10 Best Rotary Hammer Drills 2025 in the United States

The DEWALT 20V MAX SDS Plus Rotary Hammer Drill (DCH133B) is a cordless tool designed for various construction and installation tasks. With 2.6 Joules of impact energy, it delivers efficient performance, especially when drilling into concrete. This is facilitated by its brushless motor and durable German-engineered mechanism, which together ensure longer runtime and reduced maintenance needs. The lightweight design enhances portability, making it suitable for tasks like rod hanging, structural connections, and mounting jobs.

A notable feature is the rotating dial, allowing you to switch between Drill, Hammer Drill, or Chip modes, catering to different project requirements. The tool operates at a maximum speed of 5550 RPM, which is adequate for most drilling tasks. Additionally, its 20V battery power source provides the convenience of mobility without being tethered to a power outlet.

However, there are some considerations to note. Being a 'bare tool,' it does not come with a battery or charger, which means additional purchases are necessary if you don’t already have DEWALT 20V batteries. While its 4 Amp motor is efficient, it might not match the raw power of some corded models, especially for more demanding tasks. Additionally, this model may lack advanced vibration control features, which could lead to user fatigue during extended use.

The inclusion of a 360° side handle and depth rod adds to its utility, assisting with stability and precision. This DEWALT rotary hammer is best suited for users who need a reliable, portable tool for moderate-duty tasks and are already invested in the DEWALT 20V ecosystem.

The DEWALT 20V MAX SDS Rotary Hammer Drill, model DCH273B, is designed for both professionals and DIY enthusiasts looking for a cordless solution for heavy-duty drilling tasks, particularly in concrete. With an impact energy of 2.1 Joules and a maximum power of 300 watts, it provides solid performance, making it effective for various applications like rod hanging and cable tray mounting. The lightweight design, at just 6.4 pounds, enhances portability, allowing users to work comfortably over extended periods.

One of its standout features is the SHOCKS ACTIVE VIBRATION CONTROL system, which significantly reduces the vibration felt in the handles, a great advantage for user comfort during prolonged use. Additionally, the brushless motor contributes to its efficiency and longer runtime, which means less frequent battery changes. The three application modes—Drill, Hammer Drill, and Chip—offer flexibility depending on the task at hand.

There are a few considerations to keep in mind. The drill is a bare tool, meaning it does not come with a battery or charger, which may be an extra cost for those who do not already own compatible DEWALT products. Also, while the 2800 RPM speed is impressive, it might not be as powerful as some corded options available in the market, which could be a drawback for extremely heavy-duty tasks. In conclusion, the DEWALT DCH273B is a reliable and versatile rotary hammer drill well-suited for both casual and more serious users in need of a portable, efficient tool for concrete drilling, but potential buyers should be aware of the additional costs associated with battery and charger purchases.

The Hilti 2063000 Combihammer TE 70-AVR is a robust rotary hammer drill designed for professionals who need serious drilling and chiseling performance. With a powerful 120V corded electric motor, it delivers impressive impact energy, making it suitable for heavy-duty tasks in construction or renovation projects. The durable construction ensures longevity, which is a significant advantage for frequent users, as it can endure tough job site conditions. Additionally, the quick-release chuck allows for swift bit changes, enhancing productivity on the job.

One of its standout features is the lower vibration design. This not only improves user comfort but also helps to maintain accuracy during extended use, reducing fatigue—a key factor when using a heavy tool like this. The integrated theft protection adds peace of mind, particularly for those working in public or shared spaces.

At 26.79 pounds, this drill is on the heavier side, which might be challenging for some users, especially during prolonged use. Its size and weight can make it less portable for smaller tasks or residential use, where lighter tools might be preferable. The power source being corded means you will need access to electrical outlets, limiting mobility compared to battery-operated options. If you are a professional tradesperson looking for a reliable and powerful rotary hammer drill for demanding jobs, the Hilti TE 70-AVR is an excellent choice.
