Available in various thread types including R25, R28, R32, SR35, R38, T45, T51, ST58, GT60, and ST68. The drill bit head diameters range from 32mm to 152mm, with button options in spherical, ballistic, and conical shapes.

Ideal for tunnel construction and large-scale mining operations, including open-pit and underground copper, gold, and other mineral extraction.

Product Features

Raised center design ensures center buttons contact rock first, improving collaring and hole straightness
Optimized flushing hole configuration (3-4 holes depending on diameter) with equally spaced grooves for balanced air flow and reduced gauge button wear
Slot-free face design promotes even air distribution, better cuttings clearance, and optimal button placement
Precisely positioned buttons provide complete cutting coverage with just 90° rotation, eliminating rock re-breaking and missed areas
Even load distribution across all buttons minimizes breakage risk and extends service life
