Hertel 336-007080 Countersink 5/8 in 6 Flute Carbide

Product Description

The HERTEL 336-007080 is a solid carbide countersink designed for precision chamfering and deburring of drilled holes in metalworking and fabrication applications. It features a 5/8 inch head diameter, a 100-degree included angle, and 6 flutes for smooth, chatter-resistant cutting action. The straight-cylindrical shank measures 3/8 inch in diameter, making it compatible with standard drill chucks and collet holders. This countersink is built for machinists and tool-and-die professionals who require consistent geometry and clean finishes in production or job-shop environments.

This countersink is suited for use on machining centers, drill presses, and hand-held power tools where countersinking or chamfering operations are performed on ferrous and non-ferrous materials. The 100-degree included angle accommodates fastener seating requirements that fall outside the common 82-degree and 90-degree standards. Typical applications include aerospace, automotive, and general manufacturing where precise countersink geometry is critical to fastener flush-fit or part finish specifications.

Key Features

• 5/8 inch head diameter provides adequate countersink coverage for medium-range hole sizes
• 100-degree included angle meets fastener seating specs where standard angles do not apply
• 6 flutes deliver smooth cutting action and reduce chatter during operation
• Solid carbide construction offers hardness and wear resistance for extended tool life
• 3/8 inch straight-cylindrical shank fits standard chucks and collet holders

Compatibility

Designed as a standard straight-shank countersink for use in drill chucks and collet-style toolholders accepting a 3/8 inch shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or skilled tradespeople familiar with rotating cutting tools. Secure the straight shank firmly in a drill chuck or collet holder before operation, and verify runout is within acceptable tolerance for the application. Always use appropriate cutting fluid or coolant for the workpiece material to extend tool life and maintain surface finish quality. Inspect the cutting edges before each use and remove the tool from service if chipping or wear is observed.
