M.a. Ford 79T100002 Countersink 82 Degree 6 Flute Hss Tin

Product Description

The M.A. FORD 79T100002 is a single-end, 6-flute countersink designed for producing clean, accurate 82-degree countersunk holes in a wide range of materials. Manufactured from high-speed steel with a TiN (titanium nitride) coating, this tool delivers extended wear life and reduced friction during cutting operations. The straight-cylindrical shank measures 0.5 inches in diameter, and the overall length is 2.75 inches. With a minimum cutting diameter of 0.25 inches and a maximum cutting diameter of 1 inch, it covers a broad range of fastener head sizes. Machinists and tool-and-die tradespeople install this countersink in manual or CNC drilling setups for precision deburring and seat preparation work.

This countersink is suited for use in general machining, fabrication, and production environments. It handles a wide variety of workpiece materials, including alloy steel, mild steel, stainless steel, high-tensile steel, high-nickel steel, cast iron, aluminum, brass, Monel, magnesium, magnesium alloy, and plastic. The 82-degree included angle matches the standard American fastener head geometry, making it appropriate for flat-head screw seating in both ferrous and non-ferrous applications across light manufacturing, maintenance, and repair operations.

Key Features

• 82-degree included angle matches standard American flat-head fastener geometry
• 6-flute design provides smooth cutting action and improved surface finish
• TiN coating extends tool life and reduces heat buildup at the cutting edge
• High-speed steel construction supports use across a broad range of workpiece materials
• Straight-cylindrical shank for straightforward chucking in standard drill chucks or collets
• Single-end configuration with right-hand cutting direction

Compatibility

Designed as a replacement-style countersink for standard 82-degree flat-head fastener applications. Compatible with materials including alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel, as specified by the manufacturer.

Installation Notes

Installation is performed by machinists or tool operators. Secure the straight shank in a compatible drill chuck or collet before operation, ensuring the workpiece is firmly fixtured. Set spindle speed according to the workpiece material and cutting diameter before engaging the tool. Inspect the cutting edges and TiN coating for wear before each use, and do not force the tool through hardened materials beyond its rated material application range.
