drillmanufacturing
Drill bit manufacturing is a complex industrial process that transforms raw materials into the precise cutting tools used for drilling holes. The primary material for drill bits is high-speed steel (HSS), renowned for its hardness and ability to withstand high temperatures. Other materials like carbide, cobalt, and even diamond are used for specialized applications requiring extreme durability or for cutting very hard substances.
The manufacturing process typically begins with selecting the appropriate material, which is then heated and shaped.
Heat treatment is a critical step, involving precise heating and cooling cycles to harden the steel and
Surface treatments, such as black oxide coating or titanium nitride (TiN) coating, are often applied to further
