The hammer drill is a hand-held power tool that combines the functions of "impact drill" and "electric hammer". The main impact drill is rotary cutting. Reciprocating hammering movement perpendicular to the rotating face of the drill bit. The electric hammer uses the movement of the piston to compress the gas to impact the drill bit. Without much effort, you can open holes in hard materials such as concrete, brick, and stone. So what are the specifications of the electric hammer bit?

Electric hammer drill specifications
Â
There are many specifications and models of electric hammer drills. The drills we use when drilling different things are also different. The specifications of different material drills are also different. If you are worried about buying the wrong one, you must carefully understand the electric hammer. Drill specifications, only in this way can we find the drill we need. Electric hammer bit specifications are generally 6mm, 8mmx110mm; 8mmx160mm; 8mm, 10mm, 12mmx210mm, 10mm, 12mm, 16mm, 20mmx450mm.
The main body of the cemented carbide hammer drill is made of high-quality alloy steel, and the cutter head is welded with cemented carbide. Used with various electric hammer machines, suitable for drilling holes in hard construction materials such as concrete and brick. It is a versatile and efficient punching tool in the construction and installation industries. The specifications of the electric hammer bit set are 5 * 110mm, 6 * 110mm, 6 * 160mm, 8 * 160mm, 10 * 160mm.

　 Hammer drill features
Â
1. A good shock absorption system can make the operator comfortable to hold and relieve fatigue. The way to achieve: through the "vibration control system"; through the soft rubber handle to increase the grip comfort.
2. Accurate speed control switch, the lower speed when you touch 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 breaking. Normal work High speed can be used to ensure work efficiency.
3. A stable and reliable safety clutch, also known as a torque limiting clutch, avoids the transmission of large torque reaction force generated by the bit jamming during use to the user, which is a safety protection for the user. This feature also prevents the gear unit and motor from stopping.
4. A comprehensive motor protection device, during the use, it is inevitable that granular hard objects will enter 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 It is easy to break or scratch the enameled wire by hard objects, which eventually leads to the failure of the motor.
5. The positive and negative reversal function can make the electric hammer drill more widely used. Its implementation is mainly achieved by switching or adjusting the position of the carbon brush. Usually, big-name tools will use the adjustment of the position of the carbon brush (rotating brush holder). The advantage of this is easy operation, effective suppression of sparks to protect the commutator, and extend the life of the motor.
6. The double function of the hammer drill has both the impact force of the electric hammer and the penetrating power of the electric drill.
The above is the relevant introduction about the specifications of the electric hammer drill bit and the characteristics of the electric hammer drill. The electric hammer is actually a very common type of electric drill in our daily life, but the electric hammer uses the piston movement to make holes in the wall. Learn more about the relevant knowledge content in this area will make everyone more effective in actual operation.
