Introduction
Middle air pressure DTH hammer BR1 BR2 BR3
Our tools are widely used in different drilling applications including mining, quarrying, water well drilling, geotechnical industries and etc.
In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.
DTH Hammer Types coverage: DHD/COP/HD/IR/TD/COPROD/QL/SD/Mission/Numa/Mach etc.DTH Bit Size range: 2”-24”(76-775mm)
