| Bosch introduces new Vibration Control technology  Bosch Power Tools and Accessories introduces new Vibration Control technology. The vibration dampening system will now be featured on Bosch's new 11264EVS and 11265EVS 1-5/8" Rotary Hammers and the 11321EVS 12-pound Demolition Hammer. While competitor systems rely on elaborate shock absorbing systems and other added parts, Bosch's Vibration Control system utilizes two simple, common sense components to achieve the same - or better - results. The system starts with an optimized impact mechanism. 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. "The heart of the Vibration Control technology we're launching now is an idea we initially utilized on our popular JACK 35-pound breaker hammer, with proven results," says Mitch Burdick, Bosch's Hammer Category product manager. "JACK proved to users it was possible to reduce vibration and increase power at the same time, and these new hammers will show users just how far we've pushed the envelope since then." The new 1-5/8" Vibration Control rotary hammers are identical except for their tool holders; the 11264EVS features an SDS-Max holder, while the 11265EVS utilizes a spline holder. While the Vibration Control features reduce vibration by as much as 20 percent, both hammers draw an impressive 8.1 ft-lbs of impact energy out a sturdy 13 amp motor to deliver the best power-to-weight ratio in its class. New for the 11264EVS specifically is Bosch's exclusive One-Hand SDS-Max holder. The one-handed, tool free system makes changing bits faster and easier than ever before. Both hammers feature Constant Response Circuitry to maintain speed under load and protect against overloads, Turbo Power to deliver 20 percent more power in hammer only mode and Vario-Lock Positioning that enables chisel tools to rotate and lock into 12 different positions. Other innovative features include Bosch's Auto-Max variable speed dial, which ensures maximum speed every time the tool is turned on. The Service Minder light maximizes tool longevity by indicating when preventive maintenance is required, and Bosch's patented cord turret design minimizes cord wear. Both hammers deliver an operating range of 170-340 RPM and 1700-2900 BPM for terrific performance in a wide variety of applications. In the case of the new 11321EVS Demolition Hammer, Bosch's Vibration Control system boasts a phenomenal 50 percent reduction in vibration along with an increase in impact energy of about 10%. In fact, the hammer's 9.6 ft-lbs of impact force delivers the fastest removal rate in the 12-pound demo hammer class, up to 40 percent faster in some cases. Like the new 1-5/8" rotary hammers, the 11321EVS demo hammer includes a wealth of performance enhancing features - Constant Response Circuitry, Vario-Lock Positioning, Auto-Max variable speed dial to control the hammer's 1300-2900 BPM operating range, Service Minder light and patented cord turret design. The 11321EVS features the addition of a sturdy ergonomically designed auxiliary handle to help users maintain the best possible working posture, regardless of application. All three of Bosch's new Vibration Control hammers come complete with sturdy carrying cases. The 11321EVS also includes a pointed SDS-Max chisel. write your comments about the article :: © 2009 Construction News :: home page |
