The Bosch 11255VSR SDS-plus Rotary Hammer comes billed as the fastest, longest lasting breed of rotary hammer. The totally redesigned BULLDOG Xtreme outlasts the competition in both speed and performance. A side-mounted multi-function selector allows 3 modes of operation: rotary hammer, hammer-only, and rotation-only mode. Vario-Lock Positioning rotates and locks the chisel into 36 different positions to optimize your working angle.
The patented rotating brush plate provides equal power in both forward and reverse, so you get as much torque and speed coming out as you do going in. There are also some nice minor touches, like how the cord turret has a 35-degree pivot for added flexibility and longer cord life.
Bosch 11255VSR SDS-Plus Rotary Hammer Features
The 11255VSR looks like a serious Bosch tool. It has a comfortable D-handle grip design for greater control, especially when drilling overhead or downward and an adjustable side or bottom-mounted handle can be pivoted around as needed to give you exactly the right grip in any situation.
All of the areas where your hands are most likely to make contact with the tool have rubber overmold, common with all of Bosch tools—and the placement of the molding is adequate and thoughtful. It also means you can use this tool with or without gloves, even if your hands get greasy or sweaty – you won’t lose your grip. The trigger easily supports a one or two-finger pull and the side-mounted Multi-function Selector means that you can quickly jump between rotation only, rotary hammer, and hammer-only modes. This is an extremely versatile tool.
The Bosch 1″ SDS-plus Bulldog uses, of course, the SDS-plus bit system which provides tool-free bit changes and automatic bit locking, dust protection, and maximum impact energy transfer rate. There is a variable-speed reversing trigger for accurate bit starting as well as for removing fasteners or bound bits. An integral clutch helps minimize torque reaction so you can use the tool more safely.
