Today’s mining operation focus on producing the largest amount of tonnage at the lowest possible cost. To make ever-increasing production demands, mine operators must keep their equipment running with the last technology. They simply cannot afford to wait on roof-bolting crews using outdated equipment and technician while continuous miners site idle.  The carbide bits, which have been used for decades, these bits easily dull while drilling and needs to be replaced frequently, slowing roof bolters and limiting production. This ongoing maintenance problem slows the mining process, decreases production and creates safety concerns as miners scramble under unsupported areas to change out roof bolting bits. So mining operators can continue.
