RC4 - Combination Earth and Rock Augers

RC4 augers are available with a range of different teeth options to suit most ground conditions including earth, hard soils, shale, clay, and permafrost. Basically, with the RC4, you get all the benefits of the A4 plus the superior penetrating ability of the B7 taper tooth head. The RC4 comes complete with all purpose taper teeth perfect for combination drilling in all conditions - from earth to medium rock, providing a clean hole every time. RC4 teeth are easy to install and remove with Digga's ingenious knock in, knock out tooth locking system which eliminates the need to use extra tools to remove the teeth.
