We put our metallurgists to work with a simple request – invent the most durable steel we’ve ever used in a drill bit (and our history dates back to 1873...) They came up with 15 percent higher wear resistance and 10 percent higher fatigue strength.
The durability of the buttons is crucial to high drilling productivity. The premium patented treatment, used on our spherical and Trubbnos buttons, makes them tougher and more wear resistant. For you, that means more drill meters between regrinds.
The drillbit can be delivered with both spherical buttons and Trubbnos. Trubbnos is our new and innovative trapezoid-shaped buttons, which offer longer service life and improved penetration rate than semi-ballistic buttons. (Trubbnos, by the way, is Swedish for flat nose, an indication of the geometry of the new buttons.)
