Abstract
The invention discloses a high-strength wear-resisting drill bit. The high-strength wear-resisting drill bit comprises a body and a wear-resisting coating which coats on the surface of the body, wherein the body is prepared by integrating 92-96% (in percentage by mass) of diamonds into 4-8% of high-speed alloy steel; the wear-resisting coating is formed by polymerizing 62-78% (in percentage by mass) of polyimide and 22-38% of polytetrafluoroethylene. In this way, the high-strength wear-resisting drill bit can have excellent reliability while guaranteeing relatively high hardness, so that cracking phenomena in a using process of the drill bit are greatly reduced; and the drill bit has extremely good wear resistance and a prolonged service life.
