What is a Hammer Drill?
A hammer drill is an upgrade on the regular ole drill. What’s a drill you ask?
A drill is a tool equipped with either a cutting or driving attachment. They are used for boring holes in different materials or fastening them together with the aid of fasteners like screws, bolts, nuts etc. Now, let’s go on to the hammer drill.
A hammer drill is a rotary drill with a hammering action. This hammering action provides short and rapid impacts (measured in either blows-per-minute or impacts-per-minute). These short bursts of power allow the hammer drill break down hard material like concrete, wood etc. It also allows the hammer drill bore holes in various materials with little extra effort on the part of the operator.
How does a Hammer Drill work?
They say knowledge is power. That’s why you have to understand the basic principle of how a hammer drill works before you buy or even use one.
A hammer drill works just like your basic drill with just one major difference. You guessed it, it has a hammering action. The hammer drill has the following basic parts:
The Vibrating chuck
This is the part where you attach your drill bit. The chuck is also connected to the hammer mechanism. It moves back and forth when the hammer function is in use.
This is the power house of the entire hammer drill. The motor powers both the rotary and hammering action you notice when you use your drill. The motor can be either powered by electricity or batteries.
The Cooling fan
This is also an important feature in a hammer drill. Heat is known to wear out mechanical parts. A fan prevents that by keeping the motor cool while you drill.
The Hammer mechanism
This is what produces the short powerful thrusts that enable you drill into concrete, blocks, bricks, cement, wood etc. The hammering action is provided by two cam plates that make up the hammering mechanism. These cam plates make the chuck pulsate at high speed back and forth while the drill spins on its axis.
The Rotary switch
This selects the mode in which you hammer drill will run. Position right and counter clockwise is the drill only mode. The opposite direction selects the drill and hammer mode.
Why Buy a Hammer Drill?
Now that you know how a hammer drills work, why should you even consider buying or owning one? Here are a few reasons:
- 2-in-1 action: The hammer drill can work as both a regular drill and as a hammer drill. Its dual function means this tool will have many applications in your home. When you’re not using its hammer function, you can use the drill only function.
- Cost effective:Buying a hammer drill is cheaper than renting one anything you need to bore holes or even fasten things like shelves or cabinets to walls. Owning ones saves you on all that extra cost.
- Easy to use: The hammer drill is easy to use. Anyone who has read the user manual can operate this tool with ease.
- Better than a regular drill: The hammer drills bore holes in masonry and wood faster than regular drills. And best of all, you can switch off its hammer function and turn your hammer drill into a regular ole drill for non-masonry related activities like drilling holes into wood.
- The hammer drill is the best tool for you if you work around masonry like concrete, cement, bricks etc. If you require the right tool for masonry related tasks, the hammer drill is it.
Types of Hammer Drills
There are many types of hammer drills out there. But we’d be looking at the two major ones. These are:
Cordless or Battery Powered Hammer Drill
A cordless hammer drill is one that is powered by batteries. It does not have a power cord. The batteries are usually of Lithium Ion variety.
Cordless hammer drills are usually batteries rated at 18 volts or above. Nothing beats the mobility a cordless hammer drill brings. Because it is battery powered, you can use this type of hammer drill far away from a power source.
Owing to their batteries, they tend to be heavier than the electric hammer drills. Also, the operator is constrained by battery charge. If you’re battery is low, you’d either stop working so you can charge it or you have to buy extra batteries which is just extra expenses.
Electric Hammer Drill
The electric hammer drill comes with a power cord. It is powered by electricity. These hammer drills are very light and easy to hold for longer periods.
Electric hammer drills are rated between 600 to 1000 watts. They have a constant power source and hence, they tend to produce more torque than the cordless varieties. With an electric hammer drill, you can work for long periods without stopping. No battery to hinder your progress.
The only drawback to the electric hammer drill is the fact that you can’t use it too far away from a power source. Also, they are not very easy to manoeuvre in tight corners because of the cord.
Cordless vs. Corded Hammer Drills: Any Advantages
We bet it’s confusing to decide between the corded and cordless hammer drills. I’ve compared them according to some features listed below:
- Weight: When it comes to weight and compatibility, the corded hammer drills (or electric hammer drills) are generally much lighter than the cordless varieties.
- Mobility: The cordless hammer drills (battery-powered hammer drills) are generally more mobile than the corded varieties. This is because they don’t have power cords. So you can use them far away from a power source. Just go with extra batteries.
- Torque: The corded hammer drills tend to produce more torque than the cordless varieties. As the batteries of the cordless varieties run down, the torque produced starts to drop. The corded varieties produce the same amount of torque all through.

