Hertel 334-307080 Carbide Countersink 5/8 in 4 Flute

Product Description

The HERTEL 334-307080 is a solid carbide countersink designed for creating clean, accurate chamfered holes in metal and other hard materials. With a 5/8-inch head diameter and a 100-degree included angle, it produces consistent conical seats for flat-head fasteners and deburring operations. The straight-cylindrical shank measures 5/8 inch in diameter, making it compatible with standard drill chucks and collet holders. Four flutes provide balanced cutting action and efficient chip evacuation. This tool is installed and operated by machinists, tool-and-die workers, and maintenance technicians working on precision fabrication and assembly tasks.

The 334-307080 countersink suits bench-drill, drill-press, and CNC machining center applications where controlled countersinking depth and surface finish are required. The 100-degree included angle is a common specification for aerospace and general metalworking fastener seat preparation. The carbide construction supports use in harder workpiece materials where high-speed steel tooling would wear prematurely. Single-piece packaging makes it straightforward to add to a tool crib or individual toolbox without sorting through multi-unit quantities.

Key Features

• 5/8-inch head diameter for standard countersink profiles
• 100-degree included angle suits flat-head fastener seating and chamfering
• Four flutes for balanced cutting and efficient chip removal
• Solid carbide construction for extended tool life in hard materials
• 5/8-inch straight-cylindrical shank fits standard chucks and collet holders

Compatibility

Designed as an OEM-style cutting tool replacement for drill press, manual, and CNC machining setups requiring a 5/8-inch straight-shank countersink with a 100-degree included angle.

Installation Notes

Installation is performed by machinists or qualified maintenance technicians. Secure the straight-cylindrical shank firmly in a drill chuck or collet before operation and confirm runout is within acceptable limits for the application. Always power down and de-energize the machine spindle before changing or adjusting tooling. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life and surface finish quality.
