Solid Pilot Counterbore: 20 mm Dia, 13 mm Pilot, 3 Flutes MPN:10569

Solid pilot counterbores are specialized tools designed for machining through holes in metallic materials such as aluminum or steel. The diameter of the drill bit is reduced incrementally using a series of successively smaller drill bits, creating a threaded hole that extends into the workpiece while maintaining its outer diameter. Typical customers of solid pilot counterbores include automotive manufacturers, aerospace engineers, and precision machinery assemblers. The 20mm diameter, 13mm pilot size, and three flutes make it suitable for creating threads with a precise fit, allowing for strong fastening applications in the respective industries where these counterbores are employed.
