Screwsinks are used for drilling, countersinking and counter-boring in one operation. The countersinking part can be slid up and down the drill part of the tool by means of a hexagon key to suit the depth of hole being drilled .

To ensure an accurate fit we suggest you use the corresponding plug cutter from the Faithfull range.
