Hertel 334-206100 Carbide Countersink 1/2 in 120 Deg 4 Flutes

Product Description

The HERTEL 334-206100 is a solid carbide countersink designed for precise chamfering and seat-forming operations in metalworking and fabrication applications. It features a 0.5 inch head diameter, a 120-degree included angle, and 4 flutes for smooth chip evacuation and consistent surface finish. The straight-cylindrical shank measures 0.5 inches in diameter, providing secure chuck or collet retention in standard drilling equipment. This tool is suited for machinists, tool-and-die tradespeople, and precision fabricators working with ferrous and non-ferrous materials.

This countersink is used in CNC machining centers, manual mills, and drill presses where controlled chamfer depth and angle accuracy are required. The 120-degree included angle is common for deburring, chamfering fastener holes, and preparing countersunk screw seats in sheet metal, plate, and structural components. The carbide construction supports higher feed rates and longer tool life compared to high-speed steel alternatives, making it a practical choice for production environments and job shop work.

Key Features

• 0.5 inch head diameter for standard chamfering and countersinking operations
• 120-degree included angle suits common fastener seat and deburring requirements
• 4-flute geometry promotes smooth cutting action and efficient chip clearance
• Solid carbide construction extends tool life in high-cycle or production use
• Straight-cylindrical 0.5 inch shank fits standard drill chucks and collet holders

Compatibility

Designed as a direct-fit replacement-style countersink for use with standard 0.5 inch straight-shank toolholders, collet chucks, and drill press spindles commonly found in machine shop and fabrication environments.

Installation Notes

Installation should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools. Ensure the machine spindle is fully powered down and locked out before inserting or removing the tool from the holder. Confirm the shank is fully seated and the collet or chuck is torqued to the toolholder manufacturer specification before operation. Always verify spindle speed and feed rate against the toolholder and workpiece material requirements before engaging the cut.
