Product Description
In DTH hammers, 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 hammers a nearly constant penetration rate regardless of hole length. 

Working with DTH drilling pipe and DTH drill bit, our product range covers most divers applications in mining, natural resources exploration, water wells, quarries and civil works.

This low air pressure DTH hammers are for holes of small to medium size drilling diameters.
They work in low pressure range, capable of drilling shallow to medium hole lengths.
Low air pressure hole Diameter: 65-220mm
