ⅠClassification of Electric Drill Bits
Electric drill bits can be divided into many types according to the use and shape, of which the more common are the following:
1. Woodworking drill bits: can be used for drilling wood products, plastics and other materials.
2. Metal drill bits: suitable for drilling copper, aluminum, stainless steel, steel and other metal materials.
3. Tile drill bit: mainly used for drilling tiles, glass and other hard and brittle materials.
4. Concrete Drill Bit: Specially used for drilling concrete, stone and other hard materials.
5.Center Drill Bit: Used for centering the working material for subsequent processing.
Ⅱ Drill Bit Material
The material of the drill bit has a great influence on its performance and life. The common drill materials are as follows:
1. High-speed steel (HSS): suitable for drilling steel, aluminum and other materials, with good wear resistance of the bit.
2. Tungsten steel (WC): mainly used for drilling hard materials, such as diamonds, tiles and so on.
3. Tungsten Carbide (WC): It is suitable for drilling hard materials such as concrete, stone and so on.
Ⅲ Drill Specifications
The specifications of drill bits are generally labeled according to the diameter, such as 3mm, 6mm, etc.. In general, the smaller the diameter of the drill bit, the higher the processing requirements, while the larger the diameter of the drill bit, it is suitable for processing rough materials.
Ⅳ Purchase of Electric Drill Bits Considerations
1. Select the drill according to the required processing materials, do not choose blindly.
2. Select the diameter of the drill according to the degree of fineness required, and do not pursue a large diameter too much.
3. When purchasing drill bits, you can choose some products with brand guarantee to ensure the quality and life.
4. When using drill bits, pay attention to the use of appropriate processing fluid for cooling and lubrication, in order to extend the service life of drill bits.
5. Check the wear of the drill bit in time, and replace the damaged drill bit in time to avoid affecting the machining efficiency.
