  • 【Specifically designed for left-hand threads and anti-loosening】 Distinctive left-hand (anti-clockwise) cutting, engineered for centring before left-hand thread tapping, effectively preventing workpiece loosening when machining viscous materials.
  • 【Type B Structure, Dual-Effect in One Step】 Integrated Type B design incorporating a protective cone simultaneously drills a precise 60° centring hole and a 120° end-face protective hole in a single pass, delivering high machining efficiency.
  • 【Enhanced Tapping and Centring Quality】 Left-hand centring creates a smooth force environment for subsequent left-hand tapping, while downward cutting pressure stabilises the workpiece, improving hole positioning quality.
  • 【High-quality High-speed Steel】 This drill bit is constructed from high-quality high-speed steel and undergoes strict heat treatment processes. It possesses excellent hardness and wear tolerance, enabling extended service longevity.
