Tackling tough DIY projects often requires the right tools. For years, I struggled with less powerful drills when dealing with concrete and masonry, leading to frustration and incomplete projects. A reliable rotary hammer would have saved me countless hours and headaches.
Rotary hammer drills are indispensable for anyone working with concrete, brick, or stone. These power tools offer significantly more drilling power than standard drills, making quick work of tasks like installing anchors, hanging shelves, or even demolition. The ideal customer for a rotary hammer drill is someone who frequently works on home improvement projects, construction, or other tasks requiring drilling into hard materials. Those who only occasionally drill into softer materials like wood or metal might find a standard drill sufficient and more cost-effective. If you rarely need the extra power of a rotary hammer, investing in a versatile, high-quality standard drill would be a more prudent choice. Before purchasing, consider the power requirements for your projects, the brand’s reputation for durability, and the weight and ergonomics of the tool to ensure comfortable and efficient use.

Exploring the DEWALT DCH172B’s Key Features and Benefits
Powerful Performance
The 1.4 Joules of impact energy delivered by the DEWALT DCH172B makes light work of drilling into concrete, brick, and stone. I’ve used it for various projects, from installing heavy-duty shelving brackets to drilling holes for electrical conduit. The difference in speed and ease compared to my previous drill was immediately noticeable. This power, combined with the SDS-Plus system for quick bit changes, significantly speeds up the workflow and reduces fatigue.
Lightweight and Ergonomic Design
The DCH172B‘s lightweight design is a major plus, especially for extended use. This is crucial for overhead work or prolonged drilling sessions, preventing hand and arm fatigue. The well-placed side handle provides excellent control and stability, even when drilling at high speeds. While not perfectly balanced, the ergonomics are still superior to many competing models in its class.
Brushless Motor and Extended Runtime
The inclusion of a brushless motor is a key selling point. Brushless motors are known for their efficiency, providing longer runtimes on a single charge compared to brushed motors. This translates to less downtime and greater productivity. During my extensive use, I consistently found that the battery held up exceptionally well, even during demanding projects. This has drastically reduced the interruptions in my workflow.
SHOCKS Active Vibration Control
The SHOCKS vibration control system is a game-changer. Rotary hammers are notorious for their vibration, which can lead to discomfort and even injury with prolonged use. The DEWALT DCH172B’s SHOCKS system effectively minimizes these vibrations, making the tool much more comfortable to use, even for hours at a time. This feature significantly enhances the user experience and promotes longer working sessions without fatigue.
Versatile Mode Selector
The ability to quickly switch between drill and hammer drill modes is extremely convenient. This allows for versatile application, handling various materials with ease. I’ve used the drill-only mode for softer materials like wood, achieving clean and precise holes without damaging the surrounding surface. The seamless transition between modes is a significant time saver.
Included Accessories
The DCH172B comes with a useful set of accessories, including a belt hook, 360° side handle, and a depth rod. These are all practical additions that improve usability and overall value. The depth rod is particularly useful for ensuring consistent hole depths, which is essential in many applications.
