T38 Reaming Drill Bits

T38 Reaming Drill Bits: High-Performance Tools for Precision Rock Drilling

In demanding rock drilling applications, the right tools make all the difference. T38 reaming drill bits are engineered to deliver high penetration rates, precise borehole enlargement, and superior durability in harsh geological conditions. Whether in mining, tunneling, or civil engineering, T38 reaming drill bits have become the go-to solution for professionals who require consistency, power, and accuracy.

What Are T38 Reaming Drill Bits?

T38 reaming drill bits are specially designed tools used to enlarge pre-drilled pilot holes during rock drilling operations. Built to connect with T38 threaded drill rods, these bits are ideal for medium to hard rock formations. Their design ensures smooth reaming, excellent energy transmission, and extended service life—making them highly reliable in underground and surface drilling environments.

Key Features of T38 Reaming Drill Bits

1. High-Quality Tungsten Carbide Inserts
   Each T38 reaming drill bit is equipped with top-grade tungsten carbide buttons, providing excellent wear resistance and superior impact strength for consistent cutting performance.

2. Robust T38 Threaded Connection
   The T38 thread standard guarantees a tight, secure fit with drill rods, minimizing energy loss and vibration. This secure connection allows for stable drilling even in extreme conditions.

3. Optimized Bit Face Design
   The face geometry of T38 reaming drill bits—available in flat face, drop center, or ballistic configurations—is carefully designed to suit various rock hardness levels and drilling strategies.

4. Multiple Diameter Options
   T38 reaming bits are commonly available in diameters ranging from 76mm to 127mm, accommodating different hole size requirements in mining and construction projects.

Applications of T38 Reaming Drill Bits

T38 reaming drill bits are widely used in the following industries:

• Underground Mining: For stope development, production drilling, and rock bolt installation.

• Open-Pit Mining: Ideal for pre-split and production hole enlargement.

• Tunneling Projects: Ensuring accurate hole sizes for blasting and support systems.

• Geotechnical Engineering: Used in rock reinforcement and slope stabilization applications.

No matter the project scope, T38 reaming drill bits deliver reliable performance, optimal hole straightness, and minimal deviation—critical for operational safety and precision.
