BOSCH Bulldog Xtreme 11255VSR 1-Inch SDS-Plus Rotary Hammer Drill – 8 Amp Corded Concrete & Masonry Hammer with 3 Modes and Carrying Case
Overview
The BOSCH Bulldog Xtreme 11255VSR Rotary Hammer is a professional-grade 1-inch SDS-Plus hammer drill designed for demanding concrete, masonry, drilling, chiseling, and demolition applications. Powered by a robust 8-amp motor, this versatile corded rotary hammer delivers powerful impact energy and multiple operating modes to tackle a wide range of jobsite tasks.
Featuring Bosch's SDS-Plus bit system, the Bulldog Xtreme allows fast, tool-free bit changes while maximizing impact energy transfer. The multi-function selector provides three operating modes—rotation-only, rotary hammer, and hammer-only—giving users the flexibility needed for drilling anchor holes, chiseling concrete, removing tile, and other construction tasks.
Built for durability and user comfort, the tool incorporates vibration control technology, a D-handle design, an integral clutch, and Bosch's Vario-Lock system with 36 chisel positions for optimized working angles.

Why It Stands Out
The BOSCH Bulldog Xtreme 11255VSR has earned a reputation as one of the most trusted SDS-Plus rotary hammers among contractors and tradespeople. Its combination of powerful impact performance, versatile operating modes, and durable Bosch engineering makes it suitable for both drilling and light demolition applications.
Unlike standard hammer drills, the SDS-Plus rotary hammer mechanism delivers significantly greater impact efficiency in concrete and masonry. Features such as Vario-Lock positioning, vibration control, and the integral clutch help improve comfort, productivity, and safety during extended use.
