 General Introduction

Changsha Tianhe Drilling Tools and Machinery Co., Ltd.

General Introduction

Changsha Tianhe Drilling Teamwhole specializes in the production of high-quality DTH (Down The Hole) bits. Our range of TH bits covers diameters from 3" to 47" (76mm-1200mm). Our DTH bits are compatible with international brands such as BR, MACH, DHD, COP, IR, NUMA, SD, QL, MISSION, and more.

Features

• Reliable quality with a long service life, rare abnormal breakage during use.
• Good flushing effect to ensure high drilling rate.
• Strict quality warranty and compensation rules.

Bit Face Shape Selection

1. Drop Center Bit: Designed for high penetration rates in soft to medium hard and fissured rock formations. Suitable for low to medium air pressures and provides maximum hole deviation control.
2. Concave Face: An all-around application bit face specifically designed for medium hard and homogeneous rock formations. Offers good hole deviation control and flushing capacity.
3. Convex Face: Ideal for high penetration rates in soft to medium-hard rock formations with low to medium air pressures. Most resistant to steel wash but poor hole deviation control.
4. Flat Face: Suitable for hard to very hard and abrasive rock formations with high air pressures. Provides good penetration rates and resistance to steel wash.
