Review on Champion Proline 8700 24 24 Inch Extension by Phil Kuebler

Well made and comes with two set screws to hold the drill in place. No hex wrench is supplied and requires either a 3mm or 7/64 hex wrench for the set screws. The downside to using it is the 7/8 inch diameter shank that it attaches to the auger. For through holes, a 1" or larger diameter drill bit must be used.
