Makita 11lbs. SDS-Max Demolition Hammer - HM0870C
The Makita 13 lb. demolition hammer is powered by a powerful 10 Amp motor that delivers up to 8.4 ft-lb of impact energy and 1100 to 2650 BPM for chiseling, chipping and scaling operations. The ergonomically designed handle is provided with soft rubberized grip so that the user can work for long duration without any fatigue. The electronic controller offers soft start that suppresses start-up reaction for smooth start-ups and longer gear life. LED service light gives caution approximately 8 hours before brushes need to be replaced and also the LED power light indicates switch failure or cord damage. Extended life brushes are longer means more work between service intervals and minimal downtime. The 12-bit angle settings allow the bit to be set at different positions based on application requirements. Motor advantage engineered with field core interlocking steel laminations, dual ball bearing armature and more copper commutator bars, increases energy transfer efficiency for more power and longer tool life. It includes hammer bit grease and durable tool case. The easy-to-operate slide switch increases productivity and minimizes down time.
