Air Pressure Mining Well Drilling Tools Down The Hole DTH Hammers
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.
• Small to medium size drilling diameters
• Works in low pressure range, capable of drilling shallow to
medium hole lengths
Type: Efficient High Pressure DTH Hammer

1) Specific heat treatment standards
2) Premium hardened steel alloy
3) High-grade cemented tungsten carbide buttons.
