 General Introduction

Product Description

Changsha Tianhe Drilling Tools and Machinery Co., Ltd.

DTH Bits

Changsha Tianhe Drilling Teamwhole is a leading manufacturer of DTH bits. Our range of TH bits is available in various sizes, ranging from 3" to 47" (76mm to 1200mm) in diameter. Our DTH bits are compatible with international brands such as BR, MACH, DHD, COP, IR, NUMA, SD, QL, MISSION, and more.

Our DTH bits are made from high-quality alloy steel and undergo advanced heat treatment, ensuring their reliability and long service life. The bit faces are available in different shapes, including concave, flat, drop center, and convex, to suit various drilling needs.

Features:

1. Reliable quality and long service life, with rare abnormal breakage during operation.


2. Good flushing effect for high drilling rates.


3. Strict quality warranty and compensation rules.

Bit Face Shape Selection:

1. Drop Center Bit: Ideal for high penetration rates in soft to medium-hard and fissured rock formations. Suitable for low to medium air pressures and offers maximum hole deviation control.


2. Concave Face: All-around application bit face specifically designed for medium-hard and homogeneous rock formations. Provides good hole deviation control and flushing capacity.


3. Convex Face: Offers high penetration rates in soft to medium-hard formations with low to medium air pressures. Provides resistance to steel wash and reduces load and wear on gauge buttons. However, it has poor hole deviation control.


4. Flat Face: Suitable for hard to very hard and abrasive rock formations with high air pressures. Offers good penetration rates and resistance to steel wash.
