Machine Counterbore

Machine counterbores are a type of cutting tool used in machining operations. They are part of the supply class "Drill Bits, Counterbores, And Countersinks: Hand And Machine" in the supply group "Hand Tools".

A machine counterbore is designed to create a flat-bottomed hole with a larger diameter than the original hole. It is commonly used to create a recess or counterbore for a screw or bolt head to sit flush with the surface of the material being drilled.

Machine counterbores typically consist of a cylindrical body with a cutting edge at the bottom and a shank at the top. The cutting edge is usually made of high-speed steel or carbide, which allows for efficient cutting and long tool life. The shank is designed to fit into a drill press or other machine tool for precise and accurate drilling.

Machine counterbores come in various sizes and configurations to accommodate different hole diameters and depths. They are commonly used in metalworking, woodworking, and other industries where precise and professional drilling is required.

When using a machine counterbore, it is important to follow proper drilling techniques and safety precautions to ensure accurate and safe drilling operations.
