For contractors and tradesmen that repetitively drill into concrete, the 5363-21 delivers unmatched performance and ergonomics. The unique anti-vibration system (avs) significantly reduces vibration. The compact l-shape design makes it well balanced, easy to control and ideal for overhead drilling and anywhere that requires access to tight spaces. Delivering 2.0-Feet-Pound of impact energy and up to 5,980 blows per minute, the 5363-21 provides fast drilling and powerful chipping for increased jobsite productivity. This compact rotary hammer also features a high power, 7.0-Amp motor and a rotating brush plate which provides equal power in forward and reverse for easy removal of jammed bits and extended brush life. The all metal, magnesium gear case and block construction provide precise bearing and gear seating for long-term durability. With three modes of operation (hammer-drill, drill only, and chipping) this hammer provides maximum versatility in a compact-package.
