Hertel 334-006070 Carbide Countersink 1/2 in 90 Deg 4 Flute

Product Description

The HERTEL 334-006070 is a solid carbide countersink designed for producing clean, accurate countersunk holes in metal and hard materials. Built with a 4-flute geometry and a 90-degree included angle, this tool delivers smooth cutting action and consistent finish quality in production and maintenance drilling applications. The 1/2-inch head diameter and 3/8-inch straight cylindrical shank make it compatible with standard drill chucks and collet holders. Carbide construction provides the hardness and wear resistance needed for repetitive use in ferrous and non-ferrous metals. Machinists, tool-and-die technicians, and maintenance professionals rely on this style of countersink for deburring, chamfering, and fastener seat preparation.

This countersink is suited for machine shop, fabrication, and maintenance environments where precision chamfering and countersinking are routine operations. The 90-degree included angle matches the most common fastener seat geometry, making it appropriate for preparing holes for flat-head screws and bolts in steel, aluminum, and similar materials. The straight cylindrical shank seats directly in drill press chucks, milling machine collets, and CNC tool holders without requiring an adapter.

Key Features

• Carbide construction for extended tool life in hard and abrasive materials
• 90-degree included angle matches standard flat-head fastener seat geometry
• 4-flute design for smooth cutting action and consistent surface finish
• 1/2-inch head diameter suitable for common fastener sizes
• 3/8-inch straight cylindrical shank fits standard drill chucks and collet holders

Compatibility

Designed as an OEM-style replacement or direct-use countersink for machine tools accepting a 3/8-inch straight cylindrical shank, including drill presses, milling machines, and CNC machining centers.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with rotary cutting tool safety. Ensure the shank is fully seated and securely clamped in the chuck or collet before operation. Run at speeds appropriate for carbide tooling and the workpiece material to avoid chipping the cutting edges. Inspect the tool for chipping or wear before each use and do not run a damaged countersink.
