Down-the-hole (DTH) bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a splined drive for rotating the bit in the ground. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes.

Features of Convex Face
• This face has been designed to offer high penetration rate in soft rock such as shale, limestone etc

• They are recognized for having excellent capability for drilling into moderately consolidated rock conditions

Carbide Design

DTH Bits with hemispherical carbide configuration are capable of drilling in hard rock. Although their penetration rate is slower in comparison to the bits with semi ballistic carbide profile, the bits equipped with these hemispherical buttons have a longer life.

Take advantage of our experience

Over the years we’ve worked on water monitoring bores, water production bores, dewatering bores and artesian bores which means if you’ve got to drill a water bore, we’ve got the skillset to fulfil the brief. Our purpose built DTH bit and DTH hammers and support equipment packages are designed to reduce unwanted downtime which means project slippages will be keep as low as possible.
