DEWALT Rotary Hammer Drill DCH172B Review Powerful Lightweight Cordless Performance

Description

Highlights of the DEWALT 20V MAX SDS Plus Rotary Hammer Drill

Testing the DEWALT 20V MAX SDS Plus Rotary Hammer Drill, Cordless, 5/8 in., Tool Only (DCH172B) has been quite an interesting journey. Its brushless motor and the German-engineered mechanism truly stand out, delivering powerful performance with 1.4 joules of impact energy that punches through concrete and masonry like a pro. The lightweight and compact design makes it a breeze to handle, especially in tight spaces where bigger tools just won’t fit. I found it particularly useful for tasks like rod hanging, concrete forming, cable tray mounting, and strut mounting—all jobs that require both precision and power.

The variable speed control adds a nice touch of versatility, allowing me to adjust the drilling speed depending on the material. Switching between drill and hammer drill modes is effortless thanks to the mode selector switch, which saved me time during different parts of my project. What impressed me the most was the vibration control handle equipped with SHOCKS active vibration control system; it noticeably reduced fatigue and hand strain during prolonged use. This feature alone makes a huge difference for anyone who’s tired of the usual jarring feeling that comes with rotary hammers.

Price to Quality Ratio

Considering its cordless convenience and solid build, this rotary hammer drill offers a pretty compelling price to quality ratio. It’s not the cheapest on the market, but the brushless motor and durability you get here justify the investment. Compared to some other cordless rotary hammers, this one feels like a long-term companion rather than a disposable gadget. The battery compatibility with other 20V MAX tools from the same brand adds great value, too, allowing me to swap batteries seamlessly without owning multiple chargers or packs.

It’s important to note that the tool is sold as tool only, so you’ll need to factor in the cost of batteries and charger if you don’t already own compatible ones. For anyone already invested in the brand’s ecosystem, this makes perfect sense and keeps things modular. In terms of energy efficiency, the brushless motor helps extend runtime, meaning fewer battery swaps and less downtime. All in all, this tool delivers a solid bang for the buck if you’re after cordless mobility without compromising on power.

Shortcomings You Should Know About

Despite its many perks, the rotary hammer drill isn’t without flaws. The depth rod included might feel a bit flimsy compared to others I’ve seen in similar tools, and sometimes it’s a bit tricky to keep it perfectly aligned during drilling. Also, the maximum chuck size of 1 inch is standard but could limit some users who prefer bigger bits for heavy-duty demolition.

The weight of 4.6 pounds is lightweight for this category, but the balance sometimes feels a little off, especially when working overhead or in awkward positions. I also noticed the battery capacity at 2 amp hours means you might need to carry a spare battery for longer jobs, which adds some extra weight to your kit. Noise levels during operation are typical for rotary hammers, but if you’re sensitive to loud tools, ear protection is a must.

Benefits That Make It Worthwhile

There’s a lot to appreciate about this rotary hammer drill beyond its power. The ergonomic design with a 360-degree side handle helps maintain control and stability, which is crucial when drilling into tough materials. The keyless chuck means bit changes are quick and painless, saving precious time during work. I was also impressed by the reverse rotation option, useful for removing stuck bits or screws without switching tools.

OSHA compliance is a big deal for professionals, and pairing this tool with the right dust extraction accessories keeps your workspace cleaner and safer. The compact size makes it ideal for both professional contractors and DIY enthusiasts who need a reliable, portable tool. Its versatility across different materials like wood (up to 26 mm) and metal (up to 13 mm) adds to its practicality.

• Brushless motor for longer runtime and durability
• Active vibration control reduces fatigue
• Versatile mode selector for drill and hammer functions

Areas for Improvement to Consider

No tool is perfect, and this one has its share of areas for improvement. The lack of included batteries and charger can be a hurdle for first-time buyers, adding to the overall cost unexpectedly. The depth rod’s alignment issues could be frustrating during precision work, demanding extra attention to detail. Additionally, the handle grip, while effective at vibration control, might feel a bit bulky for users with smaller hands.

Another point to ponder is the limited impact energy of 1.4 joules, which is great for lighter-duty tasks but may struggle with very dense concrete or heavy demolition jobs. Some users might find the maximum rotational speed of 1100 RPM on the lower side compared to industrial-grade rotary hammers. These factors don’t necessarily disqualify the tool but highlight that it’s best suited for medium-duty applications rather than extreme heavy-duty use.

• Requires additional purchase of batteries and charger
• Depth rod alignment can be tricky
• Limited impact energy for heavy demolition tasks

Product Comparisons

Comparing this rotary hammer drill with popular competitors like the Makita XRH01Z and Bosch GBH18V-26F reveals some interesting contrasts. The Makita offers slightly higher impact energy and a more robust build, making it a favorite for heavy-duty professionals. However, it’s bulkier and heavier, which can be a drawback in tight spaces where maneuverability matters.

Bosch’s model boasts excellent vibration control and dust management but comes at a noticeably higher price point. The DEWALT drill shines in weight and size, offering superior portability and convenience for lighter to medium tasks. Its brushless motor and variable speed are on par with these rivals, but it doesn’t quite hit the same power marks for hardcore demolition. For a user like me who tackles a variety of projects, this tool feels like the sweet spot between power, mobility, and price.

Handling and Usability Insights

Using this tool on various materials demonstrated its ease of handling and intuitive controls. The belt hook and included 360-degree side handle helped me maintain comfort during longer work sessions. I appreciated the variable speed trigger, which made controlling the drill’s pace effortless, especially on delicate surfaces. The compact dimensions (11.5″ L x 8.54″ W x 4″ H) make it easy to carry around, fitting well into my tool bag.

A coworker commented on how the vibration control made a noticeable difference during our joint project, reducing hand numbness after hours of drilling. The reverse function also came in handy when a bit got stuck in a stubborn anchor. While the tool-only package means you need to prepare your battery setup, this approach keeps the unit lightweight and affordable for those who already own compatible batteries.

Versatility Across Job Types

This rotary hammer drill excels in a wide range of applications. Whether it’s cable tray mounting, clip and bracket installation, or railing mounting, the tool’s power and control get the job done efficiently. It handles drilling through concrete, wood, and metal with relative ease, making it a versatile addition to any toolbox.

The brushless motor not only boosts efficiency but also extends the tool’s lifespan by reducing wear and tear. Switching between modes is quick, which means fewer interruptions for tool changes. The cordless design freed me from hunting for power outlets or tripping over extension cords—a huge plus during outdoor or remote jobs. However, for intense, continuous heavy-duty drilling, a corded alternative might still be better suited.

Testing this rotary hammer drill showed me it’s a solid tool for professionals and serious DIYers who prioritize cordless convenience, manageable weight, and reliable power. Though it has room to grow in impact strength and accessory inclusion, its smart design and thoughtful features make it a dependable choice for many applications.
