Description

DHD3.5 DHD340 DHD350 DHD360 Low Pressure 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
