I. Definition of the Bit
The bit, as an important component of a screwdriver, serves to cooperate with the screwdriver for the installation and removal of screws. Different types of bits are suitable for different specifications and types of screws, so choosing the appropriate bit is crucial.
1. Bit, as a screwdriver head, is often installed on a drill or hammer to tighten or loosen screws. It is also known as an electric screwdriver, a small electric tool widely used in various screw operations.
2. There are many types of bits, and their models are mainly distinguished by the head shape, including flat, cross, diamond, star, square, hexagonal, and Y-shaped, etc. Among them, flat and cross screw bits are the most common, while hexagonal screw bits are often used for hexagonal hole screws in industrial machines.
II. How to Choose the Appropriate Electric Screw Bit Specification?
Electric screw bits, as wear-and-tear accessories that frequently come into contact with screws during use, need to be replaced regularly. However, when choosing a new bit, we often face a problem: how to determine the required specification? Next, we will explore several methods for confirming the specification of the electric bit.
1. Determine the required bit type
When choosing an electric screw bit, the first task is to determine the required bit type. Common bit types include flat, cross, diamond, star, square, hexagonal, and Y-shaped. During the selection process, one should first refer to the specifications of the electric screwdriver to ensure that the selected bit matches the tool.
2. Precisely measure the size and shape of the bit socket on the electric screwdriver
To ensure that the bit shape fits the electric screwdriver perfectly and the size is accurate, neither too large nor too small should be chosen to ensure that the bit can be smoothly inserted and used.
3. Precisely select the diameter of the screws to be installed or removed
The size of the electric screw bit needs to strictly match the diameter of the screws to be installed or removed. For example, if you need to remove or install M4 screws (with a threaded part diameter of 4 millimeters), you should choose a bit with the same diameter of 4 millimeters.
4. Precisely match the size of the cross pattern on the screw cap
The size of the cross pattern on the screw cap is crucial for the selection of the bit. If the cross pattern is fine, a sharper bit should be selected; if there are two different sizes of patterns, the one with the finer size should be chosen first.
III. Installation and Disassembly Methods of Electric Screw Bits
After selecting the appropriate electric screw bit model, the next step is to understand how to remove the old bit and install the new one correctly. Next, we will introduce the installation and disassembly steps of the electric bit.
1. Detailed disassembly steps
First, push the sleeve at the end of the electric bit to the end, ensuring it is tightly against the bit. Then, gently pull out the bit along the groove direction. Finally, release the sleeve, so the old bit can be smoothly removed from the electric screw bit.
2. Detailed installation steps
First, push the sleeve at the end of the electric bit to the end, ensuring it is tightly against the bit. Then, smoothly insert the bit into the main shaft along the groove direction. Finally, release the sleeve, so the new bit can be securely installed on the electric screw bit.
Next, ensure the electric screw bit is in the closed state, then turn on the power switch. When the bit is close to the screw, gently turn the switch to easily tighten or loosen the screw. During the operation, please control the force carefully to avoid excessive force causing damage to the screw or the bit.
