M.a. Ford 79B075002 Countersink 82 Deg 6 Flute Hss 3/4 in

Product Description

The M.A. FORD 79B075002 is a 6-flute, single-end countersink designed for precision chamfering and countersinking in metalworking and fabrication applications. Built from high-speed steel (HSS), it delivers consistent cutting performance across a wide range of materials. The tool features an 82-degree included angle, a maximum cutting diameter of 0.75 inches, a 0.5-inch straight-cylindrical shank, and an overall length of 2.75 inches. The right-hand cutting direction suits standard drill press, CNC, or handheld power tool setups. Machinists, tool-and-die makers, and metalworking tradespeople install this tool when a clean, accurate countersink seat is required for fastener flush-mounting.

This countersink is suited for both production and maintenance applications where consistent chamfer geometry is critical. The 82-degree angle is standard for flathead screws commonly used in aerospace and sheet metal assemblies. Compatible material applications include alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel. Its versatility makes it a practical tool for general machine shops, fabrication facilities, and MRO environments handling varied workpiece materials.

Key Features

• 82-degree included angle for standard flathead screw countersink geometry
• 6-flute design promotes smooth cutting action and reduced chatter
• High-speed steel construction provides durability across a broad material range
• 0.5-inch straight-cylindrical shank for compatibility with standard tool holders and chucks
• Right-hand cutting direction suits conventional drill press and CNC setups
• Single-end configuration for straightforward tool changes

Compatibility

Designed as a direct-fit countersink tool for use in standard 0.5-inch straight-shank tool holders, collet chucks, and drill press quills. 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.

Installation Notes

This tool is installed by machinists and metalworking tradespeople using standard drill press, milling machine, or handheld power tool setups. Secure the straight-cylindrical shank firmly in a properly sized collet or chuck before operation. Always power down and de-energize the machine spindle before tool changes. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain chamfer quality.
