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
Applications
• Underground mining
• Quarry benching operations
• Water well drilling
Competitive Advantage
• Main hammer components manufactured from high grade steel
and processed using state-of-the-art CNC machinery and heat
treatment
