M.a. Ford. 79018702 Countersink 82 Deg 6 Flute Hss

Product Description

The M.A. FORD. 79018702 is a single-end, 6-flute countersink machined from high-speed steel and designed for right-hand cutting operations. It carries an 82-degree included angle, making it suited for standard fastener seat preparation across a wide range of material types. The straight-cylindrical shank measures 3/16 inches in diameter, and the tool runs 2 inches in overall length. The bright, uncoated finish is appropriate for general-purpose use. Machinists, tool-and-die shops, and maintenance technicians use this countersink for chamfering, countersinking, and deburring in production and repair environments.

This countersink is built for use across a broad material application range. It cuts cleanly in alloy steel, mild steel, stainless steel, high-tensile steel, high-nickel steel, Monel, cast iron, aluminum, brass, magnesium, magnesium alloy, and plastic. The 82-degree angle matches the standard seating angle for flat-head fasteners used in aerospace and general metalworking applications. It fits straight-shank tool holders and collet chucks sized for 3/16-inch shanks and performs in both manual and CNC machine tool setups.

Key Features

Compatibility

Designed for use with straight-shank tool holders and collets sized for 3/16-inch shank diameters. Suitable for chamfering, countersinking, and deburring operations on alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel.

Installation Notes

Install in a properly sized collet or drill chuck rated for 3/16-inch straight-cylindrical shanks. Secure workpieces before beginning any cutting operation and confirm spindle direction is set to right-hand rotation before engaging the tool. Use appropriate cutting fluid or lubricant for the workpiece material to extend tool life and improve finish quality. Follow shop safety procedures and applicable machine guarding standards when operating rotary cutting tools.
