New Bosch Rotary Hammers

New Bosch Rotary Hammers Offer Best Performance with Lowest Vibration Levels

RH328VC, RH328VCQ and RH432VCQ Feature Bosch Vibration Control™ Technology to Maximize Comfort on the Job

01.18.2011– LAS VEGAS, Jan. 18 – 21, 2011 – Bosch Power Tools and Accessories introduces three new, super powerful rotary hammers that maximize impact energy, minimize vibration levels, yet maintain manageable size and weight to provide the utmost comfort in extended chiseling and drilling. Bosch has incorporated its patented Active Vibration Control™ technology into the newest members of the Bulldog™ family, 1-1/8-inch SDS-Plus® RH328VC, RH328VCQ and 1-1/4-inch SDS-plus RH432VCQ Rotary Hammers. This technology reduces vibration in both the hammer mechanism and the grip area to reduce overall vibration by as much as 50 percent.

The RH432VCQ operates at 8.5 amps with 3.7-foot-pounds of impact energy, making it the fastest drilling SDS-plus hammer in its class.

The RH328VC and RH328VCQ pack 8.0 Amps of power and 2.6-foot-pounds of impact energy. Both deliver unmatched power-to-weight ratio in the rotary hammer category, with the RH328VC weighing in at a lean 7.7-pounds and only 12.5-inches in length and the RH432VCQ weighing in at only 10.3-pounds.

The compact L-shaped design improves the user’s line of sight for precision drilling, making the Bulldog family of rotary hammers ideal for electricians, plumbers, general installers, commercial and construction contractors and HVAC professionals.

Bosch’s Vibration Control™ Technology makes the hammers extremely comfortable to use. The technology features a longer air cushion built into the hammer mechanism, which combined with dampening elements in the grip area substantially reducing vibration levels at the source and provides the lowest vibration levels in this hammer class.

The new models offer three modes of operation: rotary hammer, hammer-only and rotation-only. Vario-Lock™ positioning rotates and locks the chisel into any of 12 different positions allowing users maximum control. The RH328VCQ and RH432VCQ models also include a Quick-Change chuck system for convenient change out between SDS-plus® and an optional 3-jaw chuck for use with a wide range of accessories.

A variable speed three-finger trigger ensures accurate bit starting, and a forward / reverse lever provides equal power in each direction, for ease of jam-bit removal. A 360-degree auxiliary handle and integral clutch minimize torque reaction for further control and versatility. The RH328VC, RH328VCQ and RH432VCQ come equipped with an auxiliary handle and carrying case and are available now through authorized retailers nationwide.
