Hertel 334-208050 Carbide Countersink 3/4 in 60 Degree 4 Flute

Product Description

The HERTEL 334-208050 is a solid carbide countersink designed for precise chamfering and countersinking operations in metalworking and machining applications. With a 3/4-inch head diameter, a 60-degree included angle, and 4 flutes, this tool delivers clean, accurate seat geometry for fastener holes. The straight cylindrical shank measures 3/4 inch in diameter, providing secure clamping in standard drill chucks or collet holders. It is suited for use on CNC machining centers, drill presses, and manual mills where consistent countersink depth and finish quality are required.

This countersink is used in production and job-shop machining environments where ferrous and non-ferrous materials require chamfered fastener seats. The 60-degree included angle accommodates metric-style fastener applications. The 4-flute geometry balances cutting speed with surface finish, making this tool appropriate for both light production runs and precision one-off work. It is typically installed and operated by machinists and tool-and-die professionals in manufacturing, maintenance, and fabrication settings.

Key Features

• 3/4-inch head diameter for larger fastener seat preparation
• 60-degree included angle suited for metric-style countersunk fasteners
• 4-flute design balances material removal rate with finish quality
• Solid carbide construction for hardness and wear resistance
• Straight cylindrical shank for compatibility with standard chucks and collet systems

Compatibility

Designed as an OEM-style solid carbide countersink for use in standard 3/4-inch straight-shank toolholders, drill chucks, and collet systems on CNC and manual machine tools.

Installation Notes

Installation and use should be performed by qualified machinists familiar with cutting tool setup and speeds-and-feeds selection. Secure the shank fully in the toolholder before operation and verify runout before cutting. Always power down and lock out the machine spindle before changing or adjusting tooling. Do not exceed the recommended surface footage for carbide tooling in the material being machined.
