M.a. Ford. 92050001 Countersink 60 Degree 3 Flute Hss

Product Description

The M.A. FORD. 92050001 is a single-end, three-flute countersink designed for chamfering, countersinking, and deburring operations in a wide range of materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable performance in production and job-shop environments. The tool features a 60-degree included angle, a 1/2-inch head diameter, and a 1/4-inch straight cylindrical shank, with an overall length of 2 inches. No pilot is included. The bright finish suits general-purpose work where coating is not required. Machinists, tool-and-die technicians, and skilled tradespeople working with metalworking or fabrication equipment are the primary users.

This countersink is suited for use on drill presses, CNC machining centers, manual milling machines, and hand-held pneumatic or electric drills where a 1/4-inch shank capacity is available. It handles a broad range of materials including aluminum, brass, magnesium, magnesium alloy, high-nickel steel, Monel, and plastic. The 60-degree angle is commonly specified for aerospace and general metalworking fastener seat preparation. The compact 2-inch overall length makes it easy to use in tight clearance situations.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with rotating cutting tools. Always secure the workpiece and ensure the machine spindle is fully stopped before changing tooling. Use appropriate cutting fluid or lubricant for the material being machined. Follow shop safety protocols and machine manufacturer guidelines for speed and feed selection when operating this tool.
