The Flat face is a very aggressive design for most drilling applications, especially in fractured and fissured rocks with changing formations. Having the Flat face design helps prevent bit plugging in softer zones as there is more carbide to the surface of the rock. This design is a very simple and robust design well suited for hard rock formations.
The Concave face style is very common within the market as it is very effective for all rock conditions particularly in the deep-hole drilling. The Concave design is very effective if hole alignment is a priority due to its inverted pilot.
The Convex face is a very strong design when used in hard abrasive rock. This face is also well balanced, fast drilling and has a good life span. The design of the convex face also offers increased body support for the gauge carbide.
The Ballistic insert is more suitable for low abrasive rock through less consolidated drilling formations. The Ballistic buttons however yield high penetration rates and efficient rock breakages.
When it comes to selecting you inserts you can’t go far wrong with the Domed insert this is a strong rugged shape with a good life span, throughout all conditions be it soft, medium or hard abrasive rock and deep hole drilling. This Insert provides excellent penetration rates through all types of formation.
