Tapered Drill Bit

A tapered drill bit is the essential rock-breaking tool designed to connect to the drill rod via a precision-machined conical interface (available in 7°, 11°, and 12° tapers). This robust design ensures a 98% efficient transfer of impact energy, enabling fast penetration in various rock formations.

Fitted with high-grade tungsten carbide buttons (spherical, parabolic, ballistic, or conical) and dual/triple flushing holes, it delivers an extended service life and rapid slag removal.

Ideal for mining, quarrying, and construction, it provides a reliable, cost-effective solution with quick bit changeover and low maintenance.
