Advantages

The DCH274P2T offers cordless convenience while maintaining the performance expected from a compact rotary hammer. Its 400 W motor and 2.1 J impact energy provide sufficient power for drilling masonry and concrete up to the specified 24 mm diameter. With a moderate weight of 3.3 kg and a compact footprint (85 mm width, 328 mm depth), the tool is easier to handle in confined spaces. Vibration emissions of 6.6 m/s² and a noise level of 97 dB are specified to help assess user comfort and required protective measures.

Suitable for

• Drilling holes in concrete, brick and masonry up to 24 mm diameter

How to use

Fit a compatible SDS drill bit or chisel into the tool’s chuck according to manufacturer instructions and secure the battery before operation. Select the appropriate mode if the tool offers drilling or hammering settings, then position the bit at the intended drilling point. Apply steady, moderate pressure and allow the tool’s hammering action to do the work; avoid excessive force that could stall the motor. After finishing, turn off the tool, remove the battery, and clean the bit and tool housing to remove dust and debris.

Recommendations

Use appropriate personal protective equipment such as eye protection, hearing protection and gloves. For extended work sessions, consider vibration-damping accessories and plan regular breaks to reduce hand-arm vibration exposure. Observe the specified drilling diameter and impact energy limits and follow local safety regulations regarding noise and dust control.
