The highest caliber gauge protection in the industry! Boart Longyear's Alpha bit range now features the Magnum Gauge. Natural diamonds have been replaced with PCD (polycrystalline diamond) pins for superior coverage to guarantee: a value-added standard at no extra cost the highest performing bits for all drilling applications extended bit life longer lasting bit gauge protection and stabilization to provide improved reaming shell life incorporates the cutting edge of diamond technology - metal coated diamonds. The metal coating allows the diamond to be retained in the crown for a longer period of time by protecting the diamond from oxidation and surface degradation during the manufacturing process. Extensive research proves that coating the diamond with specific metals inhibits premature "pull-out" of the diamond and increases the number of cutting edges exposed to the rock. Allowing more of the diamond to cut for a longer period of time results in a significant improvement in the cutting speed and life of Alpha bit.
