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

1

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.

2

Premium Carbide Inserts

Engineered with high-density tungsten carbide buttons that resist severe abrasive wear and micro-chipping.

3

Precision Thermal Insertion

Advanced interference fit technique ensures firmly secured carbide buttons during intense impact loads.

4

Efficient Hole Flushing

Designed with strategically located front and side flushing ports to optimize air/water flow and maximize debris removal.

5

Maximum Energy Transfer

Ensures seamless power transmission from T38 extension rods or speed rods to the rock face, boosting daily drilling output.
