M.a. Ford. 61T050006 Countersink 120 Degree 1 Flute Hss Tin

Product Description

The M.A. FORD. 61T050006 is a single-flute, high-speed steel countersink with a 120-degree included angle and a titanium nitride (TiN) coating. It is designed to produce clean, accurate countersunk holes in a wide range of materials encountered in machining and fabrication work. The straight-cylindrical shank measures 0.25 inches in diameter, the maximum cutting diameter is 0.5 inches, and the overall length is 2 inches. The TiN finish increases surface hardness and reduces friction, extending tool life in production environments. Machinists, toolmakers, and precision fabricators are the primary users of this tooling.

This countersink is suited for use in manual machine tools, drill presses, CNC machining centers, and hand-held power tools where a consistent 120-degree countersink profile is required. The single-flute design limits chatter and produces a smooth finish in both ferrous and non-ferrous materials. It is appropriate for light-duty production runs and precision one-off applications in job shops, maintenance facilities, and manufacturing environments. The right-hand cutting direction is standard for conventional machine tool spindle rotation.

Key Features

• 120-degree included angle for standard countersink profiles
• Single-flute geometry reduces chatter and improves surface finish
• TiN coating increases hardness and extends tool life
• High-speed steel construction handles a broad range of workpiece materials
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Right-hand cutting direction compatible with conventional spindle rotation

Compatibility

Suitable for countersinking alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel workpieces. Fits any drill chuck or collet accepting a 0.25-inch straight-cylindrical shank.

Installation Notes

Install into a drill chuck or collet holder rated for the shank diameter before starting the machine. Secure the workpiece firmly to prevent movement during countersinking. Always bring the spindle to a stop completely before changing or adjusting tooling. Use appropriate cutting fluid or lubrication when working with ferrous metals to preserve coating life and edge integrity.
