T38 Reaming Tools & Guide Systems

Engineered to deliver fast penetration rates and exceptionally straight, clean large-diameter holes. As a specialized rock drilling tools manufacturer, Bloom produces a premium selection of T38 Reaming Tools & Guide Systems utilized to efficiently enlarge boreholes in tunneling and underground drifting. Crafted from high-alloy structural steel paired with tungsten carbide inserts matching the exact grade of internationally renowned tier-one brands, our reaming tools guarantee ultimate wear resistance in punishing strata.

Our integrated manufacturing setup features an entire CNC processing procedure to ensure flawless dimensional consistency across every batch, combined with military-grade heat-treatment protocols that maximize steel body fatigue life. Each reaming bit is precision-engineered with an optimized dual-action profile, integrating a dedicated drill pilot portion and a heavy-duty reamer portion. By precisely machining cutting edges at the end of multiple flushing flutes alongside a calculated relief layout, the system ensures a perfectly stable reaming cutting edge and streamlined debris evacuation. Rather than pushing generic warehouse stock, our technical team collaborates directly with your project engineers to match pilot adapters and reamer configurations to your site's specific geology, driving down your cost per meter.
