2.Craft & Performance
The Black Triangle Drill Bit features a high-strength integrated hard alloy tip with high hardness and strong wear resistance, which can pierce tile, brick and light concrete directly without pre-drilling. The tip of the Black Triangle Drill Bit is precisely ground to keep positioning stable, effectively avoiding hole deviation and rough edge chipping during drilling. The drill body of the Black Triangle Drill Bit is finely polished with uniform anti-rust coating, reducing friction and preventing rust after long-term storage. Two styles of U-shaped chip removal grooves are adopted on the Black Triangle Drill Bit: small sizes use single U grooves while larger sizes use double U grooves, which can discharge stone dust, wood scraps and cement residues smoothly without blockage. The round shank version of the Black Triangle Drill Bit fits standard drill chucks, while the triangular shank of the Black Triangle Drill Bit increases clamping friction to eliminate slipping under high torque drilling load. All edges of the Black Triangle Drill Bit are deburred smoothly, ensuring safe installation and stable long-hour continuous drilling operation.
