Hertel 334-008060 Countersink 3/4 in 82 Deg 4 Flute Carbide

Product Description

The HERTEL 334-008060 is a solid carbide countersink designed for precision chamfering and deburring of drilled holes in metalworking and fabrication applications. The tool features a 3/4 inch head diameter and an 82-degree included angle, making it suited for seating flat-head fasteners and preparing hole entries to close tolerances. The 1/2 inch straight-cylindrical shank mounts directly into standard drill press, milling machine, or CNC collet and chuck setups. With 4 flutes, it delivers smooth cutting action and good chip evacuation. Carbide construction provides durability and cutting performance on a range of ferrous and non-ferrous materials.

This countersink is appropriate for job shop, production machining, and toolroom use wherever consistent chamfer geometry is required. It is commonly used by machinists and fabricators preparing holes for flat-head screws and bolts to an 82-degree seating angle. The straight-cylindrical shank allows direct chucking without adapters in most standard setups. It is sold individually and is suitable for both manual machine operation and light CNC work where a rigid, single-piece carbide tool is preferred over multi-piece or adjustable countersink assemblies.

Key Features

• 3/4 inch head diameter for chamfering holes suited to standard flat-head fastener sizes
• 82-degree included angle matches common flat-head screw seating geometry
• 4-flute design provides smooth cutting and efficient chip clearance
• Solid carbide construction for durability and performance on ferrous and non-ferrous materials
• 1/2 inch straight-cylindrical shank for direct mounting in collets, drill chucks, and milling setups

Compatibility

Designed as an OEM-style single-flute replacement or direct-use countersink compatible with any drill press, milling machine, or CNC spindle accepting a 1/2 inch straight-cylindrical shank. No specific model compatibility data was provided in the product input.

Installation Notes

Installation is performed by machinists and tool and die tradespeople using standard collet or drill chuck setups. Ensure the spindle and workpiece are fully secured before engaging the tool, and confirm the machine is powered off and de-energized before tool changes. Use appropriate cutting fluid or lubricant for the workpiece material to extend tool life and maintain finish quality. Verify shank runout is within acceptable tolerances before production use to avoid uneven chamfer geometry.
