Counterbores & Port Tools

0 products

Counterbores, also known as spotfacers, are designed to create a flat-bottomed recess at the top of a pre-existing hole, enabling bolts, nuts, or other components to sit flush or be concealed beneath the surface. Available with either fixed or interchangeable pilots, these tools accommodate various diameters for enhanced versatility. Port tools are specialized for shaping holes to ensure a perfect fit for port installations. For optimal performance, the pilot or tip of the counterbore or port tool must match the hole's diameter, ensuring precise centering during operation. Ideal for metalworking applications, these tools are essential for achieving professional-grade finishes.
