Product Description

 General Introduction

Introducing Changsha Tianhe Drilling Tools and Machinery Co., Ltd.
Changsha Tianhe Drilling Teamwhole offers an extensive range of TH bits, with diameters spanning from 3" to 47" (76mm to 1200mm). Our DTH bits are compatible with all internationally recognized shank brands such as BR, MACH, DHD, COP, IR, NUMA, SD, QL, MISSION, and more.
Crafted from premium alloy steel and subjected to advanced heat treatment processes, our DTH bits under the Teamwhole brand exhibit different face types including concave, flat, drop center, and convex.

Key Features:
1. Unwavering in quality, extended service life, and minimal instances of abnormal breakage during usage.
2. Superior flushing efficacy ensuring enhanced drilling speeds.
3. Comprehensive quality assurance and compensation policies.

Choosing the Right Bit Face Shape:

1. Drop Center Bit

Ideal for achieving high penetration rates in soft to medium-hard, fissured rock formations under low to medium air pressures. Ensures maximum control over hole deviation.

2. Concave Face

A versatile bit face designed specifically for medium-hard, homogeneous rock formations. Provides excellent hole deviation control and superior flushing capability.

3. Convex Face

Perfect for high penetration rates in soft to medium-hard rocks with low to medium air pressures. Notable for its resistance to steel wash and reduced load and wear on gauge buttons; however, it offers lesser control over hole deviation.

4. Flat Face

This face shape is tailored for hard to very hard, abrasive rock formations, performing exceptionally well under high air pressures. Delivers robust penetration rates and resistance to steel wash.

 Raw Material

Steel Composition:

Manufactured from first-class special alloy steel, renowned for its high strength, heat resistance, and wearability.

Carbide Composition:
We typically use superior tungsten carbides sourced from China.
European tungsten carbide options are also available upon request.
