R32-64mm-Q12-RC Threaded Button Bit

THE HARD-ROCK HEAVYWEIGHT:

• 12-Button High Density (Q12): Armed with an ultra-dense matrix of twelve 10mm T6-grade semi-ballistic inserts, this 2.22kg powerhouse ensures zero-blind-spot crushing, maximizing penetration rates (ROP) while slashing rig fuel consumption.

• Retrac Fluid Dynamic: The heavy back-riffled retrac body, paired with dual localized front flushing ports, instantly evacuates dense rock cuttings from the 64mm perimeter, ensuring straight hole trajectories and eliminating jammed iron.

Opening up large 64mm blast holes or specialized anchoring bores with an R32 thread system typically pushes conventional tooling to its structural breaking point, resulting in severe hole deviation or premature body wash. Bloom's R32-64mm-Q12-RC Threaded Button Bit is explicitly engineered as a heavy-duty solution to conquer these high-stress underground applications. Weighing a massive, rigid 2.22kg, this premium top hammer bit introduces a high-density 12-button array (Q12) that leaves zero blind spots on the rock face, delivering elite straightness and maximum drilling performance in the toughest hard stone formations.

To combat extreme rock abrasiveness, we arm this 64mm model with world-class T6 tungsten carbide inserts, combining eight 10mm gauge buttons and four 10mm front center buttons in an aggressive Semi-Ballistic profile for rapid chipping. Utilizing high-precision hot insertion technology, the premium steel body shrinks tightly around each carbide root to eradicate mid-hole dropouts. Driven by dual front water holes and a deep-grooved, back-riffled Retrac body design, this bit sweeps dense rock fragments backward instantly, minimizing secondary grinding to lower fuel costs per meter and guarantee smooth, trouble-free drill string extraction from fractured ground.
