Makita® Corded Rotary Hammer Drill, 1-9/16 in Chuck, Spline Chuck, 1300 to 2600 BPM, 6.8 ft-lb Impact, 230 to 460 RPM No-Load Speed, 4-5/8 in Max Core Bit Compatibility, 1-9/16 in Maximum Solid Bit Capacity, 120 VAC, 12 A, Forward Switch Control, 16-7/8 in OAL. The Makita® HR40410C Toothed Shaft 1-9 / 16 in Rotary Hammer Features a Powerful 12 A Engine Designed with a Central Field of Interlocking Steel Blades, Dual-Bearing Rotor and Large Switch Surface Area For Energy Efficient Transfer Produces up to 230 to 460 RPM and 1300 to 2600 BPM and Has 2 Modes of Operation For Just Hammering and Hammering with Rotation Soft Start Functionality Facilitates Control and Improves Accuracy While The Sequential Impact Counter Promotes Faster Work.
Features
- Constant speed control that automatically applies more power to the engine to keep the speed under load and finish more challenging jobs
- Torque limiter clutch designed to reduce damage to gears by releasing gears automatically if the bit gets stuck
- Soft start feature gradually increases speed to eliminate start up shock
- Variable speed dial allows operator to adjust speed based on materials or application
- Auto shut-off carbon brushes shut-off motor when carbon brushes require replacement
- No load motor suppression limits vibration and bit deflection when idling
- Ergonomic soft rubber grip design for vibration absorption and comfortable operation
- Sequential impact counter that produces hammering measured during rotation to minimize overlap of drill impacts for drilling up to 50% faster
- Automatic brush-off system to protect the switch from damage
- Two-mode operation "hammering only" or "hammering with rotation"
- No hammering at rest function help increase tool life
- High quality aluminum housing for durability
- Engineering advantage of the Makita® engine with a central field of interlaced steel blades, rotor with dual bearings and more copper switch bars, increasing energy transfer efficiency for more power and longer life
- 16.4 ft cable length
- 9.2 J impact power
- 15 m/sq-s vibration
- 1/2 to 1 in optimal range (concrete drilling)
- Powerful 12 A motor produces 6.8 ft-lb power to handle the most demanding applications
