R32-42mm-Q7 Threaded Button Bit

FLEET COMPATIBILITY & COMPACT PROFILE:

• OEM Replacement Perfected: This R32 42mm bit is specifically balanced for light-duty top hammer drifters. It serves as a direct, high-performance replacement when operating legendary underground rigs like the Atlas Copco Boomer 282, L2D, or equivalent Sandvik underground tunneling jumbos.

• YK05 Premium Carbide: Utilizing industry-proven YK05 grade inserts ensures maximum wear resistance when micro-drifting or quarrying dimensional natural stone.

In light-duty underground tunneling, narrow-vein mining, and dimensional natural stone quarrying, maintaining tight drilling trajectories depends entirely on the agility and weight-to-power ratio of your top hammer tools. Weighing a highly responsive 0.6kg, Bloom's R32-42mm-Q7 Threaded Button Bit is masterfully engineered to transform high-frequency percussion into sheer advancing speed. Armed with 7 premium YK05-grade tungsten carbide inserts, this compact Q7 drill bit strikes the perfect equilibrium between aggressive penetration and continuous body structural integrity.

To withstand severe gauge abrasion without suffering hole shrinkage, this model features a rugged 5+2 button matrix layout (five 9mm or 10mm gauge buttons combined with two 8mm front center inserts). This precise geometry is available in Spherical, Ballistic, or Semi-Ballistic profiles to match your precise rock elasticity. Built to effortlessly mate with R32/R28 H28 or R32/T38 H35 drift rods, it acts as the ideal front-end tool for high-production drifting jumbos including the Atlas Copco Boomer 282, L2D, and equivalent Sandvik drilling fleets. Whether handling single-pass production or short-hole bolting that requires infrequent uncoupling, this bit preserves hole cleanliness while protecting your drifter's striking bars from excessive recoil.
