There are many models of electric hammer drill, we drill different things when the use of the drill is not the same, of course, different materials of the drill model is not the same, if you are worried about buying the wrong it is necessary to carefully learn the electric hammer drill specifications model, only in this way we can know whether they need the drill bit, together to see what is the electric hammer drill specifications model?

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

Carbide electric hammer drill body is made of high quality alloy steel, and the cutter head is welded by carbide. With a variety of electric hammer machine supporting use, suitable for concrete, brick and other hard building materials drilling. It is a widely used and efficient punching tool in the construction and installation industry.

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

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

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

Electric hammer drill features

1, good shock absorption system: can make the operator comfortable to hold, relieve fatigue.

Realization way: through the "vibration control system" to achieve; Soft rubber handle to increase the comfort of holding;

2, accurate speed control switch: The speed is low when the switch is touched, which can help the machine to drill smoothly (such as drilling on smooth surfaces such as tiles), not only to prevent the drill bit from slipping, but also to prevent the drilling hole from breaking. High speed can be used during normal operation to ensure work efficiency.

3, stable and reliable safety clutch: also known as torque limiting clutch, to avoid the large torque reaction force caused by the stuck bit during use to be transmitted to the user, which is a safety protection for the user. This feature also prevents the gear unit and the motor from stopping.

4, comprehensive motor protection device: in use, it is inevitable that there will be granular hard objects into the machine (especially for the machine drilling upward, such as drilling on the top of the wall), if the motor does not have a certain protection, it is easy to be broken or scratched by hard objects in high-speed rotation, and eventually lead to motor failure.

5, positive and negative rotation function: can make the hammer more widely used, its realization form is mainly achieved by switching or adjusting the position of the carbon brush, usually big tools will be used to adjust the position of the carbon brush (rotating brush holder) to achieve, the advantage of this is easy to operate, effectively inhibit the spark to protect the commutator, extend the service life of the motor.

What are the precautions for the use of electric hammer drill

We can be more careful when using the electric hammer drill, do not hurt yourself, must know what you should do what not to do, so we need to understand the use of electric hammer drill precautions are what? Only in this way will we notice these problems when using, but people are not aware of here, so Xiaobian hereby introduces the precautions for the use of electric hammer drill, what are the precautions for the use of electric hammer drill are introduced as follows:

1. Confirm whether the power supply connected to the site is consistent with the nameplate of the electric hammer. Whether the leakage protector is connected. The drill and the gripper should be fitted and properly installed.

2, the use of electric hammer drilling walls, ceilings, floors, should first confirm whether there are buried cables or pipelines in the height of the operation, to pay full attention to the following objects and pedestrian safety, if necessary, set warning signs.

3. Confirm whether the switch on the electric hammer is cut off. If the power switch is on, the electric tool will turn unexpectedly when the plug is inserted into the power socket, which may lead to the risk of personal injury. If cables need to be extended in a place far from the power supply, use qualified cables with sufficient capacity. If the extension cable passes through the pedestrian walkway, it should be elevated or take measures to prevent the cable from being damaged by rolling.
