Many meters supply all kinds of high

Type of down-the-hole drill bits: The products are divided into two series of down-the-hole drill bits, low-pressure down-the-hole drill bits and high-pressure down-the-hole drill bits. High-pressure down-the-hole drill bits are matched with high-pressure down-the-hole drilling rigs. They are suitable for drilling hard rock formations that require large impact power. The structural characteristics are: fast drilling speed, good powder discharge effect, and better cooling. High wind pressure drill head structure: boss spring tooth type platform type concave platform type.

Tungsten Carbide Plates

150 high wind pressure down-the-hole drill product features:

Long service life of the drill bit: strength ≥2800N , Hardness (HRA)≥92.

◆ It has the advantages carbide rodsof high drilling quality, fast excavation speed, multiple grinding, and long service life.
Spline connection uses 55A impactor.

Features of down-the-hole drills: fast drilling speed! High efficiency, low labor intensity and high cost performance!

Usage of down-the-hole drill bits: Widely used in earthwork engineering, mining, water well drilling, construction engineering, water well drilling, side pillar support, etc. The down-the-hole drill bit is a kind of drill bit used in conjunction with the down-the-hole impactor, which is used for drilling operations through splines and the impactor. The DTH drill bit is used in conjunction with the DTH impactor, which has the characteristics of flat drilling, high speed, and deep hole drilling. Therefore, it has been widely used in recent years.
