Electric hammers are a type of electric drill used to drill holes in concrete, slabs, brick walls and stone. This article mainly introduces some characteristics of electric hammer.
1. Good shock absorption system: It can make the operator feel comfortable and relieve fatigue.
The way to achieve: through the "vibration control system" to achieve; through the soft rubber handle to increase the grip comfort ;
2, accurate speed switch: low speed when tapping the switch, can help the machine to start drilling smoothly (for example, drilling on a smooth surface such as ceramic tiles, not only can prevent the drill bit from slipping, but also prevent the drill hole from rupturing. Normal work High speed can be used to ensure work efficiency.
3. Stable and reliable safety clutch: Also known as torque limiting clutch, it avoids the large torque reaction force generated by the bit stuck in the user during use, which is a kind of safety protection for the user. This feature also prevents the gear unit and the motor from stopping.
4, comprehensive motor protection device: in use, there will inevitably be granular hard objects entering the machine (especially drilling the machine upwards, such as drilling the top of the wall), if the motor does not have certain protection, rotate at high speed The middle pole is easily broken or scratched by the hard object, which eventually leads to motor failure.
5, positive and negative function: can make the hammer more widely used, its implementation is mainly achieved by switching or adjusting the position of the carbon brush. Usually the big-name tools will be adjusted by adjusting the position of the carbon brush (rotary brush holder). The advantage is that it is easy to operate, effectively suppress sparks to protect the commutator and extend the service life of the motor.
