Detailed Product Description

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: High 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
