The difference between high-speed steel drill bits made of different materials

High carbon steel 45# is used for twist drill bits for soft wood, hard wood, and soft metal, while GCr15 bearing steel is used for soft woods to general iron. 4241# high-speed steel is suitable for soft metals, iron, and ordinary steel, 4341# high-speed steel is suitable for soft metals, steel, iron, and stainless steel, 9341# high-speed steel suitable for steel, iron, and stainless steel, 6542# (M2) high-speed steel is widely used in stainless steel, while M35 is widely used in stainless steel.

The most common and poorest steel is 45# steel, the average one is 4241# high-speed steel, and the better M2 is almost the same.

1. 4241 material: This material is suitable for drilling ordinary metals, such as iron, copper, aluminum alloy and other medium and low hardness metals, as well as wood. It is not suitable for drilling high hardness metals such as stainless steel and carbon steel. Within the scope of application, the quality is pretty good and suitable for hardware stores and wholesalers.

2. 9341 material: This material is suitable for drilling ordinary metals, such as iron, copper, aluminum alloy and other metals, as well as wood. It is suitable for drilling stainless steel sheets. It is not recommended to use thick ones. Quality is average within the scope.

3. 6542 material: This material is suitable for drilling various metals, such as stainless steel, iron, copper, aluminum alloy and other medium and low hardness metals, as well as wood. Within the scope of application, the quality is medium to high and the durability is very high.

4. M35 cobalt-containing material: This material is the best-performing grade of high-speed steel currently on the market. The cobalt content ensures the hardness and toughness of high-speed steel. Suitable for drilling various metals, such as stainless steel, iron, copper, aluminum alloy, cast iron, 45# steel and other metals, as well as various soft materials such as wood and plastic.

The quality is high-end, and the durability is greater than any of the previous materials. If you decide to use 6542 material, it is recommended that you choose M35. The price is slightly higher than 6542, but it is definitely worth it.
