Longer tool life is becoming an expectation as you look to improve efficiency and reduce your cost per meter. We've reinvented face drill bit design to deliver you unprecedented improvements in durability, safety and productivity in your most abrasive rock conditions. Our Sandvik top center drill bits for face drilling and bolting were developed to solve persistent tool life problems in particularly abrasive rock. Featuring our latest carbide grade, GC80, the innovative new top center bits feature a raised front, making room for more inserts as well as larger flushing holes and bailing grooves. Elevating two or three front buttons a few millimeters above the gauge buttons located on the periphery of the bit protects the gauge from wear, extending bit life.
