M.a. Ford. 61012504 Countersink 100 Degree 1 Flute Hss

Product Description

The M.A. FORD. 61012504 is a single-flute, high-speed steel countersink designed for chamfering, countersinking, and deburring operations in metalworking and fabrication applications. It features a 100-degree included angle with a 1/8-inch shank diameter and an overall length of 1.5 inches. The straight-cylindrical shank seats securely in standard collets and drill chucks. The bright, uncoated finish is suitable for general-purpose cutting across a broad range of workpiece materials. Right-hand cutting direction is standard for conventional drill press and CNC spindle rotation. Licensed machinists, tool-and-die workers, and maintenance technicians are the primary users of this tool.

This countersink is suited for light-duty countersinking and deburring tasks in job shop, maintenance, and production environments. Its compact 1/8-inch shank and 1.5-inch overall length make it appropriate for tight-clearance work and small-diameter hole preparation. It is effective on a wide range of materials including mild steel, alloy steel, stainless steel, cast iron, high-tensile steel, high-nickel steel, Monel, aluminum, brass, magnesium, magnesium alloy, and plastic.

Installation Notes

Installation and use of this countersink should be performed by qualified machinists or metalworking professionals familiar with rotating cutting tools. Secure the shank fully in a collet or drill chuck before operation and verify runout is within acceptable limits. Always power down and lock out the machine spindle before changing or inspecting tooling. Use appropriate cutting fluid or lubricant for the workpiece material to extend tool life and improve finish quality.
