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.
