Unleash Legendary Power with the Ultimate Multi-Mode Concrete Rotary Hammer

Dominate your job site with the Bosch 11255VSR SDS-plus® Bulldog™ Xtreme 1 In. Rotary Hammer, a tool engineered in the tradition of the legendary Bulldog line to deliver superior performance and durability. Powered by a robust 8.0 Amp motor, this rotary hammer generates an impressive 2.0 ft-lbs of impact energy and up to 5,800 no-load BPM. Whether you are anchoring into solid concrete or breaking down masonry materials, the 11255VSR provides the raw power needed to get the job done right the first time. Weighing in at just 6.7 lbs, it offers an exceptional power-to-weight ratio, ensuring you can work longer with less fatigue.

Versatility is key for the modern professional, and this tool excels with its multi-function mode selector, allowing you to instantly switch between rotary hammer, rotation only, and hammer only modes. For precise chipping, the Vario-Lock™ positioning system lets you rotate and lock the chisel into 36 different angles, optimizing your working position. Designed for compliance and comfort, the tool works with Bosch’s PRO+GUARD™ dust solutions to help meet OSHA Silica Table 1 standards. It also features a variable-speed reversing trigger for accurate bit starting and an exclusive rotating brush plate that ensures equal power in both forward and reverse, extending the life of the brushes.
