Available for drive units with 2" hex, 2.5" hex, 3" hex, and 100mm square shafts, Digga's outer & inner extensions come in sizes ranging from 2', 3', 4', 6', 8' and 10' lengths.

Features:

• Easy fit design - Digga auger extensions provide you with an easy fit design solution with no adapters required, helping you connect and disconnect your augers faster.
• Reduce excess play - With a welded hub and shaft, these auger extensions reduce excess play in the connections, ensuring you drill a straighter hole.
