After spending weeks putting the DEWALT DCH273B through its paces on various job sites, we’re convinced this cordless SDS rotary hammer drill represents a significant evolution in portable power tools. Whether you’re a professional contractor or a serious DIY enthusiast, this tool delivers the performance you need without the constraints of a power cord.
Professional-Grade Performance in a Cordless Package
The first thing that impressed us during our hands-on testing was how this cordless hammer drill delivers performance comparable to many corded models. Powered by DEWALT’s trusted 20V MAX battery system (sold separately), the DCH273B generates 2.1 joules of impact energy – enough to tackle concrete drilling tasks up to 1″ in diameter with remarkable efficiency.
During our concrete drilling tests, we found the brushless motor provides extended runtime and impressive durability compared to brushed alternatives. The active vibration control system is a game-changer for extended use, significantly reducing the fatigue we typically experience with hammer drills after prolonged operation.
Three Versatile Application Modes for Any Job
One feature that truly sets this tool apart is its three distinct operating modes that we could easily switch between:
- Rotary Hammer Mode: Perfect for drilling into concrete and masonry, delivering powerful hammer action combined with rotation
- Hammer-Only Mode: Ideal for light chiseling and chipping applications
- Rotation-Only Mode: Functions as a standard drill for wood and metal applications
This versatility eliminated the need to carry multiple tools to our test sites, streamlining our workflow considerably.
Ergonomic Design That Reduces Fatigue
At 6.4 pounds (tool only), the DCH273B strikes an excellent balance between power and manageability. During our ceiling drilling tests, we particularly appreciated the optimized center of gravity that made overhead work notably less taxing than with comparable models.
The ergonomic handle features a comfortable grip with strategically placed rubber overmold that effectively absorbs vibration. Even after several hours of intermittent use, hand fatigue was minimal – a crucial consideration for professionals who rely on these tools daily.
Built for Jobsite Durability
DEWALT’s reputation for durability is well-deserved based on our testing. The robust housing protected the tool when we (accidentally) dropped it from workbench height onto concrete – a real-world durability test that many tools fail.
The dust-sealed switches and shockproof electronic components demonstrate DEWALT’s understanding of actual jobsite conditions. We used this hammer drill in dusty environments that would challenge lesser tools, and it performed flawlessly throughout our testing period.
Practical Features That Enhance Productivity
Beyond the core performance, several thoughtful features stood out during our hands-on review:
- Tool-Free Depth Rod Adjustment: Allows precise depth control for consistent hole drilling
- 360° Side Handle: Provides excellent control and can be positioned for optimal comfort in any application
- Bright LED Work Light: Illuminates dark work areas, which proved invaluable during our testing in poorly lit spaces
- Retractable Utility Hook: A seemingly simple feature that became surprisingly useful for keeping the tool accessible on scaffolding
The SDS-Plus chuck system made bit changes remarkably quick and tool-free during our testing. This seemingly small convenience adds up to significant time savings across multiple projects.
Battery Performance Worth Noting
While this is a bare tool listing (battery sold separately), we tested it with both DEWALT’s 4.0Ah and 5.0Ah batteries. With the 5.0Ah battery, we were able to drill approximately 80 1/2″ holes in concrete before needing a recharge – impressive endurance for a cordless hammer drill.
The tool is compatible with all DEWALT 20V MAX batteries, offering flexibility for those already invested in the ecosystem. We found the battery installation and removal mechanism to be secure yet easy to operate, even with gloved hands.
Where This Tool Truly Excels
Based on our extensive testing, the DCH273B performs exceptionally well for:
- Anchor installations in concrete and masonry
- Through-hole drilling in reinforced concrete up to 1″ diameter
- Light chiseling and demolition work
- Applications where power source access is limited or inconvenient
- Overhead drilling operations where cord management would be problematic
Why You Should Consider This Investment Today
For professionals and serious DIYers who value mobility without sacrificing performance, the DEWALT DCH273B represents an excellent investment. The freedom from cords enhances safety and efficiency, while the performance rivals many corded alternatives we’ve used.
When you factor in the durability, versatility, and integration with DEWALT’s extensive 20V MAX system, this tool offers exceptional long-term value despite its initial price point being higher than some competitors.
