Amana 5/64"D DRILL&COUNTERSINK AlTiN 51670

Countersinks are designed to drill down slightly to create a precise starting hole and profile. A secondary drill is then used to achieve the full depth of the workpiece. These tools are not intended for slot routing.

Combination drill/countersinks provide accurate starting positions for secondary drilling operations while also producing precise countersink dimensions for screw heads and similar applications.
