R32-57mm-Q9 Threaded Button Bit

ANTI-DROPOUT & T6 ARMOR:

• Hot Insertion Mastery: By employing advanced structural hot insertion technology, the premium steel body shrinks tightly around each carbide root, virtually eliminating the operational risk of buttons dropping out mid-hole.

• T6 Global Standards: Armed with world-class T6 tungsten carbide inserts (10mm gauge + 9mm front), this 57mm model actively competes with top-tier OEM brands in structural fracture toughness and extreme abrasion resistance.

In large-bore underground drifting, blast-hole cutting, and medium-scale anchoring, tool failure usually comes down to two costly bottlenecks: rapid gauge polishing and catastrophic button dropouts. Bloom's R32-57mm-Q9 Threaded Button Bit is heavily engineered to completely eliminate these weak points on the rock face. Weighing a highly balanced 0.93kg, this heavy-duty 57mm threaded bit combines a rigid Uniface flat-head geometry with an advanced 9-button matrix (Q9), offering field-proven durability that lets mining contractors challenge global OEM performance at a smarter mid-sized enterprise price point.

The true mechanical security of this 57mm workhorse lies in its specialized metallurgy and assembly precision. We utilize premium T6-grade tungsten carbide inserts—featuring six massive 10mm gauge buttons and three 9mm front center buttons—renowned worldwide for balancing elite wear-resistance with brutal impact energy absorption. Utilizing high-precision hot insertion technology, the high-alloy steel body bonds seamlessly with the carbide stems, creating a vice-like grip that minimizes button failure inside the hole. Configured in a robust Spherical/Dome layout to maximize structural life in abrasive ground, this standard skirt bit is the ultimate economic solution for single-pass or short-hole underground tunneling applications that require infrequent uncoupling.
