DISSTON 5210 SCREWDIGGER FOR NO.12 SCREWS
.
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 that a No.12 Screwdigger can be adjusted to predrill for different lengths of No. 12 Screw.
Uses 9/64in Drill Bit.
To ensure an acurate fit we suggest you use the same Plug Cutter from the Disston brand.
