Catalog (SKU) Number: MK-XAG03MB

BL™ Brushless motor delivers 8,500 RPM. Automatic Speed Change™ technology adjusts speed and torque during operation for optimum performance. The BL™ Brushless Motor eliminates carbon brushes, enabling the BL™ Motor to run cooler and more efficiently for longer life. Efficient BL™ Brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge. The electronically-controlled BL™ Brushless Motor efficiently uses energy to match torque and RPM to the changing demands of the application. Compact and ergonomic design at only 14-1/4" long. Weighs only 5.5 lbs. with battery for reduced operator fatigue. Rubberized soft grip provides increased comfort on the job. 3-stage L.E.D. gauge indicates battery charge level. Slide switch with lock-on for operator convenience. Soft start suppresses start-up reaction for smooth start-ups and longer gear life. Spiral bevel gears for smoother rotations and a more efficient transfer of energy. Anti-restart protection engineered to prevent motor start up when battery is inserted with switch locked on. Efficient internal cooling is engineered for optimum performance. Wire mesh intake covers are engineered to prevent debris from entering motor.
