    Bit life and rate of penetration are the most important criteria in selecting the right bit for a particular application. In most cases, the focus is on productivity, so the fast cuttings removal features (Convex/Ballistic designs) are preferable, to ensure the buttons are cutting clean, with the minimum of recrushing.


    In hard and abrasive formations, however, the flat front design offers best bit life, having strong gauge rows with large spherical buttons which are easy to regrind and maintain.Each bit is made from quality alloy steel, and has been precision machined to produce a perfect body, heat treated to the requrired hardness, given surfacure compression for fatigue resistence , and fitted with precision buttons manufactured in-house.

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 the 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.
