Hertel 334-010080 Countersink 1 in 100 Deg 4 Flute Carbide

Product Description

The HERTEL 334-010080 is a solid carbide countersink designed for precision chamfering and countersinking operations in metal, composites, and similar materials. It features a 1 inch head diameter, a 100 degree included angle, and 4 flutes for smooth, chatter-resistant cutting. The straight cylindrical shank measures 0.5 inches in diameter, allowing it to seat securely in standard drill chucks and collet holders. This tool is built for production and maintenance environments where accurate countersink geometry is required on fastener holes. Machinists, toolmakers, and maintenance mechanics are the primary users.

This countersink is suited for use on CNC machining centers, drill presses, and manual mills in both job shop and production settings. The 100 degree included angle accommodates fastener head profiles commonly found in aerospace and industrial applications. The 4-flute design provides a cleaner finish than single-flute tools and supports consistent cutting at moderate feed rates. It is appropriate for use in light to medium-duty countersinking tasks on steel, aluminum, and similar workpiece materials where carbide tool life and finish quality are priorities.

Key Features

• 1 inch head diameter for coverage of standard and large fastener hole chamfers
• 100 degree included angle suited to aerospace and industrial fastener specifications
• 4-flute geometry promotes smooth cutting action and improved surface finish
• Solid carbide construction provides hardness and wear resistance for longer tool life
• Straight cylindrical shank at 0.5 inches diameter for compatibility with standard chucks and collets

Compatibility

Designed as a direct-fit countersink for use in standard drill chucks and collet holders accepting a 0.5 inch straight cylindrical shank, suitable for CNC and manual machine tool setups requiring a 100 degree included angle carbide countersink.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the chuck or collet. Confirm shank seating depth and runout with a dial indicator before beginning cuts. Always follow applicable shop safety standards and machine manufacturer guidelines for tool speeds and feeds when using carbide cutting tools.
