Hand Counterbore

Hand Counterbores are tools used for creating a recessed hole, known as a counterbore, in a material. They are part of the supply class Drill Bits, Counterbores, And Countersinks: Hand And Machine in the supply group Hand Tools.

Counterbores are typically used when a fastener, such as a screw or bolt, needs to be flush with or below the surface of the material. The counterbore creates a flat-bottomed hole with a larger diameter than the fastener head, allowing it to sit below the surface.

Hand Counterbores are designed to be used manually, without the need for a power tool. They usually consist of a cylindrical body with a cutting edge at the bottom and a pilot drill at the center. The pilot drill helps guide the counterbore into the material, ensuring a precise and accurate hole.

Hand Counterbores are commonly used in woodworking, metalworking, and other applications where a clean and professional finish is desired. They are available in various sizes to accommodate different fastener sizes and can be purchased individually or as part of a set.
