Disston Screw Digger Set tb24c2
	Disston Screwdiggers fulfil the same function as Screwsinks but the countersinking part can be slid up and down the drill part of the tool. Ideal for drilling, countersinking and counterboring in one operation. For Example - This means 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 To ensure an accurate fit we suggest you use the same Plug Cutter from the Disston brand.
