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
