This is an universal design, especially for hard and abrasive rock formation. So typically, flat face with hemispherical buttons design is the most popular choice.

This kind of face shape is suitable for hard to very hard and abrasive rock formations in application with high air pressure. Good penetration rates an resistance to steel wash.

Dome/Hemispherical Buttons

Universal buttons for all rock formation, best suited to hardest and very abrasive rock formation.

Parabolic/Semi-Ballistic Button

It is usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.

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.
