M.a. Ford 78100002 Countersink 82 Degree 6 Flute Carbide

Product Description

The M.A. FORD 78100002 is a solid carbide countersink designed for precision chamfering, countersinking, and deburring operations across a wide range of materials. Built with 6 flutes and an 82-degree included angle, it delivers smooth, chatter-resistant cutting in both manual and CNC machining environments. The 1/2-inch straight-cylindrical shank fits standard drill chucks and collet holders. At 2-3/4 inches overall length and a 1-inch head diameter, this tool is sized for production and maintenance work requiring consistent, clean countersink profiles. Machinists, toolroom operators, and maintenance technicians are the primary users of this tool.

This countersink is suited for use on alloy steel, mild steel, stainless steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, Monel, and plastic. The 82-degree included angle matches the standard fastener head geometry common in aerospace and general-purpose machining. It is a single-end tool with no pilot included, making it appropriate for use in drill presses, milling machines, and CNC machining centers where the operator controls alignment through fixturing or piloted adapters.

Key Features

• 82-degree included angle matches common flat-head fastener geometry for aerospace and general machining
• 6-flute design reduces chatter and produces a finer surface finish compared to fewer-flute alternatives
• Solid carbide construction provides hardness and wear resistance across a broad material range
• 1/2-inch straight-cylindrical shank fits standard collet chucks and drill press spindles
• Right-hand cutting direction for conventional spindle rotation
• No pilot required, allowing use in a variety of machine setups

Compatibility

Designed as an OEM-style countersink for use in drill presses, milling machines, and CNC machining centers accepting a 1/2-inch straight-cylindrical shank.

Installation Notes

Installation and operation should be performed by qualified machinists or toolroom personnel familiar with rotating cutting tools. Secure the shank fully in the collet or chuck before starting the spindle, and verify runout before cutting production parts. Use appropriate cutting speeds and feeds for the workpiece material to avoid tool chipping or workpiece damage. Always power down and lock out the machine before changing or inspecting the tool.
