Increase the drilling depth of your auger bit with a Digga extension.

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.
• Telescopic Design (XT25 & XT40) – A telescopic design makes it easier to drill deeper as well as easier to transport. Inner extensions can be slid inside outer extensions and augers saving space and reducing loading time.
