M.a. Ford 92100002 Countersink 82 Degree 3 Flute Hss

Product Description

The M.A. FORD 92100002 is a single-end, three-flute countersink designed for chamfering, countersinking, and deburring operations in metalworking and fabrication environments. Built from high-speed steel with a bright uncoated finish, it features an 82-degree included angle and a 0.500-inch straight cylindrical shank. The 1-inch head diameter and 3.25-inch overall length make it well suited for standard-depth countersink work on flat and contoured workpieces. Machinists and tool-and-die professionals install this tool in drill presses, milling machines, and hand-held power tools where consistent chamfer geometry and clean entry angles are required.

This countersink is intended for use on softer and medium-hardness materials including aluminum, brass, magnesium, magnesium alloy, Monel, high-nickel steel, and plastic. The right-hand cutting direction and three-flute geometry provide smooth, chatter-resistant cutting action across these material groups. It is a practical choice for production shops, maintenance facilities, and job-site fabrication tasks where a reliable general-purpose countersink is needed without pilot guidance.

Key Features

• 82-degree included angle for standard aerospace and general-purpose countersink profiles
• Three-flute design reduces chatter and improves surface finish in softer metals and plastics
• High-speed steel construction provides good wear resistance across a broad material range
• Bright uncoated finish suitable for aluminum, brass, magnesium alloy, Monel, and plastic
• Straight cylindrical 0.500-inch shank fits standard drill chucks and collet holders
• No pilot — allows flexible positioning for deburring and chamfering applications

Compatibility

Designed for use in drill presses, milling machines, and hand-held drilling equipment accepting a 0.500-inch straight cylindrical shank. Suitable for chamfering and countersinking operations on aluminum, brass, magnesium, magnesium alloy, Monel, high-nickel steel, and plastic workpieces.

Installation Notes

Installation and use should be performed by qualified machinists or skilled tradespeople familiar with rotating cutting tools. Secure the 0.500-inch shank firmly in a properly sized drill chuck or collet before operation and verify runout before cutting. Always power down and de-energize the machine spindle before changing or adjusting the tool. Follow the machine manufacturer's recommended speed and feed guidelines for the specific workpiece material to avoid tool damage or workpiece injury.
