Rotary drill bit

Rotary drilling teeth, also known as bullet heads, are mainly used for rotary drilling spiral drills. Widely used in pile foundation construction projects such as municipal construction, highway bridges, high-speed rail construction, and high-rise buildings.

Advantage

  • In terms of hard surface material welding, we use PTA powder metal deposition and other leading domestic surfacing welding methods to finish, and deposit a layer of wear-resistant alloy layer on the surface of the substrate. While retaining the original mechanical properties of the substrate, we greatly enhance the wear resistance and impact resistance of the product, thereby extending its service life.
  • In terms of hard alloys, we closely cooperate with top domestic and foreign hard alloy manufacturing enterprises and advanced technology enterprises to ensure the provision of high-quality alloys to us.
