Milwaukee Electric Tool. 6527 The patented counter balance mechanism makes the Super Sawzall® Reciprocating Saw the smoothest operating, most vibration free saw in the world. This high performance Super Sawzall, at 10 amps, incorporates the patented gear protection system which absorbs high impact forces caused by sudden blade lock-up thereby extending the life of the tool even under the most extreme cutting conditions. Trigger speed control from 0-3200 SPM allows the operator to match the speed of the tool to the application. The new heavy duty steel Quik-Lok™ blade clamp system enables the user to change blades fast and easy without the use of a hex wrench.
