Bosch debuts hardest hitting hammer with optimal vibration control
Bosch Power Tools brings vibration control technology to new heights and achieves best-in-class performance with the brand new Bosch RH850VC 1-7/8-inch SDS-max Rotary Hammer. The hardest hitting and fastest drilling hammer in its class according to European Power Tool Association guidelines, the RH850VC boasts several features that maximize productivity and minimize wear and tear on the user.
Delivering a total of 9.3 foot-pounds of impact energy, the RH850VC has up to 35% more impact energy than key competitors. In addition, optimized RPMs ranging from 150-305, BPM's from 1,380-2,760 and a 13.5 amp motor, enable the RH850VC to enhance productivity during all-day use and allow users to get more done in less time on the jobsite. With a drilling speed up to 44 percent faster than competitors (1-1/4" diameter bits) and a chiseling removal rate up to 40 percent faster, the RH850VC is both the hardest hitting and fastest drilling hammer in its class.
The RH850VC is the first Bosch Hammer to feature three levels of vibration control. The first level is a longer air cushion, the second level consists of a tuned mass damper and the final, third level of vibration control the tool's decoupled main handle. Together, this combination of vibration control technologies provide up to 60 percent less vibration than the tool's previous model and between 15 percent – 60 percent less than leading competitors. The extended air cushion design between the piston and striker in the hammer mechanism reduces vibration levels and improves impact energy and performance while a spring-loaded counter weight (tuned mass damper) moves in counter motion to the hammer mechanism, further reducing vibration levels at the source. A de-coupled main handle design rounds out the vibration control, absorbing vibrations before they reach users' hands.
The tool's SDS-max bit system offers users tool-free bit changes, an automatic bit lock once the accessory has been inserted, built in dust protection and the maximum impact energy transfer rate. A Vario-lock mechanism rotates and locks the hammer's chisel into 12 different positions to optimize a variety of working angle while a selector knob gives users the option to select from several functions including hammer drilling, chiseling only or the Vario-lock function. A variable speed dial allows for controlled drilling and demolition applications while Constant Response circuitry provides soft-start and overload protection and maintains constant speed under load. The new hammer also includes service minder brushes that indicate when preventative maintenance is required.
