The DEWALT 20V MAX SDS Rotary Hammer Drill (DCH273B) is a versatile and powerful tool ideal for various applications like rod hanging, seismic & safety attachments, cable tray & strut mounting, clamp mounting, and rail mounting. One of its prominent strengths is its cordless design, offering the convenience of portability without being tethered to a power outlet. It delivers 2.1 Joules of impact energy, making it effective for fast drilling in concrete and other tough materials.
The brushless motor and German-engineered mechanism contribute to its efficient performance and longer runtime. Weighing just 6.4 pounds, it is relatively lightweight, reducing user fatigue during extended use. The SHOCKS ACTIVE VIBRATION CONTROL System is another significant advantage, as it minimizes the vibration felt by the user, enhancing comfort and control during operation. It also features a rotating dial that allows users to switch between Drill, Hammer Drill, and Chip modes, adding to its versatility.
However, there are some drawbacks to consider. The tool is sold as a bare unit, meaning batteries and a charger are not included, which could be an additional expense. Additionally, while it is battery-powered, the runtime will depend on the battery capacity, potentially requiring frequent recharges or spare batteries for longer tasks. Despite these minor inconveniences, the DEWALT 20V MAX SDS Rotary Hammer Drill is a high-performing tool, well-suited for both professional and DIY users looking for a reliable and powerful cordless drill.
The Bosch 11264EVS 1-5/8 Inch SDS-Max Combination Hammer is a powerful and versatile tool ideal for heavy-duty tasks. With its 13.0 amp motor and 6.5 ft.-lbs. of impact energy, it offers excellent performance, especially in hammer-only mode where it delivers 20% more power. This makes it a strong contender for tasks that require significant force. The maximum rotational speed of 340 RPM might not be the highest, but it is sufficient for most heavy-duty drilling and hammering applications.
Weighing 15.2 lbs., the tool is relatively lightweight considering its power, which can help reduce user fatigue during prolonged use. The corded electric power source ensures consistent performance without the need for battery changes or recharges, though it does limit mobility to some extent. The SDS-Max chuck allows for quick and secure bit changes, enhancing productivity on the job site.
One standout feature is Bosch’s Active Vibration Control, which significantly reduces vibration and improves user comfort, making it suitable for extended use. Additionally, the dual-mode selector provides the versatility to switch between rotary hammer and hammer-only modes based on the task at hand. Bosch’s Constant Response Circuitry further ensures consistent speed under load and provides overload protection and smooth starts. The tool-free SDS max bit system, automatic bit-locking, and maximum impact energy transfer rate are convenient features that enhance its usability and efficiency. This tool is best suited for professionals or serious DIY enthusiasts who need a reliable and powerful hammer drill for demanding applications.
The DEWALT 60V MAX Cordless Hammer Drill Kit is a powerful and versatile tool designed for heavy-duty drilling and chipping, especially in concrete and masonry. With 6.1 Joules of impact energy, it delivers strong blows that make quick work of tough materials. The cordless design, powered by two FLEXVOLT lithium-ion batteries, offers the freedom to work without being tied to an outlet, which is great for job sites or places without easy access to power. It weighs about 12 pounds, which is reasonable for a tool with this power, and the lightweight design helps reduce fatigue during horizontal drilling tasks. The drill operates at a maximum speed of 1100 RPM, controlled by variable speed electronics that maintain steady performance even under heavy load. Its 20mm chuck size fits standard SDS bits and supports a variety of drilling jobs.
Notably, the drill includes advanced features like an Anti-Rotation E-CLUTCH that protects you if the bit binds, and SHOCKS Active Vibration Control, which makes long periods of use more comfortable by reducing handle vibration. The brushless motor and German engineered mechanism contribute to durability and efficiency. The drill is heavier compared to some smaller SDS drills, which might be a consideration if you need a more compact tool for overhead work. While the impact energy is strong, some professional-grade rotary hammers offer even more power for extremely tough concrete. The inclusion of DEWALT's Tool Connect system is a plus for easily tracking your tool on a busy site. This drill suits contractors and serious DIYers looking for a robust cordless SDS hammer drill that balances power, convenience, and smart features.
