Product Description

 General Introduction

 

General Introduction
Changsha Tianhe Drilling Tools and Machinery Co., Ltd., under its prestigious brand Teamwhole, offers an extensive range of TH bits, covering diameters from 3" to 47" (76mm to 1200mm). These DTH bits are compatible with all international brands such as BR, MACH, DHD, COP, IR, NUMA, SD, QL, MISSION, and more.
Our DTH bits are meticulously crafted from premium alloy steel and subjected to advanced heat treatment processes. The Teamwhole brand DTH bits are available in various face designs, including concave, flat, drop center, and convex, ensuring versatility for different drilling conditions.

Features:
1. Exceptional quality with a prolonged service life and minimal instances of abnormal breakage during its lifespan.
2. Superior flushing efficiency guarantees a high drilling rate.
3. Comprehensive quality assurance and compensation policies.

Bit Face Shape Selection:

1. Drop Center Bit

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

2. Concave Face

A versatile bit face suited for medium-hard and homogeneous rock formations. Offers excellent hole deviation control and efficient flushing capacity.

3. Convex Face

Designed for high penetration rates in soft to medium-hard rock formations with low to medium air pressures. Provides maximum resistance to steel wash, potentially reducing the load and wear on gauge buttons, albeit with lower hole deviation control.

4. Flat Face

Optimal for applications in hard to very hard and abrasive rock formations under high air pressures. Delivers excellent penetration rates and resistance to steel wash.

 Raw Material

 

Steel:

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

Carbide:
Utilizes top-grade tungsten carbides sourced from China.
Tungsten carbide from European suppliers is also available upon request.
