Counterbores

Counterbores are precision tools extensively used in the manufacturing and engineering sectors to create flat-bottomed holes that allow screw heads and bolt tops to sit flush with the surface of the material. Typically made from high-speed steel, cobalt steel, or carbide, these tools are crucial for achieving clean, professional finishes in a variety of materials, including metals, plastics, and wood. They are available in several types, such as interchangeable, fixed, and taper shank designs, each suited to specific tasks and materials.

Working Principle of Counterbores

• Creates flat-bottomed holes for hardware to sit flush with the material surface
• Enhances the finish of projects by hiding screw and bolt heads

Available Types Include

• Fixed counterbores for specific hole sizes
• Interchangeable counterbores with adjustable cutting diameters
• Taper shank counterbores for use in drill presses and milling machines
