The Makita HM1307CB 35 lb. Demolition Hammer combines hard-hitting power with additional features including soft start and a variable speed control dial for improved performance. The HM1307CB accepts 1-1/8” Hex Bits, and is ideal for both horizontal and vertical demolition and breaking applications. 14 AMP Power The HM1307CB is engineered with a 14 AMP motor that provides 730-1,450 BPM and 34.9 joules (25.7 ft.lbs.) of impact energy, with constant speed control that automatically applies additional power to the motor to maintain speed under load. Consistent with the rest of Makita’s concrete hammer line-up, the HM1307CB is engineered with the Makita Motor Advantage. This includes field core interlocking steel laminations, dual ball bearing armature, and large surface commutator. These features deliver the most efficient transfer of energy for more power and longer tool life. Additional performance features include soft start, which suppresses start-up reaction for more control and greater accuracy. The L.E.D. service/power indicator indicates switch failure or cord damage, and also notifies the user approximately 8 hours before the brushes need to be replaced. At the same time, the HM1307CB is engineered with extended life brushes which are longer for more work between service intervals and less downtime. The HM1307CB has a large side handle with an easy-to-operate switch control. For added convenience, the HM1307CB has a 16.4 ft. cord and accepts 1-1/8” Hex Bits for a wide variety of demolition applications. Engineered for a Range of Applications The HM1307CB is a hard-hitting demolition hammer and is engineered for a range of applications including breaking up concrete and heavy structural demolition, landscape and trench work, trench and footing compaction with tamper plate, asphalt removal, driving ground rod and tent stakes, and more.
