Product Description

 General Introduction

General Introduction
Changsha Tianhe Drilling Teamwhole offers an extensive range of TH bits that cater to various needs, ranging from 3"-47" (76mm-1200mm) in diameter. These DTH bits are compatible with all major international brands including BR, MACH, DHD, COP, IR, NUMA, SD, QL, MISSION, and more.
Crafted from premium alloy steel and enhanced through advanced heat treatment processes, Teamwhole brand DTH bits feature a variety of face designs, such as concave, flat, drop center, and convex.

Features:
1. Exceptional quality and extended service life, with rare occurrences of abnormal breakage during use.
2. Efficient flushing effect, ensuring a high rate of drilling.
3. Stringent quality warranty and compensation policies.

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 provides excellent hole deviation control.

2. Concave Face

A versatile bit face specifically designed for medium-hard and homogeneous rock formations. Offers good hole deviation control and effective flushing capacity.

3. Convex Face

Designed for high penetration rates in soft to medium-hard formations with low to medium air pressures. It is highly resistant to steel wash and can reduce load and wear on the gauge buttons, though it offers less control over hole deviation.

4. Flat Face

This face shape is ideal for hard to very hard and abrasive rock formations, especially in high air pressure applications. It provides good penetration rates and strong resistance to steel wash.

 Raw Material

Steel:

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

Carbide:
Utilizes the finest tungsten carbides sourced from China.
European tungsten carbide is also available upon request.
