The commonly used materials for headwalks include high-speed steel, cemented carbide, ceramics, diamond, etc.
1. High-speed steel
High-speed steel is an alloy steel containing tungsten, molybdenum, chromium, cobalt and other elements, which is widely used in the drilling of metal materials because of its high hardness, good toughness and strong wear resistance. HSS drill bits are suitable for drilling low-strength materials, such as steel, cast iron, copper, aluminum, plastic and other materials, and the price is moderate, which is a common drill bit material.
2. Cemented carbide
Tungsten carbide, also known as tungsten carbide steel, is a cermet material made of metals such as tungsten and cobalt and non-metallic powders such as tungsten carbide sintered at high temperatures. Tungsten carbide drill bits have the characteristics of high hardness, high strength, high wear resistance, etc., and are suitable for processing hard materials, such as stainless steel, alloy steel, titanium alloy, etc. Tungsten carbide drill bits are more expensive, but they have a long life and are a high-efficiency drilling material.
3. Ceramics
Ceramic drill bits are made of ceramic materials such as alumina and silicon nitride, which have the characteristics of high hardness, high wear resistance, high temperature stability, etc., and are suitable for processing glass, ceramics, quartz and other materials. Ceramic drill bits are more expensive, but they have a long life and are suitable for high-precision machining.
Fourth, diamond
Diamond drill bits, also known as superhard drill bits, are made of diamond powder and metal powder by high temperature and high pressure. Diamond drill bits have excellent hardness and wear resistance, and are suitable for machining hard materials such as glass, ceramics, quartz, marble, granite, etc.
To sum up, the commonly used materials of drill bits include high-speed steel, cemented carbide, ceramic, diamond, etc., and drill bits of different materials are suitable for different materials and processing requirements. When selecting a drill bit, it is necessary to select the appropriate drill bit material and specifications according to the hardness, adhesion, thermal stability and other characteristics of the processed material to obtain the best processing effect.
