M.a. Ford. 78012506 Solid Carbide Countersink 120 Degree 6 Flute

Product Description

The M.A. FORD. 78012506 is a solid carbide countersink designed for chamfering, countersinking, and deburring operations across a wide range of workpiece materials. Built with a 120-degree included angle and 6 flutes, it delivers clean, consistent results in both manual and machine setups. The straight cylindrical shank measures 0.125 inches in diameter with a 1.5-inch overall length and a tip diameter of 0.030 inches. Right-hand cutting geometry makes it compatible with standard drill press and CNC spindle rotation. Machinists, tool and die technicians, and fabrication shops will find this tool well-suited for precision hole finishing work.

This countersink is used in applications requiring accurate chamfer angles and smooth deburring without a pilot. Its 120-degree geometry is common in aerospace, general metalworking, and fabrication environments where fastener seat preparation and edge breaking are routine tasks. The single-end design keeps the tool compact for use in tight setups or small-diameter hole finishing. It is appropriate for both bench-mounted and CNC-controlled operations across a broad range of materials.

Key Features

• 120-degree included angle for standard chamfer and fastener seat geometry
• 6-flute design provides smooth cutting action and improved chip evacuation
• Solid carbide construction for wear resistance and dimensional stability across hard and abrasive materials
• 0.125-inch straight cylindrical shank fits standard collets and tool holders
• No pilot required, allowing use across varying hole diameters without pilot changes
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Suitable for chamfering, countersinking, and deburring operations in alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel workpieces.

Installation Notes

This tool is intended for use by machinists and tooling technicians in machine shop or fabrication environments. Secure the shank fully in a collet or tool holder before operation and verify that spindle rotation matches the right-hand cutting direction. Ensure workpiece is clamped securely before engaging the countersink to prevent chatter or tool deflection. Follow shop safety procedures and appropriate speeds and feeds for the workpiece material being machined.
