R32-48mm-Q9 Threaded Button Bit

THE PENETRATION VELOCITY SPECIALIST:

• Aggressive Ballistic Cutting: Configured with 9 premium ballistic and semi-ballistic inserts, this 48mm model offers razor-sharp chipping mechanics, slicing through medium-to-hard stone strata at maximum velocity.

• Optimized Volumetric Flush: At a perfectly balanced 0.9kg with a flat Uniface design, it opens up the critical borehole perimeter for cleaner, faster chip evacuation without overloading your drifter's feed force.

In medium-scale underground tunneling and drifting operations, moving past standard 45mm dimensions to secure clean, high-volume blasting charges requires tooling that prioritizes cutting aggression without sacrificing gauge holding power. Bloom's R32-48mm-Q9 Threaded Button Bit is masterfully engineered to serve as your fleet's high-speed advancement leader. Weighing an optimized 0.9kg, this 48mm top hammer bit utilizes an aggressive 9-button layout (Q9) specifically paired with premium Ballistic or Semi-Ballistic tungsten carbide profiles to achieve maximum penetration rates (ROP) in non-homogeneous or uniform medium rock strata.

The structural design of this 48mm variant relies on a clean, balanced Uniface flat-head geometry that forces the high-frequency percussion waves from your rock drill directly into the rock face, avoiding energy dissipation. By selecting high-penetration ballistic buttons over standard domes, this model shears stone with minimal feed resistance, keeping hole tracking perfectly straight during deep rounds. Built to integrate effortlessly into standard underground production strings, it forms a high-rigidity pairing with R32-R28 H28 (2600mm/3100mm) and R32-T38 H35 (3660mm) Hexagonal drift rods, ensuring reliable energy transfer and minimal threat of binding or thread seizing during high-production drilling cycles.
