Who it fits

Key specs explained

Impact Energy: 2.1 Joules

This value measures the force delivered to the bit per strike. Higher joules mean faster penetration into hard materials like concrete or masonry. You benefit from reduced drilling time on tough jobs. When comparing kits, look for tools with at least this energy level for serious masonry work. Lower values may struggle with dense materials.

Motor Type: Brushless

A brushless motor lacks carbon brushes, reducing friction and wear. This design typically offers longer runtime and greater durability than brushed alternatives. You get more consistent power as the battery drains. Compare this feature when selecting kits, as brushless motors often justify a higher initial investment through extended tool life and efficiency.

Weight: 6.4 lbs.

This is the total weight of the bare tool. A lighter tool reduces user fatigue during overhead work or extended use. You can maneuver it more easily in tight spaces. When evaluating combo kits, consider how weight affects your comfort. Heavier tools may offer more power but require more strength to control for long periods.

Bit System: SDS

SDS refers to a specific shank type for drill bits. It allows for faster bit changes and better torque transfer compared to standard chucks. You benefit from secure bit retention during high-impact drilling. When shopping for kits, ensure compatibility with SDS bits. This system is standard for rotary hammers used in masonry applications.

Design and build details

According to the listing, the DEWALT DCH273B measures 13 inches in length, 4.2 inches in width, and 8.6 inches in height. These dimensions define its physical footprint. The tool weighs 6.4 pounds. This mass balances portability with the durability needed for construction sites. You can maneuver it in tight spaces, such as when installing rod hangers or seismic attachments. The compact form factor supports overhead work without excessive fatigue.

The handle layout incorporates DEWALT’s SHOCKS Active Vibration Control system. This feature reduces the vibration felt at the handles compared to rotary hammers lacking this technology. Less vibration improves control during prolonged use. The rotating dial allows you to switch between three application modes: Drill, Hammer Drill, or Chip. This mechanical interface lets you select the correct operation for the material without fiddling with digital menus. The brushless motor and German-engineered mechanism are housed within a durable casing designed for efficient performance.

Finish and color are listed as multi, indicating standard industrial markings for visibility. The SDS bit system secures masonry bits firmly. This connection type ensures torque transfer is direct and reliable. The bare tool design means you supply your own 20V MAX battery. This allows you to use existing power sources from your DEWALT ecosystem. The overall build prioritizes function over aesthetics, fitting the demands of professional masonry and structural mounting tasks.

Setup and everyday use

You must pair this bare tool with your own 20V MAX battery. The listing confirms no battery is included. This setup step is standard for bare tools. You select a compatible 20V battery from your existing DEWALT collection. Once powered, the brushless motor engages. This motor type offers efficient performance and longer runtime compared to brushed alternatives. The German-engineered mechanism drives the internal components. This design supports durable operation during heavy use.

Daily use begins with mode selection. A rotating dial lets you choose between three specific application modes. You can set the tool to Drill, Hammer Drill, or Chip. This dial allows quick changes without switching tools. The SDS bit system accepts standard SDS-plus bits. This interface ensures secure bit retention during high-impact drilling.

The tool includes SHOCKS ACTIVE VIBRATION CONTROL. This system reduces vibration felt at the handles. This feature contrasts with rotary hammers lacking this technology. Reduced vibration helps maintain control during extended periods of use. The 2.1 Joules of impact energy provides consistent force for concrete. This energy level supports fast drilling speeds. The 6.4-pound weight aids in handling. It balances portability with the mass needed for effective hammering. You can use it for rod hanging, seismic attachments, or cable tray mounting. When paired with the DWH303DH On Board Extractor, it meets OSHA Table 1 compliance. This combination helps manage dust during masonry work.

Before You Buy This Tool

Since this is a bare tool, you need a compatible 20V MAX battery to operate it. Ensure your existing battery fits the tool’s power requirements. The SDS bit system is standard for masonry work, so verify your bits match this interface. Regular maintenance includes cleaning the chuck and checking the vibration control system. This tool fits well in kits where you already own DEWALT batteries. It complements other cordless tools by offering specialized rotary hammer capability. If you frequently drill into concrete, this 2.1 joule impact energy is efficient. However, if you only need light drilling, a standard drill might suffice. Check the weight and size for your specific tasks. The rotating dial allows you to switch between modes easily. This flexibility makes it suitable for various construction applications. Always follow safety guidelines when using power tools.

Check before you buy

• Verify you have a compatible 20V MAX battery
• Confirm SDS bit compatibility for your masonry work
• Check if the weight suits your task needs
• Ensure you have an extractor for OSHA compliance
