You may have drilling and chiseling projects at home that call for a rotary hammer. A rotary hammer is a versatile tool that can drill through drywall and concrete slabs. Since picking the best rotary hammer can be challenging, we’ve reviewed three great options to help you make an informed buying decision.
If you’re searching for a powerful rotary hammer that does an excellent job without making a lot of noise, this is the one. Its vibration control is easy to work with, despite pushing out 2.4 foot-pounds of impact energy.
- Three-finger trigger lets you change hammer speeds (0-4,000 bpm; 0-900 rpm)
- 360-degree auxiliary handle gives you better wrist control and flexibility
- Hammer has an integral clutch that helps reduce torque reaction
- Weighs almost 8 pounds, so if you continuously work with this hammer you’ll probably strain your arms
- You can’t use it to drill or chisel wood; you need a less powerful tool
Despite having a seven amp motor, it delivers 0-1,100 rpm and 0-4,500 rpm. You can utilize up to 40-bit angle settings to get the best performance out of this tool. It comes with a one-year warranty.
- Torque-limiting clutch helps prevent the hammer from getting damaged; it disengages the gear if the bit gets snagged
- Timed hammering during rotation reduces overlapping bit impacts, cutting drill time by 50 percent
- “Constant on” function will damage the motor or wreck the hammer if you mistakenly release it
- Hammer is very light and only ideal for small jobs
This hammer sports an 8.5 amp motor that delivers three joules of impact energy for less drilling time and more coverage. Its vibration control feature allows you to focus on intense tasks and minimizes hand fatigue.
- Uses a revolving brush ring that delivers maximum torque, whether it’s in a clockwise or counter-clockwise motion
- 360-degree side handle lets you get a better grip, so you can use it for multiple projects
- Not ideal for large-scale projects
- Corded and can only be used in places that have electricity
- Consumes a lot of power, especially when used for long periods
Why Trust Us
All of our reviews are based on market research, expert input, or practical experience with most products we include. This way, we offer genuine, accurate guides to help you find the best picks.
Benefits of Rotary Hammers
- Powerful. Rotary hammers are more powerful than other types of hammers. They have more impact energy and are ideal for tasks that require drilling large holes into hardened concrete. The hammers are similar to jackhammers, only lighter. They are better at hammering and can easily perform construction or demolition tasks.
- Different Settings. The best rotary hammers have more than one setting. You can alternate between the hammer mode, the hammer/drill mode, and the drill mode. When you choose the hammer-only mode, the device functions without rotating, which is best for light demolition work or carpentry work. A rotary hammer with different settings allows you to perform more tasks faster and with more accuracy.
- Comfortable. A rotary hammer vibrates less and offers a good grip, cushioning you from vibrations. Its adjustable front handle and large rear handle enhance its stability, allowing you to work for longer. A rotary hammer’s rate of blows is slower, but it has more powerful impacts. You exert less force and get more work done.
Types of Rotary Hammers
If you don’t work in a traditional workshop, or often move from site to site, this type of rotary hammer is best. It is portable and versatile and allows you to work without tripping over cords. When fully charged, a cordless rotary hammer can serve you the whole day. It is more compact than a corded hammer and can easily fit in tight spaces.
These are more easily available than cordless rotary hammers. However, they must be plugged into a power outlet to work. Because they have a continuous power supply, they are more powerful than cordless hammers. But they limit your movement as you work—you always have to stay close to the power. Pick a rotary hammer with a longer cord to enhance your productivity.
DeWALT is an American company renowned for its high-quality, affordable tools. It was established in 1924 and quickly launched the electric universal woodworking machine. In 1949, DeWALT Inc. was acquired by American Machine Foundry (AMF). In 1994, the company introduced over 30 cordless tools. Its Tool-Connect™ inventory management solution helps tradesmen track their tools using Bluetooth technology. The DEWALT Rotary Hammer Drill is a good example of the quality tools the company makes. It offers hand comfort and doesn’t vibrate a lot.
Founded in 1886 by Robert Bosch, this is one of the oldest tool companies. It is a German engineering company that’s popular for its unique tools and revolutionary technology, like the Fire Alarm and Voice Evacuation System. In 1912, Bosch opened a factory in Springfield, Mass., and soon started making electric tools. The Bosch electric hair trimmer was made in 1928 and the “Bosch-Combi,” an electric power tool perfect for DIY projects, was introduced in 1952. If you want a rotary hammer drill with variable speeds that comes with a carrying case, get the Bosch Bulldog Xtreme.
Mosaburo Makita launched Makita in 1915. The Japanese company has its headquarters in Aichi, Japan. It began as an electric motor repair and sales company. In 1978, Makita produced its first cordless drill. In 2004, it created brushless motor fastening tools for the defense and aerospace industries. The company has manufacturing bases for power tools and other products in Germany, China, the UK, Thailand, Brazil, and Romania. It makes powerful and durable power tools, like the Makita 3 Mode Rotary Hammer Drill.
Rotary Hammer Pricing
- $150-$250: The rotary hammers in this price range have motors that run on seven to 10 amps. They are used for light masonry and drilling into thin concrete. The impact energy delivered ranges from 1.5 to 3 ft.-lbs.
- $250 and up: These hammers have more powerful motors that deliver more impact energy—over 10 ft.-lbs. They feature ergonomic designs and are easier to work with. They can be used for longer periods and drill ¾- to 1-inch holes.
The amperage of a rotary hammer’s motor determines its power rating and the rotational speed. A higher rating means a high-performing motor that delivers more torque. A rotary hammer with a high total power output operates smoothly and efficiently, especially when performing heavy-duty tasks. The amount of power the tool can handle also affects its boring ability. Avoid a hammer with an output of fewer than six amps.
A majority of the rotary hammers on the market have two or three operation modes. Two-mode rotary hammers perform two functions: hammer drilling and rotary drilling. They are smaller in size and perfect for metal or woodworking projects. Three-mode rotary hammers are heavier and perform three functions: hammer drilling, rotary drilling, and chiseling. They can be used for a variety of projects. Multifunctional hammers have a switch that lets you choose the mode.
A rotary hammer’s motor determines its speed, and the speed is measured in blows. Rotary hammers utilize a piston mechanism instead of a special clutch. The mechanism causes them to deliver a more powerful hammer blow. The speed of the blows is measured in blows per minute (bpm), and the blows are measured in joules (J). The higher the joules, the higher the blows per minute and the quicker the hammer can drill through masonry.
Rotation and impact speed measures the rotational and translational movements the hammer makes at a given time. The rotational speed of a rotary hammer ranges between 230 and 2300 RPMs while its impact frequency lies between 2150 and 5800 beats per minute. If you want a hammer for regular home use, 1000-1500 RPMs and 4000-4500 beats per minute are ideal.
- Versatility. A versatile rotary hammer is a must-have because it can perform many tasks. A hammer with variable speeds can result in higher productivity. However, ensure yours has a speed control lock which locks the speed level and enhances your safety. A cordless compact hammer gives you easy access to tight spaces and can achieve multiple bit angles.
- Design. The best rotary hammer is easy to use, ergonomic, and can be used for long periods. Get a hammer with a feature that reduces the discomfort caused by torque reaction. It should also offer a good grip to give you better control. An ergonomic rotary hammer absorbs shocks and enhances your work’s precision.
- Accessories. Whether you’re a professional or an amateur, you need a hammer with many accessories. Accessories such as spade bits, chisel bits, or drill-specific attachments enhance your hammer’s functionality and accuracy. Some manufacturers provide safety equipment like safety masks and gloves, while others provide a carrying case, oil feeders, and wrenches.
