M.a. Ford. 67112502 Countersink 82 Degree Hss

Product Description

The M.A. FORD. 67112502 is a single-end, zero-flute countersink designed for chamfering, countersinking, and deburring operations across a wide range of materials. Built from high-speed steel with a bright uncoated finish, it features an 82-degree included angle and a 1-1/8 inch head diameter with a maximum cutting diameter of 1.03 inches. The straight cylindrical shank measures 1/2 inch in diameter, and the tool runs 2-7/8 inches in overall length. It is sized for general machine shop and fabrication use and does not include a pilot. Right-hand cutting direction suits standard spindle rotation on most drill presses and mills.

This countersink is suited for production and maintenance machining environments where consistent chamfer angles are required. The zero-flute design reduces chatter and produces a smooth finish on softer and harder materials alike. It is used by machinists, tool and die technicians, and fabricators working with alloy steel, mild steel, stainless steel, cast iron, aluminum, brass, magnesium, magnesium alloy, high-tensile steel, high-nickel steel, Monel, and plastic substrates.

Key Features

Compatibility

Designed as an OEM-style straight-shank countersink compatible with 1/2 inch collets, keyless chucks, and drill press spindles accepting cylindrical straight shanks.

Installation Notes

Installation and use should be performed by qualified machinists or fabrication technicians. Secure the shank fully in the collet or chuck before operation, and confirm the workpiece is clamped or fixtured to prevent movement. Apply an appropriate cutting fluid for the workpiece material, especially on ferrous metals and stainless steel. Power down and de-energize the machine spindle completely before tool changes or adjustments.
