M.a. Ford. 79T100001 Countersink 60 Degree 6 Flute Hss Tin

Product Description

The M.A. FORD. 79T100001 is a single-end, 6-flute countersink designed for precision chamfering and countersinking operations in metal fabrication and machining environments. Built from high-speed steel with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction across a wide range of workpiece materials. The 60-degree included angle is suited for standard fastener seat preparation. The straight-cylindrical shank measures 0.5 inches in diameter, and the overall length is 2.75 inches. This tool is typically installed by machinists, tool-and-die workers, and maintenance technicians operating drill presses, CNC machines, or hand drills.

This countersink is appropriate for use on alloy steel, mild steel, stainless steel, cast iron, aluminum, brass, magnesium, magnesium alloy, high-tensile steel, high-nickel steel, Monel, and plastic workpieces. The cutting range spans from 0.25 inches minimum to 1 inch maximum cutting diameter, making it suitable for a broad set of countersink diameters in both production and maintenance settings. It is a right-hand cutting tool and is sold individually.

Key Features

• 60-degree included angle for standard fastener seat geometry
• 6-flute design for smooth, chatter-resistant cutting action
• TiN coating extends tool life and reduces built-up edge on difficult materials
• High-speed steel construction handles a wide range of metals and plastics
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Cutting diameter range of 0.25 inches to 1 inch covers common fastener sizes

Compatibility

Designed for use on alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel. Compatible with drill presses, CNC machining centers, and hand drills accepting a 0.5-inch straight-cylindrical shank.

Installation Notes

This tool is installed by machinists or maintenance technicians. Secure the straight-cylindrical shank firmly in a properly sized drill chuck or collet before operation. Use appropriate cutting fluid or lubricant when working with steel, stainless, or high-nickel alloys to preserve cutting edge life. Always wear appropriate eye protection and follow shop safety protocols when operating rotary cutting tools.
