cutting structure
The tooth surface of the pot scratching drill bit is coated with a new wear-resistant alloy to enhance the wear resistance of the cutting teeth. The tooth drill bit adopts high-quality carbide teeth with new formula and new technology to improve the comprehensive mechanical performance of the cutting teeth.
Gauge structure
It adopts a multiple gauge structure, with trimming teeth (GT teeth) on the outside of the teeth, alloy teeth on the wheels and claw backs, and wear-resistant alloy surfacing on the claw tips and front sides to improve the drill's warp retention capability. Bearing structure
It adopts high-precision matching radial sliding and axial thrust bearings and steel ball locking. The claw shaft is pre-welded with a resistant alloy, and the inner hole of the gear is welded with a special alloy and hammered, which moistens the corrosion resistance and anti-seize ability of the bearing pair, and improves the bearing's ability to adapt to high speeds.
Seal lubrication
Adopting an advanced metal seal, the metal seal structure is composed of two metal rings and two elastic rubber seals. The elastic force generated after the seal is compressed causes the sealing surfaces of the two metal rings to converge, thus Achieve bearing sealing. During the drilling process, the metal sealing surfaces move relative to each other, while the energy supply is stationary relative to the claw journal and the gear seal groove respectively, significantly improving the reliability and life of the bearing seal. The reportable pressure difference oil storage compensation system improves the reportability of bearing lubrication. Use special lubrication for performance drill bits. Product use
The metal seal drill bit has high sealing reliability and is suitable for parallel drilling of power drilling tools and high drilling speed rotary table drilling.
