M.a. Ford. 78062502 Solid Carbide Countersink 82 Degree 6 Flute

Product Description

The M.A. FORD. 78062502 is a solid carbide countersink designed for chamfering, countersinking, and deburring operations across a wide range of materials. It features an 82-degree included angle and 6 flutes, delivering smooth, accurate cone geometry in a single pass. The 3/8-inch straight-cylindrical shank fits standard drill chucks and collet holders. With an overall length of 2.375 inches and a bright, uncoated finish, this tool is built for precision work on the machine shop floor or production line. Machinists and metalworking professionals install this tool in CNC machining centers, drill presses, and hand-held pneumatic drills.

This countersink is suited for use on alloy steel, mild steel, stainless steel, cast iron, aluminum, brass, magnesium, magnesium alloy, high-nickel steel, high-tensile steel, Monel, and plastic. The 82-degree included angle matches the standard fastener head geometry commonly required in aerospace and general metalworking applications. It is a single-end tool with no pilot and no countersink head-only configuration, making it a straightforward drop-in for production countersinking setups.

Key Features

• 82-degree included angle matches standard flat-head fastener geometry
• 6-flute design reduces chatter and produces a cleaner finish than lower flute-count tools
• Solid carbide construction provides hardness and wear resistance for extended tool life
• Bright/uncoated finish suitable for use across a broad range of workpiece materials
• 3/8-inch straight-cylindrical shank for compatibility with standard toolholding systems
• No pilot required — functions as a standalone countersinking tool

Compatibility

Designed 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. Fits any toolholder accepting a 3/8-inch straight-cylindrical shank.

Installation Notes

Installation is performed by machinists using a drill press, CNC machining center, or pneumatic drill equipped with a collet or drill chuck sized for a 3/8-inch shank. Secure the shank fully within the toolholder and verify runout before cutting. Set spindle speed according to the workpiece material and tool diameter per standard machining practice. Always power down and lock out the machine before changing tooling.
