Twist drill material what
Drill is a kind of rotary and the head end has the cutting ability of tools, the commonly used drill is made of carbon tool steel, special tool steel, high speed steel and other materials by milling or rolling and then after quenching, tempering heat treatment after grinding. However, in order to further improve its wear resistance, it can process holes in hard materials at high speed, and also makes use of cemented carbide materials, including welded bits and integral cemented carbide bits. At present, there are drill bits using gold steel, its hardness is harder.
1, carbon steel
Cheap, average performance;
2. High speed steel
The price is medium and the performance is good.
3. Hard alloy
The higher the price, drill some especially hard materials.
Twist drill material is what
Twist drill material has 45# high carbon steel for soft wood, hard wood, soft metal, GCr15 bearing steel for cork and general iron, 4241# high speed steel for soft metal, iron and ordinary steel, 4341# high speed steel for soft metal, steel, iron, stainless steel, 9341# high speed steel for steel, iron, stainless steel, 6542# (M2) high speed steel is widely used in stainless steel, M35(cobalt high speed steel) is widely used in stainless steel. The most common difference is 45# steel, general with respect to 4241# high-speed steel, good point M2 is about the same.
1, 4241 material: this material is suitable for drilling ordinary metal, such as iron, copper, aluminum alloy and other low hardness metal, as well as wood, is not suitable for drilling stainless steel, carbon steel and other high hardness metal. In the scope of application, the quality is still good, suitable for wholesale sales of hardware stores.
2, 9341 material: this material is suitable for drilling common metal, such as iron, copper, aluminum alloy and other metals, as well as wood, suitable for drilling stainless steel sheet, thick is not recommended. In the scope of application, medium quality.
3, 6542 material: this material is suitable for drilling all kinds of metal, such as stainless steel, iron, copper, aluminum alloy and other low hardness metal, as well as wood. In the scope of application, high quality, durability is very high.
4. M35 cobalt material: this material is the best grade of high speed steel in the market at present. Cobalt ensures the hardness and toughness of high speed steel. Suitable for drilling all kinds of metals, such as stainless steel, iron, copper, aluminum alloy, cast iron, 45# steel and other metals, as well as wood, plastic and other soft materials. The quality is high-grade, and the durability is greater than any of the previous materials. If you decide to use 6542 material, we suggest you choose M35. The price is slightly higher than 6542, but the absolute value is better.
