Anti Vibration Technology on this reciprocating saw cuts down on vibration being transferred to the operator for greater comfort The Makita JR3070 has a powerful 15 AMP motor with electronic speed control which enables it to maintain constant speed under load. The built-in clutch reduces gear damage by disengaging the gears if the blade binds. 4-position orbital/straight cutting action. The Anti Vibration Technology coupled with a shock-absorbing handle dramatically cut down on vibration being transferred to the operator. Makita\'s Anti Vibration Technology works with an internal balancer which is moved by the air pressure created inside the drill housing. The balancer moves in the opposite direction thus acting as a perfectly timed counterbalance. Variable speed control dial enables the user to match the speed to the application. The saw has a 32mm long stroke for faster cutting, \"Tool-less\" blade change and shoe adjustment. The handle has an ergonomically designed rubberized grip for more comfort and there is a large 2-finger trigger with a lock-on button for added convenience. This lightweight tool is ideal for framers, carpenters, electricians, plumbers, demolition work and other demanding cutting applications.
