Digga Auger Bits

Digga offers earth auger bits, rock auger bits, tree planting bits, and combination bits. Each type is engineered for specific soil conditions from soft loam to solid rock and frozen ground.

Use standard earth bits for clay, loam, and sandy soil. Switch to carbide-tipped rock bits for hard ground, shale, and frost. Digga's bit selection guide on each product page helps match bit to soil.

Digga auger bits use a standard hex shaft or round shaft connection depending on the drive unit. Confirm your Digga auger drive's output shaft size and type before selecting a bit.

Yes. Digga auger bits feature bolt-on teeth and replaceable pilot points that swap out in minutes. Replacing worn teeth restores full cutting performance without buying an entirely new bit.

A 6 to 9 inch bit fits standard round fence posts, while 12 inch bits suit 4x4 and 6x6 square posts. Oversize the hole slightly to allow room for concrete backfill around the post.
