Description
The CAT DX21 rotary hammer with a powerful brushless motor delivers high power and reliability. This mid-range tool is equipped with an SDS-Plus quick-change chuck for easy bit replacement without long work interruptions.

The CAT DX21 device, featuring a rubberized body, an auxiliary handle for better support, and an anti-vibration system, prevents hand fatigue even when held in uncomfortable positions. The system is complemented by reverse mode, bright illumination, a drilling depth stop, and protection against accidental start. The tool comes in a convenient storage case with two replaceable batteries and a charger, an auxiliary handle, and a depth stop.
