The popular Secoroc Premium down-the-hole bits, introduced in 1999, are a hard act to follow, but that doesn’t mean that the manufacturer is standing still. ATLAS COPCO SECOROC now offers the Premium Plus DTH bit, which boasts a 10-30% longer life. Added to this reliability is a 5% increase in penetration rates.

The new Premium Plus design has refinements such as a tougher steel grade to resist fatigue. The buttons are repositioned to improve the penetration rate, and they are designed to protrude more, which aids in cuttings removal, less secondary crushing, and easier bit grinding. Finally, to reduce the risk of jamming in the hole, the taper on the bit head is shorter with a larger clearing. Shanking and chunking are practically eliminated, says Atlas Copco.

Premium Plus bits are now available for 5-inch hammers. Bits for 4-inch and 6-inch hammers will be available soon. They come in several configurations such as flat front HD, SpeedBit, convex front with ballistic buttons, concave front, and concave DGR.
