A Countersink features a conical shape on its cutting that allows it to deburr an existing drill hole. The tool also performs countersinking, an activity that is also referred to as post-processing. Countersinking is carried out on an already existing hole in the material. While drilling, shreds of the material, say metal, for instance, remain at the edge of the hole. These shreds or burrs must be removed, or they would interfere with the activity that is to follow. Countersinks help remove the burrs.You can also use this tool to countersink a screw. You then insert the fastener perfectly into the space creating a tight bond. Flat countersinks feature a cylindrical cutting edge. They help in making space for screw heads. The Cross-hole cutter is another type of countersink with a cutting-edge axis of 45 degrees. It also has a drill hole for transporting the chips coming out, resulting in a clean drill-hole.Get the best selection of countersinks from MRO Supply. We stock a wide range of tools
