Roschen offers standard and heavy duty hollow stem augers in five foot lengths (custom lengths available), sizes ranging from 2 1/4" through 10 1/4" (identified by the auger I.D.) and with a 2 key or 3 key drive system. Diedrich and Acker octagonal style hollow stem augers are available upon request. Standard duty augers are generally recommended for shallower drilling, (less than 70'), and for lower torque drill rigs. Heavy duty augers feature heavier tool joints and larger auger bolts and drive keys. HD augers are generally recommended for drilling in excess of 70', and for higher torque drill rigs. All augers are quality crafted from premium materials and include continuous hard faced flighting, to ensure performance and longevity in even the most demanding drilling conditions. Questions?
