T38 Integral Reaming Button Bit with T.C. Tipped Pilot (64mm - 102mm)

Eliminate tool decoupling risks and slash your underground drifting cycle times. As an advanced rock drilling tools manufacturer, Bloom delivers the T38 Integral Reaming Button Bit, consolidating the pilot guide and the enlarging reamer portion into a single, high-rigidity steel masterpiece. To ensure our tools perform on par with internationally well-known brands, we apply a precise hot (thermal)-insertion processing procedure to secure our tungsten carbide buttons with massive interference fit, completely eliminating premature button drop-outs.

Each integral reamer features a T.C. (Tungsten Carbide) Tipped head on its pilot adapter portion to maintain exceptional guiding straightness while the specialized flute profiles evacuate aggressive drilling mud seamlessly. Available in standard high-demand diameters ranging from 64mm up to 76mm and 102mm (2 1/2” to 4”), this series is engineered from premium high-alloy steel that undergoes strict military-grade heat treatment. At Bloom Machinery, we don't just supply stock items; our engineering team works directly with your underground blasting crew to configure customized reaming equipment for even larger hole size requirements, lowering your total cost per meter.
