M.a. Ford 79200006 Countersink 120 Degree 6 Flute Hss

Product Description

The M.A. FORD 79200006 is a single-end, 6-flute countersink designed for chamfering, countersinking, and deburring operations across a wide range of materials. Built from high-speed steel with a bright/uncoated finish, it features a 120-degree included angle and a 2-inch head diameter. The straight-cylindrical shank measures 3/4 inch in diameter, and the tool runs 3.75 inches overall length. It cuts in a right-hand direction and is sized for use in production and maintenance machining environments. Machinists, tool-and-die professionals, and fabrication shops are the primary users of this tool.

This countersink is suited for applications on alloy steel, mild steel, stainless steel, cast iron, high-tensile steel, high-nickel steel, Monel, aluminum, brass, magnesium, magnesium alloy, and plastic. The 120-degree included angle makes it appropriate for large-angle chamfer work and countersinking fastener seats where a wide, shallow profile is required. It is used in both manual and CNC machine tool setups for general-purpose material removal and hole finishing.

Installation Notes

This tool is installed and operated by machinists and fabricators using drill presses, milling machines, or CNC machining centers with a compatible 3/4-inch collet or chuck. Ensure the machine spindle is fully stopped and the tool is firmly seated before beginning any cut. Use appropriate cutting fluid or lubricant when working with ferrous or hard alloy materials to extend tool life. Inspect flute edges for wear or chipping before each use.
