Every bit seat is not created equal; some are much better than others. A new, advanced bit seat is available to mining companies that are so hardy operators have to replace worn out bits about 50 times less often. These bits also significantly reduce bolting time, which increases operators’ efficiencies on the drill. These advanced bit seats are able to maintain the gauge of the hole and adapt to most shapes of drill steel extension rods. They also increase the strength and wear resistance while eliminating irregularities and hole rifling. They also make the installation of standard bolts, cable bolts and resin cartridges much easier to install.