Choosing the Best Hammer Drills: What You Should Know
You’ve seen the differences between the cordless and the corded hammer drills.
Whichever one you’re going for you must consider the following factors when choosing the best hammer drill.
The bigger and more powerful the motor on your hammer drill is the more torque it can produce. The average motor rating is 5 amps. Most hammer drills can handle just about any task you throw at them but if you want that extra oomph, go for a drill with higher rated motor say 6 amps and above.
Drill speed control
This is important because when you drill holes in different materials you have to drill at different speeds. The speed you’d require to drill a hole in concrete is different from that required to drill holes in metals. Hammer drills with speed control option are best.
This is what holds your drill bit. The chuck needs to be very strong so as to prevent your drill bit from slipping when you work. Go for brands that have keyless chucks. Keyless chucks can be tightened with just your hand. Stay away from brands with chucks that require a tightening key as these keys are easy to lose.
If you’ve ever had to work in a dark space while holding a flashlight and your tool, then you’d consider this feature as essential as I do. Your hammer drill should come with a light that comes on when you pull the trigger.
Your hammer drill should be light weight so that you don’t get tired after prolonged use. Your hammer drill should be well balanced with easy grip. This makes the drill easier and comfortable for you to use.
Always check what material your hammer drill is made of. Hammer drills with all metal transmission are more durable. Also, hammer drills with brushless tend to last longer. This is because brush-less motors lack the wear and tear associated with their brushed counterparts.
Like we always say, a warranty is a manufacturer’s seal of trust on his product. Go for products with longer warranty as they will save you money on replacement parts should you ever need it.
You’re finally ready to check out our 5 best hammer drills out of the many we compared or tested.

Rated at 20V, the DeWalt DCD995M2 comes with two Lithium ion batteries. This hammer drill has a brushless motor and all metal transmission. A 3 setting speed trigger completes the ensemble of this drill.
The 14 electronic clutch settings on this hammer drill is one feature we’re loving. The keyless chuck on the DeWalt DCD995M2 is ½ inch and made of metal and carbide. Durability and comfort is the watch word here.
The DeWalt DCD995M2 is so light and compact at 4.7 lbs. Perfect for working in tight corners. It comes with an LED work light. This is a great addition for working in dark areas.
Another feature we love on the DeWalt DCD995M2 is the battery gauge. It conveniently lets us know the time to charge it or when it’s full. The way all the accessories fit into the carrying case is another plus.
The only downside to this hammer drill is the way the electronic clutch shuts off the motor at a pre-set limit. You have to wait a second or two to hear the click that would allow you start the drill again. A little annoying really!
The DeWalt DCD995M2 makes up for this with its amazing power and awesome feel. If you’re a contractor or serious DIYer, this is one hammer drill you must absolutely have.
2, Bosch RH540M Hammer Drill Review
Second on our list of best hammer drills is the Bosch RH540M. This is another quality product from the Bosch brand. This hammer drill will blow your mind.
The Bosch RH540M is a corded hammer drill. It comes with 6.1 ft.-lbs of torque. In hammer mode, it delivers a maximum of 2,900 BPM. It can reach up to 340 RPM in drill mode.
The Bosch RH540M is rated at 120V. It has a wide concrete range of ½ to 1 to 3/8 inches. A carrying case for all accessories is a wonderful bonus. Tool and other bits can be kept in one place for easy access.
It is designed with a keyless SDS-max chuck. The 12 position chisel rotation on the Bosch RH540M is one feature we love. This big guy can handle drilling holes in any surface ranging from tiles to wood to concrete etc.
Weighing 15.2 lbs, the Bosch RH540M is heavy. Not as light as we’d have loved. This is to be expected as this hammer drill is made of mostly metal and some plastic. Solid feel guarantees it would be durable.
One of the best features of Bosch RH540M is its service minder brushes. These little guys let you know when it’s time to get your hammer drill serviced to prevent damage: Nifty addition and very convenient too.
We loved testing out this hammer drill. The weight is the only issue we have with it. After prolonged use, you’d definitely be feeling the burn like we were.
The Bosch RH540M is a great hammer drill regardless of its heft. If you’re a contractor or a professional remodeller, this hammer drill will serve you well. Going for another would be foolhardy.

Makita brand is known for their quality power tools. The Makita XPH012 is another great product from them. And it’s third on our best hammer drill review list.

The XPH012 has a lot of amazing features and tested really well. We would have just loved a battery gauge with this hammer drill. Full charge time is a science experiment we had to perform and time.
The LED work light is great. But its location is not so great. It is located above the trigger and the drill spot in the shadow of the chuck.
The XPH012 is a great hammer drill regardless. We loved and enjoyed using it. Any serious DIYer, professional remodeller and contractor would find this little but powerful hammer drill equal to any task.
4, Bostitch BTE140K Hammer Drill Review

The one thing we didn’t like was the noise level on the DeWalt DWD520K. We wish it were quieter. In this age, everyone wants more ease and convenience when using their tools. A keyless chuck would have been nice.
