Low Pressure Alloy Steel DTH Hammers For Water Well Drilling ø80 ø156

High Efficiency Low Pressure Alloy Steel Down The Hole DTH Hammers For Water Well Drilling

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
