Hertel 334-301050 Countersink 1/8 in 60 Degree 4 Flute Carbide

Product Description

The HERTEL 334-301050 is a solid carbide countersink designed for precision chamfering and deburring of drilled holes in metalworking and fabrication applications. It features a 1/8 inch head diameter with a 60-degree included angle, making it suited for light countersinking work where accuracy and clean entry geometry matter. The 4-flute design provides smooth cutting action and improved chip evacuation compared to single-flute styles. The straight cylindrical shank measures 1/8 inch in diameter for direct chuck mounting. Machinists, tool and die makers, and CNC operators rely on this type of tool for consistent, repeatable results on close-tolerance work.

This countersink is intended for use in machine shops, maintenance facilities, and production environments where small-diameter countersinking is required. It is well-suited for creating countersunk seats for flat-head fasteners, deburring drilled holes, or chamfering edges on ferrous and non-ferrous materials. The carbide construction handles harder workpiece materials where high-speed steel tools wear prematurely. It is compatible with standard drill presses, CNC machining centers, and manual mills equipped with an appropriate collet or drill chuck accepting a 1/8 inch straight shank.

Key Features

• 1/8 inch head diameter for small-diameter countersinking applications
• 60-degree included angle for standard flat-head fastener seat geometry
• 4-flute design promotes smooth cutting and efficient chip removal
• Solid carbide construction provides superior hardness and wear resistance over HSS
• Straight cylindrical 1/8 inch shank for direct chuck or collet mounting

Compatibility

Designed for use in drill presses, CNC machining centers, and milling machines equipped with a collet or chuck accepting a 1/8 inch straight cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with cutting tool safety. Secure the shank firmly in a collet or drill chuck rated for the intended spindle speed before operation. Carbide tooling is brittle and should not be dropped or subjected to heavy lateral loads. Always follow applicable machine guarding requirements and wear appropriate eye protection during use.
