High Efficiency Low Pressure Alloy Steel Down The Hole DTH Hammers For Water Well Drilling
Low Pressure Alloy Steel DTH Hammers For Water Well Drilling ø80 ø156
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
Color: Based on Customer requirements
Material: Tungsten carbide and high strength alloy steel
Processing: CNC milling and proprietary heat treatment process
Type: Low Pressure DTH Hammer
