Product Description

 General Introduction

General Introduction
Changsha Tianhe Drilling Teamwhole offers an expansive range of TH bits, varying from 3" to 47" (76mm-1200mm) in diameter. Our DTH bit shanks are compatible with all major 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 advanced heat treatments. The Teamwhole brand boasts various bit face designs including concave, flat, drop center, and convex.

Features:
1. Unwavering quality with extended service life, and minimal abnormal breakage during use.
2. Excellent flushing effect ensures superior drilling rates.
3. Comprehensive quality assurance 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. Works best with low to medium air pressures, offering maximum hole deviation control.

2. Concave Face

Perfect for medium-hard and homogeneous rock formations. Delivers reliable hole deviation control and efficient flushing capacity.

3. Convex Face

Optimized for high penetration rates in soft to medium-hard rocks with low to medium air pressures. This face shape is highly resistant to steel wash, reducing wear on gauge buttons but offers limited hole deviation control.

4. Flat Face

Designed for hard to very hard and abrasive rock formations, especially with high air pressures. Ensures good penetration rates and resistance to steel wash.

 Raw Material

Steel:

Crafted from first-class, special alloy steel known for high strength, heat resistance, and durability.

Carbide:
Primarily uses top-grade tungsten carbide sourced from China.
European-sourced tungsten carbide is also available upon request.
