Product Description

DTH hammer Bits are one of our main products. After mang years search, we have rich experience in development and manufacturing high quality products, which adopted high-quality raw materials, advanced technology and passed through strictly inspection.

DTH hammer bits / Down-the-hole caride bits were used for blast hole drilling. Which is working with DTH hammer, mainly applied in Mining, Marble quarry or well drilling and other construction projects.
 

Characteristic

1. High and low air pressure down-the-hole drill bits:

A: Low air pressure hole Dia.:65-220mm

B: High air pressure hole Dia.:85-305mm

2. Our DTH Bit can be suitable for many types of DTH Hammer, such as XL, Mission, COP, IR, Mach, Demag, SD, Bulroc, Halco Mach, Digger etc
