CAT DX21 18V 4.0Ah Cordless Brushless Professional SDS-Plus Rotary Hammer / Breaker (Two Batteries, 2.2 J)

• 18V Li‑ion battery and brushless motor technology for higher power and performance. • Designed for professional applications such as impact drilling, non-impact drilling and chiselling; brushless motor and robust gearbox deliver strong performance even in demanding concrete work. • Patented IMPULSE technology: by half-pressing the trigger during drilling or chiselling, sends a pulsed impact current from the battery to the motor to safely drill or chip oval or slippery surfaces (metal pipe, ceramic, glass) without damaging the material. • With external chuck fitted and in screwdriving mode, IMPULSE creates pulsed torque to ensure screws are fully driven on hard surfaces. • IMPULSE technology reduces bit slip when the trigger is pressed lightly in chisel or impact-drilling mode, allowing precise chiselling or drilling on delicate surfaces. • CAT 1 FOR ALL Li‑ion battery system: any 18V CAT battery operates all 18V CAT cordless tools. • CAT brushless motor technology provides up to 50% longer run time and up to 25% more power. • CAT brushless motor technology offers up to 10 times longer service life compared to competitors. • Brushless motor reduces internal friction, extending runtime and tool lifetime. • Brushless motor improves efficiency and extends operating time. • CAT 18V Li‑ion professional battery technology includes a heat shield to protect cells from excessive temperatures, prolonging battery life, enabling longer use and faster charging. • CAT 1 FOR ALL professional batteries are advanced Li‑ion batteries. • 18V 4.0Ah high-capacity brushless battery (two batteries included).
