Rotary Hammer DeWALT DCH273H2T-QW 18V Brushless 2.6J

The DeWALT DCH273H2T-QW 18V Brushless 2.6J rotary hammer is a compact cordless tool designed for drilling and chiseling in concrete, masonry and other hard materials. Equipped with an 18V brushless motor that delivers 2.6 joules of impact energy, this rotary hammer balances power and portability for professional and DIY applications. The tool’s lightweight construction and ergonomic design aim to reduce user fatigue during prolonged use while maintaining reliable performance on demanding tasks.

Advantages

The brushless motor increases efficiency and reduces maintenance needs compared with brushed alternatives, providing longer runtime and improved motor life. At 2.6 J impact energy, the hammer offers sufficient force for standard concrete drilling and light chiselling while remaining compact and easier to manoeuvre in tight spaces. The cordless 18V platform gives the freedom to work without a power cable, and the lightweight design supports extended use with less strain on the operator.

Suitable for

• Drilling holes in concrete and masonry for anchors and fixings
• Light to medium chiselling and removal of plaster or tiles
• Work on construction sites where portability is required
• General renovation and maintenance tasks involving hard materials

Key specifications

• Power system: 18V brushless motor
• Impact energy: 2.6 joules
• Functionality: rotary drilling and chiselling modes
• Design: compact, lightweight and ergonomic housing for reduced fatigue
• Compatibility: attaches to standard SDS-plus bits

How to use

Select an appropriate SDS-plus bit for the diameter and task, secure the bit in the tool’s chuck according to the manufacturer’s instructions, and choose the required operating mode (rotary or hammer/rotation or chiselling) using the mode selector. When drilling, mark the drilling point, position the bit perpendicular to the surface, apply steady pressure and start at low speed if available to create a guide hole before increasing power. For chiselling, set the tool to the chisel mode, adopt a stable stance, and use controlled blows while maintaining a secure grip. Always use suitable personal protective equipment such as eye protection, hearing protection and gloves.

Usage recommendations

For best results and prolonged tool life, use DeWALT-recommended SDS-plus bits and batteries from the same voltage platform, avoid forcing the tool by applying excessive pressure, and allow the motor to cool during heavy continuous operation. Regularly inspect and clean the bit and chuck area to prevent debris buildup and maintain consistent performance.
