RC11 Combination Earth & Rock Auger Bits

The RC11 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.

RC11 auger bits are available with a range of different teeth options to suit most ground conditions including earth, hard soils, shale, clay, and permafrost. With the RC11, you get all the benefits of the RC10 plus the superior penetrating ability of the larger BB tooth head and extra havy duty TTL teeth.

RC11 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.
