Makita's Reciprocating Saw (model JR3051T) delivers superior power and performance with less vibration. The JR3051T is powered by a 12 AMP motor with electronic speed control to maintain constant speed under load. The JR3051T has a long 1-3/16" stroke for faster cutting with 0-3,000 strokes per minute (SPM) and a variable speed trigger to match the speed of the saw to the application. The JR3051T has a durable body design that keeps dust and debris away from the motor, with rubber and felt seals to keep dust and water out for a longer tool life. The JR3051T weighs 7.3 lbs., with tool-less blade change.
