How to Choose the Right DTH Drill Bit
Choosing the right DTH drill bit depends on the rock hardness, drilling diameter, DTH hammer size and required penetration rate. For hard and abrasive rock formations, wear resistance and suitable carbide button design are especially important. Different face designs and shank types can also affect drilling efficiency and hole stability. Contact our team for help selecting a suitable DTH drill bit for your drilling conditions and equipment.
Carbonized Button Shape
Domed / Round Button
Usually used as gauge buttons on DTH bits, ideal for very hard and highly abrasive formations.
Parabolic / Semi-Ballistic Button
Commonly used as gauge and front buttons, suitable for hard and medium-abrasive rock formations.
Ballistic Button
Usually used as front buttons for medium-hard and medium-abrasive formations, and can also serve as gauge buttons in softer rock.
