete, then a hammer drill is built to get the job done. They are widely used on construction sites and for homeowner renovations. They can also be very useful when building furniture or other projects that might call for a hole to be drilled that is larger than a few centimeters. The ability to hang a swing, place pot holders on a brick wall or add a railing to concrete stairs will all require the use of a hammer drill.
What Makes a Good Hammer Drill?
This large drill offers a hammer action when drilling into masonry or other rough surfaces like rock or stone. A switch or lever will typically engage the hammer action when it is needed. Most offer the versatility of giving you the applications of a traditional drill along with the hammer action feature.
A basic hammer drill consists of 2 cam plates that pulses the check forward and backward as the drill spins. This pulsing action is referred to as hammering. Because of the high speeds on the drill vibration and the amount of hand force required to drill an item are key concerns when considering a hammer drill. Rotary style hammers have less vibration because they have a piston design as opposed to the cam style drills.
When buying a hammer drill it is essential to look at how the tool will be used. The maximum size bit the drill will take will impact the price. The larger the maximum bit size the more expensive the drill. It is best to buy a drill with a higher maximum bit size than you will use frequently. This prevents the drill from being used at maximum capacity on a regular basis, which will wear the motor out faster.
Other accessories might include a chisel bit or a mini jack hammerthat will increase the tools versatility. When dealing with hard surfaces like masonry and concrete, the drilling process can be very hard on a weaker motor, even if you don’t use the drill very often, impacting the life of the drill.
Power is measured by both amperage and blows or beats per minute (BPM). Other things to look for are easy bit changes or keyless bit changes and all metal parts. Checks with plastic parts will not last as long as metal ones. The chuck size for the drill will determine the maximum size hole you are able to drill.
Hammer drills come in both corded and cordless models. Cordless drills offer the convenience of not needing to be connected to electricity, increasing the portability. However the sacrifice is in weight and power. The battery makes the unit heavier and the unit will generally not have as much power as a coded option at the same price point. This can impact your budget if you want the cordless option and the power you could end up paying a lot more for that convenience. If you plan to use the drill on a daily basis, it certainly might be worth the investment.

The bit you choose should be specifically designed for the material you are drilling.
The lightweight design is only 4.3 pounds giving you hours or work ability without your arms getting tired. The powerful motor also reduces the downforce required to get through tough materials, enabling you to work longer and faster.
The drill comes with a side handle that allows you to balance the weight during the drill giving you more accuracy in the desired depth and greater control over the action. The side handle can rotate up to 360 degrees allowing you to position it where it is most beneficial for the angle you are working. There is an integrated depth rod which gives you precision depth measurements into the surface area.
The maximum power output is 650 watts of power giving you the power of more expensive models at a very affordable price. The maximum drill capacity is ½ inch which provides the most common size holes that need to be drilled in steel. Wood has a maximum capacity of 1 ¼ inches and 5/32 to 3/8 maximum capacity for concrete work.
Who Else Likes It
The pros at Popular Mechanics said this about the Dewalt DW511, “Guts. This toll has got’em. It’s not a matter of speed – it’s what you get when you combine motor torque with a solid drivetrain…The Dewalt powers through with minimal kickback while requiring little downforce from the user.”
Amazon reviewers gave it a 4.5 out of 5 stars with 164 reviews. One 5 star reviewer wrote: “I had previously tried to mount railing and accessories around concrete steps and our pool, using a rotary drill with masonry bits (unsatisfactory)…nails didn’t penetrate and it really chipped out the hole areas that then required patching…I was so pleased to be able to drill quarter inch holes about 2 inches into the concrete, each in about 30 seconds…You won’t go wrong with this drill, and it has a rotary setting too for conventional drilling jobs.”
The Step Up
The Milwaukee 5380-21 is a ½ inch hammer drill with 9 amps of power for more heavy duty drilling.

Care Use and Maintenance
The drill bits have flutes that are designed to capture the sawdust, rock or metal that remains after the hole is drilled. Bring the bit up frequently to clear the flutes and the debris that is created from the hole. This will allow the drill to be more efficient.
Do not force the drill. Let it do its job. Hard surfaces like masonry and concrete take special bits but also take longer to drill than sifter lumber. Too much down force can overwork the motor or break the bits.
Select your drill bit based on the material you are drilling.
Use the side handle and the depth stop to prevent from over drilling. That will result in burning through bits much faster. Often with concrete or masonry drilling the object is not to drill all the way through the surface but to create anchors and a hollow core for support or leverage.
It is good practice to start by drilling a smaller hole and then working up to the final size you want. This practice reduces the load on the drill and provides greater precision with the finished product.
To keep the drill lasting longer make sure the end of the drill bit that goes into the drill is clean. Debris on the end can create jamming and wear on the motor.
Generously lubricate the shank of the drill with each bit change. This will make the bit holder last longer.
As always follow the manufactures recommendations with regard to care and servicing.
Wrapping It Up
Hammer drills can be a great tool to have if you have the need to do any drilling with brick or concrete or have the need to drill larger holes. They are built for tougher conditions and are widely used by homeowners. The cost is very reasonable making this a tool that once you get you will wonder how you ever lived without it.
