Description Drill Bit in Image Not Included. This adjustable diameter carbide tipped “V” bottom countersink is the perfect companion to be used with FISCH or other brands of woodworking drill bits. A very handy tool for the woodworker to drill holes for plugs to hide screws or for flush setting screws into the work project. Being a two piece cutter the user simply slides in a drill bit from 1/8″-5/16″ diameter into the cutter and then tightens the two set screws to hold the bit for depth control and tightness on the shank of the drill bit. This very convenient tool allows the user to do drilling and countersinking in a single operation saving time and labor.
