Where Is Countersinking Used?
Countersinking is used to ensure that flat head screws or fasteners sit flush against the workpiece. Countersinking is used, to make conical holes that match the angled contour on the bottom of flat head screws with conical heads. 6Pcs Countersink Drill Bits Set 1/4” Hex Shank HSS 3 Flute
What Is a Countersink Drill Bit?
A countersink drill bit, also known as a fluted countersink, is a specially designed drill bit that creates a region in the metal that corresponds to the shape of the screw head – which is countersunk. The “V” or conical shape created by the countersink drill bit enables the screw to contact the material on both sides of the screw.
As a result, the screw and the metal form a robust and secure connection. The screw can then be positioned flush with the surface of the metal thanks to the countersink bits’ “V” form. The heads of the screws will lie flush or slightly below the surface when fully tightened. 4 Pieces 90° Angle HSS Countersink Drill Bit Set
