DEWALT 20V MAX Rotary Hammer Drill Review Compact and Powerful Tool Performance

Description

Compact Design and Build Quality

The DEWALT 20V MAX SDS Plus Rotary Hammer Drill (DCH172B) is impressively compact and lightweight, weighing just 4.6 pounds. As someone who constantly moves between tight spaces and awkward angles, the compact design feels like a blessing. The tool fits snugly in hand, and the brushless motor, combined with its German-engineered mechanism, exudes both durability and efficiency. With dimensions of 11.5″ x 8.54″ x 4″, this drill is perfect for tasks like rod hanging and railing mounting, where maneuverability is everything. The classic black-and-yellow color scheme adds a professional touch, but it’s the robust build that truly stands out during use.

Performance and Impact Energy

The performance of this rotary hammer drill is one of its key benefits. Generating 1.4 joules of impact energy, it makes quick work of concrete drilling and demolishing tasks. I tested this on a concrete wall, and it glided through effortlessly without any noticeable lag. The variable speed feature was a highlight, allowing me to adapt to different materials and tasks. Coupled with 1100 RPM maximum rotational speed, this drill shows off some serious power for its size. It’s ideal for professionals and DIY enthusiasts looking for a cordless option that doesn’t compromise on performance, even for demanding tasks.

Favorable Aspects

• Lightweight and compact, making it easy to handle in tight or overhead spaces.
• Brushless motor ensures efficient runtime and reliable performance.
• Delivers 1.4 joules of impact energy, perfect for fast concrete drilling.
• Variable speed settings offer adaptability for different applications.

Vibration Control and Comfort

The SHOCKS active vibration control system is a standout feature here. I used this on several projects, and the reduced vibration at the handles made a noticeable difference. After extended use, I wasn’t left with the hand fatigue that often comes with traditional rotary hammers. This feature alone makes it worth considering for anyone who spends long hours on drilling tasks. The inclusion of a 360° side handle and depth rod further enhances usability, allowing for precise and comfortable operation.

Limitations to Consider

While this tool impressed me in many areas, there are a few less favorable aspects worth mentioning:

• No battery included in the package, which adds an additional purchase for first-time buyers.
• The 5/8-inch drilling capacity may not suffice for larger industrial applications.
• It lacks a dedicated carrying case, which would have been helpful for storage and transport.

These aren’t deal-breakers, but they’re worth keeping in mind depending on your needs.

Mode Selector and Versatility

Switching between drill and hammer drill modes is seamless thanks to the mode selector switch. During testing, I transitioned from drilling into wood to hammering into concrete without any hiccups. The reverse rotation feature was particularly useful for removing stuck drill bits, saving both time and frustration. This versatility makes the rotary hammer suitable for a range of tasks, from cable tray mounting to heavy-duty concrete forming.

Competing Products

In comparison to other cordless rotary hammers in its class, this one holds its ground well. For instance, the Makita XRH04Z offers slightly more impact energy but lacks the excellent vibration control of the DEWALT model. Meanwhile, the Bosch GBH18V-20N is another strong contender with similar performance, yet it doesn’t feel as lightweight or ergonomic in extended use. If you prioritize portability and reduced vibration, this tool is a clear winner.

Cost Efficiency

When evaluating the price-to-quality ratio, this rotary hammer feels like a sound investment. The durable build, combined with the powerful performance, justifies the cost for professionals who need a reliable and versatile tool. While the additional expense of batteries might seem like a downside, the long-term cost efficiency of the brushless motor makes up for it. For anyone looking to balance affordability with high performance, this tool is hard to beat.

This drill has proven itself as a capable and well-rounded tool, particularly for tasks in tight spaces. It’s not perfect, but its lightweight design, vibration control, and easy-to-use features make it a strong contender in the cordless rotary hammer category.
