What Characteristics Does Hammer Drill Have？

What are the characteristics of a good hammer drill? We sort out five characteristics hammer drill should have, as follows:
1. Damping system, it can not only make staff comfortable to hold, but also relieve fatigue. By "vibration control system" to achieve; soft handle increases comfort feeling to hold.
2. Speed switch, when touch the switch, speed is relatively low, the machine can help smooth tripping.
3. Stable and reliable safety clutch, during use, this is a way to avoid a large torque reaction force to the user due to catching drill arising, which is a safe protection for user.
4. Comprehensive motor protection devices, in use, it is inevitable to enter the machine for granular hard objects, if the motor does some protection, high-speed rotation can easily be touched off by a hard object or scraping wire, resulting in motor failure.
5. Reversing function, application scope of hammer drill is broader and broader, its manifestations mainly is achieved through switch or adjust the position brush. This benefit is easy to operate and effective to protect the commutator, it can also extend motor life.
