Caterpillar DX21B SDS-Plus Rotary Hammer (Bare Tool) 18V Brushless

The Caterpillar DX21B is a high-performance cordless SDS-Plus rotary hammer designed for professional drilling and chiseling applications. As a bare tool (battery and charger not included), it offers flexibility for users already invested in the Caterpillar 18V battery platform. Featuring a brushless motor and anti-vibration system, this tool delivers efficient power transfer and reduced operator fatigue.

Advantages

Brushless motor technology ensures longer runtime, greater durability, and more power compared to brushed motors. The anti-vibration system minimizes hand and arm strain during prolonged use. Three operating modes (drill, hammer drill, chisel) provide versatility for concrete, wood, and steel drilling, as well as light chiseling tasks. The built-in LED work light illuminates dark workspaces, and the variable speed trigger allows precise control.
