Hertel 333-007060 Carbide Countersink 5/8 in 82 Degree 3 Flute

Product Description

The HERTEL 333-007060 is a solid carbide countersink designed for precision countersinking operations in metalworking and fabrication applications. It features an 82-degree included angle and a 5/8-inch head diameter, making it well suited for producing flat-head fastener recesses to standard aerospace and commercial specifications. The 3/8-inch straight cylindrical shank provides consistent tool holding in standard drill chucks and collet holders. With 3 flutes and a bright uncoated finish, this countersink delivers clean, accurate seat geometry in a range of workpiece materials. Licensed machinists, toolmakers, and metalworking professionals are the primary users of this tool.

This countersink is used in machine shops, production environments, and maintenance facilities where countersunk holes are required for flat-head screws, rivets, or similar fasteners. It is suited for use in CNC machining centers, drill presses, and manual milling machines. The 82-degree included angle matches the standard for flat-head machine screws common in aerospace, industrial, and general metalworking assemblies. It operates with a right-hand cutting direction and does not include a pilot, allowing flexible use across hole sizes within its head diameter range.
