Boart Longyear has successfully created a chemical bond between diamond and matrix, which acts stronger than the diamond itself.

These two qualities in a bit are hard to come by. Usually, a bit that cuts faster gets used up faster – which means more tripping to change the bit. The new Longyear bits seem to have the right balance. It’s important to select the right bit for the type of rock encountered. Longyear bits make that easier to do. I highly recommend the new Longyear bits – they have improved penetration rates, productivity and outlast any other bit I’ve used.”  \n-Robert Jex, Division Manager US North Coring  \n“Boart Longyear Color series bits not only penetrate rock faster, they last well beyond the other diamond bits I’ve used throughout my 32-year career.”  \n-Mike Reedy, Division Manager, DS-Southwest Coring  \nLONGYEAR™ BITS  \nIncreased Productivity  \nThe Longyear Bits are similar to large diamond bits, but with the easy, smooth drilling characteristics drillers prefer. This means increased productivity throughout the entire operation, and ultimately more core.  \nHigher Penetration Rate  \nTo support higher penetration rates, the new Longyear™ formulas are combined with anew, more open, express geometry. Tapered intermediate waterways improve flushing and prevent accumulation of debris. Designed for fast cutting in competent ground, the new express geometry is available in our 16mm crown heights to maintain bit life at higher cutting speeds.  \n1  \n2  \n3  \n1 RAZORCUT™  \nThe unique Razorcut™ protrusions on the face of the bit contain diamonds that enable the bit to begin cutting right out of the box – even in the softest ground. The arrangement of these protrusions also improves the tracking and balance in the hole when drilling begins.  \n2 LONGYEAR™ MATRIX*  \nAfter significant research, using novel metallurgy, Boart Longyear has successfully created a chemical bond between diamond and matrix, which acts stronger than the diamond itself. The increased diamond projection and improved face flushing create a bit with more versatility, higher penetration rates and longer life, similar to large diamond bits, but with the easy, smooth drilling characteristics drillers prefer. This means increased productivity throughout the entire operation, and ultimately more core.  \n3 EXPRESS GEOMETRY  \nTo support higher penetration rates, we have combined the new Longyear™ formulas with a new, more open express geometry. Tapered intermediate waterways improving flushing and prevent accumulation of debris.
