Boart Longyear upgrades and expands Stage diamond coring bits for rapid exploration

first_imgBoart Longyear has upgraded and expanded its Stage® diamond coring bit product line. The new bits include engineering upgrades to the patented Stage3 waterways, a full selection of Stage bits with a 16 mm crown and an optional face-discharge feature. The company says that “since its release in 2007, the Stage3 diamond coring bit remains the world’s tallest, with a crown height of more than 25 mm. Its patented design delivers better penetration rates, longer active drilling in the hole and fewer rod trip-outs, increasing shift capacity and overall meters drilled.”“The new bits provide a benchmark for reliable, cost-effective, high-productivity drilling in any ground condition,” said Monika Portman, Product Manager for coring products with Boart Longyear. “The new design features an expansion of our patented window to improve productivity, a revised window layout to increase strength and our new patent-pending RazorCutTM face design, which provides the driller with a ready-to-cut bit right out of the box. The 16 mm model includes the upgraded Stage technology and is designed to give our customers more choice when operating at shallower target depths.”Upgrades to the Stage design include windows with rounded corners for greater durability. The new windows increase resistance to damage caused by debris in fractured ground conditions. The windows also feature a new Twin-TaperTM design to increase wear-resistance and boost performance of the bit. The Stage windows taper inward to create more material on the window’s inner diameter, increasing material strength and product life. In addition, the tapered windows cause high fluid velocity in the inner diameter resulting in better flushing of fluids, cuttings, and debris.The Stage windows are now positioned to rotate in the opposite direction of rod rotation, creating more surface material which further increases the strength of the crown, maximizing performance in all ground conditions.last_img
