Product Description

 General Introduction

General Introduction
Changsha Tianhe Drilling Teamwhole boasts the capability to manufacture an extensive range of TH bits, spanning diameters from 3"-47" (76mm-1200mm). Our DTH bits shank is compatible with all international brands including BR, MACH, DHD, COP, IR, NUMA, SD, QL, MISSION, and more.
Our DTH bits are crafted from premium alloy steel and undergo advanced heat treatment processes. The Teamwhole brand DTH bits offer various face designs such as concave, flat, drop center, convex, and more.

Features:
1. Superior quality with an extended service life, exhibiting minimal abnormal breakage during use.
2. Excellent flushing effect to ensure a high drilling rate.
3. Rigorous quality warranty and comprehensive compensation rules.

Bit Face Shape Selection:

1. Drop Center Bit

Ideal for high penetration rates in soft to medium-hard and fissured rock formations. Operates efficiently under low to medium air pressures, ensuring 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 at low to medium air pressures. Highly resistant to steel wash, reducing the load and wear on gauge buttons, though it offers limited hole deviation control.

4. Flat Face

This face shape is perfect for hard to very hard and abrasive rock formations, especially under high air pressures. It provides good penetration rates and resistance to steel wash.

 Raw Material

Steel:

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

Carbide:
We utilize the finest tungsten carbides sourced from China.
European tungsten carbides are also available.
