Product Description

 General Introduction

General Introduction
Changsha Tianhe Drilling Tools and Machinery Co., Ltd. proudly presents a versatile range of Teamwhole brand DTH bits, with diameters spanning from 3 inches to 47 inches (76mm-1200mm). Our DTH bits are compatible with all major international shank designs, including BR, MACH, DHD, COP, IR, NUMA, SD, QL, and MISSION.
Our DTH bits are meticulously crafted from premium alloy steel and undergo advanced heat treatment processes, ensuring exceptional durability and performance. Teamwhole DTH bit faces are available in various designs, including concave, flat, drop center, and convex, to suit different drilling conditions and requirements.

Features:
1. Exceptional quality and longevity, with minimal risk of unexpected breakage during operational life.
2. Superior flushing effect that guarantees enhanced drilling rates.
3. Rigorous quality assurance and compensation policies.

Bit Face Shape Selection:

1. Drop Center Bit

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

2. Concave Face

A versatile bit face designed for medium-hard and homogeneous rock formations. Provides excellent control over hole deviation and ensures efficient flushing.

3. Convex Face

Perfect for high penetration rates in soft to medium-hard rock with low to medium air pressures. This design offers superior resistance to steel wash and reduces load and wear on gauge buttons, albeit with less control over hole deviation.

4. Flat Face

Best suited for hard to very hard and abrasive rock formations, particularly in high air pressure applications. Delivers robust penetration rates and exceptional resistance to steel wash.

 Raw Material

Steel:

Constructed 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 carbide options are also available.
