M.a. Ford 79B050002 Countersink 82 Degree 6 Flute Hss

Product Description

The M.A. FORD 79B050002 is a single-end, 6-flute countersink designed for producing clean, accurate 82-degree countersunk holes in a wide range of materials. Machined from high-speed steel, this tool features a straight-cylindrical shank and right-hand cutting direction, making it a standard fit for drill press, CNC, and hand-held applications. The 82-degree included angle is the industry standard for flat-head fastener seating in metalwork and fabrication. With a 0.5 inch maximum cutting diameter and an overall length of 2 inches, this countersink is well-suited for production and maintenance work where consistent fastener prep is required.

This countersink is used in metal fabrication shops, machine shops, and general manufacturing environments. It handles a broad spectrum of materials, including mild steel, alloy steel, stainless steel, cast iron, aluminum, brass, magnesium, high-tensile steel, high-nickel steel, Monel, and plastic. It is appropriate for both production runs and one-off part preparation. Licensed machinists, tool-and-die technicians, and skilled maintenance trades are the typical users.

Key Features

• 82-degree included angle matches the standard for flat-head and oval-head fastener seating
• 6-flute geometry provides smoother surface finish and reduced chatter compared to fewer-flute designs
• High-speed steel construction offers good toughness across a wide material range
• Straight-cylindrical shank fits standard drill chucks and collet holders without adapters
• Single-end design for straightforward setup and replacement
• Right-hand cutting direction compatible with standard drill press and CNC spindle rotation

Compatibility

Suitable for countersinking operations in alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel. Fits any drill chuck or collet holder accepting a 3/8 inch straight-cylindrical shank.

Installation Notes

Install in a drill press, lathe, or CNC machine using a drill chuck or collet sized for a 3/8 inch shank. Ensure the spindle is at a complete stop and power is disconnected before changing tooling. Use appropriate cutting fluid for ferrous and high-nickel materials to extend tool life and improve finish quality. Follow shop safety standards and any applicable OSHA guidelines when operating rotary cutting tools.
