Hertel 333-009060 Carbide Countersink 7/8 in 82 Deg 3 Flute

Product Description

The HERTEL 333-009060 is a solid carbide countersink designed for precision chamfering and seat preparation in metal, composite, and hard material applications. It features a 7/8 inch head diameter with an 82-degree included angle, making it suited for flat-head fastener seating conforming to standard aerospace and industrial hardware profiles. The 3-flute geometry provides a balance of chip evacuation and surface finish quality. The bright, uncoated carbide construction offers rigidity and wear resistance for demanding drilling environments. This tool is installed and operated by machinists and metalworking professionals using standard milling machines, drill presses, or hand drills with appropriate speed control.

This countersink is used in production and maintenance machining environments where consistent, accurate countersunk holes are required for flat-head screws and rivets. The 1/2 inch straight-cylindrical shank fits standard collets and drill chucks. The single-end, no-pilot configuration allows the operator to guide the tool directly into a pre-drilled hole. It is appropriate for applications across general manufacturing, aerospace component work, and structural fabrication where 82-degree flat-head hardware is specified.

Key Features

• 7/8 inch head diameter with 82-degree included angle for standard flat-head fastener seating
• 3-flute design balances chip removal with smooth surface finish
• Solid carbide construction for rigidity and extended tool life in hard materials
• 1/2 inch straight-cylindrical shank fits standard collets and drill chucks
• Bright uncoated finish — no coating buildup concerns in sensitive alloy applications
• Single-end, no-pilot design for direct placement into pre-drilled holes

Compatibility

Designed as an OEM-style replacement or standard tooling selection for applications requiring an 82-degree countersink with a 1/2 inch straight shank and 7/8 inch head diameter in production or maintenance machining setups.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with cutting tool setup and spindle speed selection for carbide tooling. Secure the shank fully in the collet or chuck before operation and verify runout before use. Power down and de-energize the machine spindle before changing or adjusting the tool. Follow applicable shop safety standards and manufacturer speed-and-feed recommendations for carbide countersinks in the workpiece material being cut.
