Overall

Down-the-Hole (DTH) hammers are hard rock drilling tools, delivering powerful percussive action directly at the drill bit face. It provides high penetration rates and straight hole drilling in hard rock conditions.

Product Description

PAT-Drill stocks and supplies Halco brand DTH hammer, manufactured in the UK with more than 60 years of experiences in DTH tooling design and manufacture. We complement this with our own manufactured support equipment including stripping clamps, bit spanners, and starter tubes for all DTH hammer sizes.

How It Works:

High-pressure compressed air drives the internal piston mechanism delivering rapid hammer blows directly to the button bit. The percussive action fractures the rock while compressed air flushes cutting up the annulus, maintaining clean hole conditions and cooling the bit

Applications:

Essential for water well drilling, geotechnical investigation, and mineral exploration in hard rock formations including granite, basalt, quartzite, and other crystalline rocks
