Hertel 18124 Countersink 2 in 60 Degree 6 Flute Hss

Product Description

The HERTEL 18124 is a multi-flute countersink designed for creating precise conical seat profiles in metal workpieces. Built from high speed steel, this tool delivers consistent cutting performance in production and job-shop environments where accuracy and tool life matter. The 2-inch head diameter and 60-degree included angle make it well suited for chamfering, deburring, and countersinking operations that require a wide, shallow cone profile. With 6 flutes, it produces a smooth finish while reducing chatter during the cut. The straight-cylindrical shank measures 1 inch in diameter, compatible with standard machine tool holders and drill press chucks.

This countersink is used in metalworking applications across machine shops, fabrication facilities, and maintenance departments. It is typically run in drill presses, milling machines, or CNC machining centers fitted with appropriate 1-inch straight-shank holders. The 60-degree angle is commonly specified for aerospace and general-purpose fastener seat preparation. Machinists and tooling specialists are the primary users. It is sold individually with a minimum order quantity of 1 unit.

Installation Notes

Installation and use should be performed by qualified machinists or tooling personnel familiar with metal cutting operations. Power down and lock out the spindle before inserting or removing the tool from the holder. Secure the shank fully in the collet or chuck to the minimum recommended grip depth before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain finish quality.
