Makita HR4511C 110V Rotary Demolition Hammer
With a powerful 1350w motor the Makita HR4511C 110V Rotary Demolition Hammer delivers excellent performance levels (9.4Js impact level) with very low vibration levels of only 7 m/sec² when chiseling and 7.5 m/sec² when hammer drilling. The HR4511C has two very useful modes: rotary hammer and rotary only action, and is designed with constant speed control which automatically applies additional power to the motor to maintain speed under load to complete the most demanding applications. The soft start feature ensures a slow start-up giving better accuracy and enhanced control while, when in use, the torque limiter offers additional operator protection and reduces gear damage by automatically stopping the drill if the bit hits reinforcements.
The variable speed trigger provides control making it safer and easier to work with over extended periods of time. With a no load speed of 130 – 280rpm this SDS rotary demolition hammer has a maximum application of 40mm in concrete and a maximum core diameter (TCT) of 125mm. Standard equipment includes bit grease, depth rod and side handle.
