Every single one of our excavator augers is built to accommodate the higher hydraulic operating pressures of modern machines. Besides that, you can be sure our augers are of industrial-grade quality and crafted to last. Check out these other aspects of our product lineup as well: With any Premier auger, there's no requirement for a third drain line. Our high torque drive units work magnificently in even the toughest digging conditions. We offer mounting brackets to work with pin-on buckets, OEM quick couplers, aftermarket couplers, and custom mounting brackets. Our mounts actually cradle the drive unit and auger bit to keep them secure when your excavator's on the move. Our output shafts are available in 2-inch hexagon, 2 1/2-inch hexagon, 2-9/16-inch round, 3-inch hexagon, and 4-inch square configurations. The types of augers listed in the chart below are typical of those used on excavators. If these won’t accommodate you, rest assured that Premier can engineer and custom-build precisely the auger you need.
