Hertel 334-303050 Carbide Countersink 1/4 in 60 Degree 4 Flute

Product Description

The HERTEL 334-303050 is a solid carbide countersink designed for precision chamfering and countersinking in metalworking, machining, and fabrication applications. It features a 1/4 inch head diameter, a 60-degree included angle, and 4 flutes for efficient chip evacuation and a clean finish. The straight cylindrical shank measures 1/4 inch in diameter, providing positive seating in standard drill chucks and collet holders. This countersink is suited for use in CNC machining centers, drill presses, and hand-held drill applications where consistent angular seat geometry is required. Machinists and tool-and-die technicians rely on carbide construction for extended tool life in harder work materials.

This countersink is used across general metalworking, aerospace fabrication, and precision machining shops. The 60-degree included angle is commonly specified for fastener seat preparation in aluminum, steel, and similar metals. The 4-flute configuration provides a balance of cutting speed and surface finish quality. It is appropriate for both production runs and prototype work where repeatable countersink geometry is critical.

Key Features

• 1/4 inch head diameter for small-diameter countersink applications
• 60-degree included angle matches standard fastener seat geometry
• 4-flute design promotes efficient chip removal and surface finish quality
• Solid carbide construction extends tool life in harder and abrasive materials
• Straight cylindrical shank seats securely in standard chucks and collets

Compatibility

Designed as an OEM-style replacement or direct-use countersink for machines accepting a 1/4 inch straight cylindrical shank tooling, including standard drill chucks and collet-style tool holders used in CNC and manual machining equipment.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools. Ensure the machine spindle is fully stopped and the tool holder is de-energized before inserting or removing the countersink. Confirm proper chuck or collet clamping torque per the tool holder manufacturer specifications before operation. Eye protection and appropriate guarding should be in place at all times during use.
