10 Best Rotary Hammers 2025 in the United States

The DEWALT 60V MAX Cordless Hammer Drill is a powerful and versatile tool designed for medium to heavy-duty concrete drilling and chipping. With an impact energy of 6.1 Joules and a brushless motor, it efficiently handles tough materials like concrete and rebar, making it suitable for contractors and serious DIYers. Its cordless design with two included FLEXVOLT batteries offers good portability, allowing work in areas without easy access to power outlets.

The drill maintains a constant speed of up to 1100 RPM, which is decent but not the fastest in its class. It includes DEWALT’s SHOCKS Active Vibration Control system, reducing hand fatigue during long jobs, a significant comfort feature. Weighing nearly 12 pounds, it’s somewhat heavy, so extended overhead use might be tiring. The 20mm chuck size is standard and compatible with common drill bits, and the anti-rotation E-CLUTCH helps prevent tool damage if the bit gets stuck.

Its drilling capacity is good for metal and wood, with an emphasis on horizontal drilling for rebar and coring up to 3 inches. Additionally, the tool is tag-ready with an app for easy tracking, a useful feature in busy job sites. While it lacks variable speeds beyond one setting, its power and vibration control make it a solid choice for users needing a cordless rotary hammer for moderate to heavy work. If portability and reduced vibration are priorities, this DEWALT model is a strong contender, though users should be prepared for its weight during prolonged use.

The DEWALT DCH775X2 is a powerful cordless rotary hammer designed for heavy-duty concrete drilling and chiseling tasks. With 13.3 joules of impact energy, it delivers strong blows that make quick work of tough materials like hard concrete and rebar. Its 60V battery system and brushless motor provide efficient performance and longer runtime without the hassle of cords. The tool operates at a moderate speed of 290 RPM, which is suitable for controlled drilling and chipping in construction or renovation work.

The SDS MAX chuck type supports bits up to 2 inches, allowing for versatile drilling and coring applications, including dry coring up to 6 inches deep. It weighs about 40.7 pounds, which is on the heavier side, but this weight helps balance the tool during horizontal and downward drilling, making it stable for rebar dowel work. While it doesn't specifically mention advanced vibration control, the design of this midweight tool helps reduce user fatigue compared to heavier models.

The kit includes two 9Ah FLEXVOLT batteries and a fast charger, which means less downtime and more continuous work. Variable speed control is another plus, giving you more precision depending on the task. The relatively low maximum rotational speed and heavier weight might be less ideal for users needing extremely fast or highly portable tools. This DEWALT rotary hammer fits well for professionals or serious DIYers who require strong impact power and cordless convenience for demanding concrete work. It may be more than necessary for light or occasional drilling but excels in durability and consistent performance on tough jobs.

The DEWALT 20V MAX SDS Rotary Hammer Drill (DCH273B) is a strong contender in the rotary hammer category, particularly suited for users who need a reliable tool for concrete drilling and installation tasks. With 2.1 Joules of impact energy, it provides impressive drilling power, making it effective for various applications such as rod hanging and rail mounting. Its brushless motor contributes to efficient performance and longer runtime, which is a significant plus for demanding jobs.

One of the standout features is the SHOCKS ACTIVE VIBRATION CONTROL system, which significantly reduces the vibration felt in the handles. This feature is ideal for prolonged use, as it enhances user comfort and reduces fatigue, especially when working on larger projects. Weighing in at just 6.4 pounds, it's lightweight for a rotary hammer, allowing for better maneuverability and less strain during use. The cordless design adds convenience, eliminating the hassle of cords getting in the way, which can be a major advantage in tight spaces or outdoor settings.

There are a few drawbacks to consider. The power output at 20 watts is relatively low compared to some competitors, which may limit its performance on tougher materials. Additionally, since this is a bare tool, you will need to purchase the battery and charger separately, which can add to the initial investment. The DEWALT DCH273B is an excellent choice for DIY enthusiasts and professionals seeking a lightweight, comfortable, and versatile rotary hammer for everyday tasks, though those needing more power should explore other options.
