Hertel 334-006080 Carbide Countersink 1/2 in 4 Flute

Product Description

The HERTEL 334-006080 is a solid carbide countersink designed for producing conical seat holes in metal and other hard materials. With a 1/2 inch head diameter and a 100-degree included angle, it creates the correct seating geometry for flat-head fasteners in a wide range of machining applications. The straight-cylindrical shank measures 3/8 inch in diameter, allowing it to seat securely in standard drill chucks or collet holders. Four flutes provide balanced cutting action and efficient chip evacuation, contributing to consistent finish quality across repeated operations. This tool is intended for use by machinists, tool-and-die professionals, and precision fabricators working on CNC or manual machine setups.

This countersink is suited for production and job-shop environments where accurate fastener seating is required in steel, aluminum, cast iron, and similar materials. The 100-degree included angle is a commonly specified geometry for aerospace and industrial fastener standards. It fits standard 3/8 inch toolholding on milling machines, drill presses, and lathes. Single-piece packaging makes it a straightforward direct replacement or addition to an existing tooling setup.

Key Features

• Solid carbide construction for extended tool life in hard or abrasive materials
• 1/2 inch head diameter accommodates a range of fastener seating requirements
• 100-degree included angle matches common industrial and aerospace fastener specs
• 4-flute design promotes smooth cutting action and efficient chip removal
• 3/8 inch straight-cylindrical shank for compatibility with standard chucks and collets

Compatibility

Designed as a direct-fit countersink for use in standard 3/8 inch drill chucks, collet holders, and toolholding systems on CNC mills, manual mills, and drill presses requiring a 1/2 inch head diameter, 100-degree countersink geometry.

Installation Notes

Installation is performed by machinists or tooling technicians familiar with rotary cutting tools. Secure the shank fully in the chuck or collet before operation and verify runout before cutting. Always power down and lock out the spindle before changing tooling. Follow shop-standard feeds and speeds for carbide tooling in the workpiece material being machined.
