Product Overview

Our 9-tooth, 45mm diameter R28 threaded button drill bit is engineered for high-intensity drilling in hard rock formations including granite, gneiss, and mineral-bearing rocks. Combining a robust R28 threaded connection with optimized tooth layout and durable construction, this bit delivers superior drilling speed, hole accuracy, and extended service life for large-scale mining, quarrying, blasting, and deep foundation drilling applications.

Key Features & Benefits

Optimized 9-Tooth Design: Features nine tungsten carbide teeth arranged in an alternating pattern that prevents overlapping during drilling and ensures even impact force distribution. This design reduces friction-generated heat and increases drilling speed by 20-25% compared to 6- or 7-tooth bits of the same diameter, maintaining efficiency in extremely abrasive and hard rock formations.
R28 Threaded Interface: Industry-standard R28 threaded connection provides secure attachment to R28 drill rods and connectors, effectively preventing thread slippage or breakage during high-torque drilling operations.
Balanced 95mm Length: The short to medium-length drill body design strikes the perfect balance between rigidity and drilling depth, minimizing vibration during high-speed rotation to improve operational efficiency.
Heavy-Duty Construction: Durable design suitable for harsh working conditions with wear-resistant tungsten carbide buttons (YG10C material with density ≥14.8 g/cm³, hardness HRA ≥89) that prevent chipping under repeated high impact loads. The alloy steel body undergoes quenching and tempering heat treatment for enhanced tensile strength (≥1200 MPa) and fatigue resistance.
