Insert drill bits are primarily used for drilling holes in specific applications and materials. Four common indexable drill bits:
General drill bits: General drill bits are mainly used in the automotive industry, especially in the production of critical components such as engines, suspensions and brake systems. These drill bits are usually made of high-speed steel (HSS) or solid carbide with high hardness and wear resistance to cope with the drilling requirements of metallic materials such as steel and aluminum. Due to the strict accuracy and tolerance requirements of the automotive industry, these drills require precise dimensions and geometries when designed and manufactured.
Top Drill Bit: Top drill bit is a special type of insert drill bit mainly used for deep hole drilling and high precision applications. They usually have a long cutting section and a guide tip to ensure a high degree of linear accuracy during drilling. Top drill bits are mainly used in industries such as aviation, energy and oil and gas, and usually choose high-quality steel or carbide as the base material.
Short drill bits: Short drill bits have a shorter cutting portion and are primarily used for shallow hole drilling or applications where the hole diameter is smaller. Due to their short cutting sections, they can work in confined spaces and are highly rigid, resulting in reduced vibration and improved accuracy. Short drill bits are generally suitable for drilling thin metal sheets and plastic materials, and are commonly used in the manufacturing process of electronic and household appliance products.
Long drill bits: Long drill bits have a longer cutting section and are suitable for applications that require deeper drilling or longer penetration distances. Due to their length, long drill bits may produce more vibration during drilling, so certain measures need to be taken when using them to maintain accuracy and stability. These drill bits are commonly used in construction, furniture manufacturing, shipbuilding and other industries, and are mainly used for deep hole drilling in wood, plastics, metals and composite materials.
