Excore Bits Enhance Efficiency

摘要

NOT to be outdone, Atlas Copco also introduced a line of diamond coring bits during PDAC, noting that their new Excore bit line is based on the best features of previously successful designs, but offers new design points and matrices to achieve optimized balance between design and metallurgy. According to the company, testing of the bit line before launch was rigorous, with more than 10,000 m drilled in six different markets under varying conditions. One of the Excore design team's principal objectives was higher penetration rate. As explained in the Excore product literature, when drilling in difficult, broken ground with increased risk of hole deviation or lower sample quality, the driller often must decide whether to reduce weight on bit (WOB) or maintain penetration rate.
