Flat Face

An universal design, especially for hard and abrasive rock formation. 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 rate and resistance to steel wash.

 

Dome/Hemispherical Buttons

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

Semi-Ballistic/Parabolic Buttons

Excellent penetration rate, but only suited to medium hard and not so very abrasive rock formation.
