T38 64mm Retrac Thread Button Bit for Underground Tunneling Quarrying Rock Drilling Mining
T38-64mm Threaded Retrac Button Bit
Advanced Hydraulic Rock Drilling Tool for Underground Mining, Tunneling, and Quarrying Operations
Product Overview
The T38-64mm Threaded Retrac Button Bit is an advanced hydraulic rock drilling tool designed for underground drifting, tunneling, and production bench drilling. Crafted from premium alloy steel and ultra-wear-resistant tungsten carbide buttons, this 64mm drill bit offers exceptional impact strength, faster penetration rates, and maximum service life in medium-to-hard rock formations.
Featuring an advanced Retrac (retraceable) body structure and optimized flushing system, it helps maintain hole straightness while making bit retrieval significantly easier in fractured or sticky rock conditions, reducing downtime and lowering overall cost-per-meter.
Main Applications
Underground Mining & Tunneling
Ideal for high-efficiency drifting, cross-cut operations, and mine gallery development.
Production & Bench Drilling
Suitable for long-hole production drilling in open-pit mines and quarry operations.
Civil Infrastructure Projects
Used for foundation drilling, slope stabilization, and highway rock excavation.
Fractured Rock Drilling
Specially efficient in broken, hard, or fractured rock formations where hole deviation and bit jamming are concerns.
Key Features & Advantages
Retrac Design for Easy Retrieval
The specialized guide ridges on the bit body allow for smooth reverse drilling, effectively preventing bit jam in loose or broken rock strata.
Premium Carbide Inserts
Engineered with high-density tungsten carbide buttons that resist severe abrasive wear and micro-chipping.
Precision Thermal Insertion
Advanced interference fit technique ensures firmly secured carbide buttons during intense impact loads.
Efficient Hole Flushing
Designed with strategically located front and side flushing ports to optimize air/water flow and maximize debris removal.
Maximum Energy Transfer
Ensures seamless power transmission from T38 extension rods or speed rods to the rock face, boosting daily drilling output.
