Screw Digger
Disston Screwdiggers fulfil the same function as Screwsinks but the countersinking part can be slid up and down the drill part of the tool.
This means, for example, that a No.8 Screwdigger can be adjusted to predrill for different lengths of No. 8 Screw.
This set contains 1 each No. 6,8,10 & 12 screwdiggers.
