Product Description

 General Introduction

General Introduction
Changsha Tianhe Drilling Teamwhole is capable of producing an extensive range of TH bits, with diameters spanning from 3"-47" (76mm-1200mm). These premium DTH bits are compatible with a vast array of international brands, including BR, MACH, DHD, COP, IR, NUMA, SD, QL, MISSION, and more.
Our DTH bits are crafted from superior quality alloy steel and undergo advanced heat treatment processes. The Teamwhole brand offers a variety of DTH bit face designs, such as concave, flat, drop center, and convex, catering to diverse drilling requirements.

Features:
1. Exceptional quality and durability, ensuring a long service life with minimal incidents of abnormal breakage.
2. Superior flushing efficiency, guaranteeing a high drilling rate.
3. Comprehensive quality warranty 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. Suited for low to medium air pressures, it provides excellent hole deviation control.

2. Concave Face

A versatile bit face designed for medium-hard, homogeneous rock formations. It offers reliable hole deviation control and efficient flushing capacity.

3. Convex Face

Designed for high penetration rates in soft to medium-hard rock formations using low to medium air pressures. This shape is highly resistant to steel wash, potentially reducing wear on the gauge buttons, though it offers less control over hole deviation.

4. Flat Face

Best suited for hard to very hard and abrasive rock formations under high air pressures. It ensures good penetration rates and resistance to steel wash.

 Raw Material

Steel:

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

Carbide
We commonly use premium tungsten carbides sourced from China.
European tungsten carbide options are also available.
