Air Pressure Mining Well Drilling Tools Down The Hole DTH Hammers
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
Product Description
1) Specific heat treatment standards
2) Premium hardened steel alloy
3) High-grade cemented tungsten carbide buttons.
