T38-64mm-Q13 Heavy-Duty Drop Center Retract Button Bit

As a premier rock drilling tools factory, Bloom manufactures a comprehensive range of T38 Threaded Button Bits, the industry's most critical size for production benching and underground long-hole drilling. To ensure our tools confidently compete with global tier-one OEM brands, we exclusively select world-class T6 tungsten carbide inserts, renowned for their superior balance of wear-resistance and impact toughness.

Our manufacturing integration utilizes premium high-tensile steel tailored for advanced hot-insertion technology. This ensures the bit body holds the carbide buttons with a powerful interference fit, drastically reducing the risk of premature button drop-outs. For high-abrasion environments where structural longevity is preferred over speed, our spherical/dome carbide shapes offer the optimal cost-per-meter efficiency, while ballistic options are available for maximum penetration rates.

Explore our full T38 matrix below - available in diameters from 64mm, 76mm, to 89mm, featuring multiple skirt configurations (Normal, Retrac), face types (Flat Face, Uniface, Drop Center), and button profiles designed to match heavy-duty top hammer drifters and extension MF/MM rod systems perfectly.
