What are the specifications and models of electric
There are many models of electric hammer drills. The drills we use when drilling different things are also different. Of course, the drill models of different materials are different. Only in this way can we know whether it is the drill we need. Let's take a look at the specifications of the electric hammer drill. Electric hammer drill specifications: 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 building materials such as concrete and bricks. 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 Electric hammer drill: round or square shank: 6mm 8mm 10mm 12mm 14mm 16mm-28mm Wall drill: length 350mm 16mm 18mm 20mm 22mm 25mm 28mm Characteristics of electric hammer bit 1. Good shock absorption system: it can make the operator comfortable to hold and relieve fatigue. Realization way: through the 'vibration control system'; through the soft rubber handle to increase the grip comfort; 2. Accurate speed control switch: when the switch is touched, the speed is low, which can help the machine to start drilling smoothly (for example, drilling on a smooth surface such as ceramic tiles, which can not only 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. Stable and reliable safety clutch: also known as torque limiting clutch, to avoid the transmission of large torque reaction force caused by the bit stuck 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. Comprehensive motor protection device: During 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 with hard objects, which will eventually lead to the failure of the motor. 5. Positive and negative rotation function: It can make the electric hammer more widely used. Its implementation form 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) to achieve this. The advantage is that it is easy to operate, effectively suppress sparks to protect the commutator, and extend the service life of the motor. What are the precautions for the use of electric hammer bits We must be more careful when using electric hammer drills, don't hurt yourself, we must know what we should do, so we need to understand what are the precautions for using electric hammer drills? Only in this way will we notice these problems when using it, but people are not aware of it, so the editor hereby introduces the precautions for the use of electric hammer bits, what are the precautions for the use of electric hammer bits The introduction is as follows: 1. Confirm whether the power supply connected to the site matches the nameplate of the electric hammer. Whether there is a leakage protector. The drill bit and the gripper should be adapted and properly installed. 2. When using electric hammers to drill walls, ceilings, and floors, you should first confirm whether there are buried cables or pipes, etc. when working in high places, pay full attention to the safety of the objects and pedestrians below, and set up warning signs when necessary. 3. Confirm whether the switch on the hammer is cut off. If the power switch is turned on, the power tool will turn unexpectedly immediately when the plug is inserted into the power socket, which may cause personal injury. If the work place is far away from the power source, when the cable needs to be extended, sufficient capacity should be used to install a qualified extension cable. The extension cable should be elevated or pass through measures to prevent the cable from being damaged by rolling.
