Diamond DTH Bit

DTH bit is the key part of DTH drilling, and it is also one of the main consumption parts. The PCD inserts of Changsha 3Better DTH hammer bits have the excellent characteristics of high wear resistance, strong impact resistance, high thermal conductivity, etc. The bit body is specially designed and processed. According to different geological conditions, Changsha 3Better adopts PDC cutters with different performance requirements to achieve application optimization. Compared with traditional tungsten carbide DTH bits, diamond DTH bits have the advantages of increased footage, high drilling efficiency and low cost, so it is an ideal bit for medium-hard rocks.

Bit Type:

Concave Face, Convex Face, Flat face

DTH Bit Inserts Type:

PDC Dome/Round Insert, PDC Dome/Round Insert, PDC Flat Insert

Applications:

mainly used in underground mine mining, open-pit mining, blast furnace opening of steel plant, secondary crushing of mines, tunneling and other fields.

Advantages:

1.The hardness and toughness of the bit are increased by 30% by using diamond PDC buttons.
2. Unique design, drilling speed is increased by 20%, life increased by more than 30%.
3. The imported high-grade steel is selected as the bit body to ensur

Product Introduction

Diamond DTH Bit Types

1. Concave Face

This bit face is specifically for medium hard and homogeneous rock formations. Good hole deviation control and good flushing capacity.

2. Convex Face

This face is for high penetration rates in soft to medium-hard with low to medium air pressure. It is the most resistance to bit body, and may reduce the load and wear on gauge inserts, but poor hole deviation control.

3. Flat face

This kind of face sharp is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates a resistance to bit body.

Compared with traditional carbide DTH Bit, Diamond DTH Bits have the following advantages:

1. The service life of the Diamond DTH Bit is increased by more than 6 times;
2. The overall tool cost of the operation decreased by more than 30%;
3. The production efficiency of the operation is increased by more than 20%;
4. It can better maintain the quality of the well hole;
5. Make the target application that was impossible to complete once become possible;
6. Reduce the frequency of tool replacement and reduce the labour intensity of workers.
