What are the specifications of electric hammer drill

Electric hammer drill bit has many models, we use something different in drill bit is also different, different material models of the bit, of course, not the same, if worry about buy the wrong that you should learn to electric hammer drill specifications carefully, only in this way can we know whether you need the drill bit, to go over the electric hammer drill specifications is what?

Electric hammer bit specifications :6mm, 8mmx110mm; 8 mmx160mm; 8mm, 10mm, 12mmx210mm, 10mm, 12mm, 16mm, 20mmx450mm.

The main body of cemented carbide electric hammer drill is made of high quality alloy steel, and the cutting head is welded with cemented carbide. It is suitable for drilling concrete, brick and other hard building materials. It is widely used and efficient drilling tool in construction and installation industry.

Electric hammer drill set specifications: 5*110mm, 6*110mm, 6*160mm, 8*160mm, 10*160mm

Electric hammer drill: round shank or square shank: 6mm 8mm 10mm 12mm 14mm 16mm-28mm 

Wall drill: length: 350mm 16mm 18mm 20mm 22mm 25mm 28mm

Electric hammer bit characteristics

1. Good shock absorption system: it can make the operator comfortable to hold and relieve fatigue.

Realization approach: through "vibration control system" to achieve; Through soft adhesive handle to increase grip comfort;

2, precise speed switch: low speed when lightly touching the switch, can help the machine smooth drilling (such as in tile and other smooth surface drilling, not only can prevent the bit slip, but also can prevent the drilling rupture. High speed can be used when working normally to ensure working efficiency.

3, stable and reliable safety clutch: also known as torque limiting clutch, avoid in the process of use due to the bit stuck and the large torque reaction force transmitted to the user, which is a kind of safety protection for the user. This feature also prevents the gear and motor from stopping.

4, comprehensive motor protection device: in use there will inevitably be granular hard things into the machine (especially for the machine up drilling, such as the top of the wall drilling), if the motor does not have a certain protection, in high speed rotation is easy to be hard things broken or scratched enameled wire, ultimately leading to motor failure.

5, positive &negative function: can make electric hammer more widespread use, its realization form mainly through switch or adjust the position of carbon brush, big tools are often used to adjust position of carbon brush brush (rotation), the advantage is easy to operate, effectively restrain spark to protect commutator, prolong the service life of the motor.

What are the precautions for the use of electric hammer drill

When we use electric hammer drill can be more careful, do not hurt yourself, must know what you should do should not do what, so it is necessary for us to understand the use of electric hammer drill precautions are? Only in this way can we pay attention to these problems when we use them, but people are not aware of it. Therefore, xiaobian hereby introduces the precautions for the use of electric hammer drill bits. What are the precautions for the use of electric hammer drill bits?

1. Confirm whether the power supply connected to the site is consistent with the nameplate of the hammer. Whether there is leakage protection device. Drill bit and gripper should fit and be properly installed.

2. When using electric hammer drill to chisel walls, ceilings and floors, it should be confirmed that there are no buried cables or pipes and so on when working at high places. Full attention should be paid to the safety of objects and pedestrians below, and warning signs should be set when necessary.

3. Confirm whether the switch on the hammer is cut off. If the power switch is switched on, the power tool will rotate immediately when the plug is inserted into the power socket, which may cause the risk of personal injury. If you need to extend cables in a place far from the power supply, install qualified extension cables with sufficient capacity. If the cable extends through the pedestrian corridor, it should be elevated or take measures to prevent the cable from being crushed and damaged
