Bosch Vibration Control Rotary Hammers
Bosch is introducing a new family of rotary hammers that they say has both reduced vibration and increased impact strength. The technology behind the improvement has something to do with, "an innovative new approach to the striker pin assembly."
According to the press release,
"A slightly longer air cushion between the piston and the striker pin significantly reduces vibration at the point of impact while increasing impact energy by about 10% at same time. The new design ultimately yields significantly faster drilling (+ 20%) in concrete. The second component of the system is a shock-absorbent main handle. Rubber damping elements at the top and bottom of the handle further isolate the user from vibration. The end result is greater productivity and all day comfort."
It looks like the Vibration Control technology is going to be present in the new 11264EVS and 11265EVS 1-5/8" rotary hammers and the 11321EVS 12-pound demolition hammer. No word if this technology will be transferred to the smaller hammer-drills like our favorite, the Bosch Bulldog. These tools are available now and will all cost between $550 and $600.
