Rotary hammer

Bosch introduces the RH228VC Bulldog Xtreme Max Rotary Hammer designed to provide maximum performance in extreme concrete drilling and chiseling applications. Able to drill holes up to 1 1/8 inch in diameter, the RH228VC can also use core bits and perform all-day chiseling. A longer piston and impact bolt, combined with a precision-machined striker, increases the hammer’s efficiency, which, in turn, increases speed and power, the maker says. www.boschtools.com/Pages/default.aspx
