The XO100 and XT100 extensions let you drill deeper with a Digga RC10, RC11 or DR11 auger, on 15 to 30 tonne excavators with drives up to the PD50.

Outer extensions (XO100) and telescopic inner extensions (XT100), each from 1,000 to 4,000 mm.
Rated to 40,000 Nm. The outer has a 168 mm body with an 11 mm wall, and the inner is 100 mm square solid bar.
100 mm square hub, so no adaptor is needed. Eyelets for lifting, tie-down and hanging the auger in the hole while you add a length.
Australian made, with a welded hub and shaft for a straighter hole.

Every length is made to order, and we'll confirm the lead time when you order. Inners won't fit inside smaller augers. Tell us your drive and auger when you order and we'll check the extension suits them before anything is ordered.
