M.a. Ford. 78018706 Countersink 120 Degree 6 Flute Carbide

Product Description

The M.A. FORD. 78018706 is a solid carbide countersink designed for chamfering, countersinking, and deburring operations in metalworking and fabrication applications. Built with a 120-degree included angle and six flutes, this tool delivers clean, consistent results across a wide range of workpiece materials. The straight cylindrical shank measures 3/16 inches in diameter, and the overall length is 1.5 inches, making it well-suited for close-tolerance work in drill presses, CNC machining centers, and manual mills. Solid carbide construction provides rigidity and wear resistance across demanding cutting cycles.

This countersink is intended for use in machine shop, tool-and-die, and production environments where precise chamfer geometry is required. Its right-hand cutting direction and single-end design make it a standard choice for machinists and fabricators working with a broad spectrum of metals and non-metals. The 0.04-inch tip diameter allows entry into smaller pre-drilled holes for accurate seat preparation and edge cleanup.

Key Features

• 120-degree included angle for standard chamfer and countersink profiles
• Six-flute design for smooth cutting action and improved chip evacuation
• Solid carbide construction for rigidity and extended tool life
• Right-hand cutting direction, single-end configuration
• Straight cylindrical shank for broad machine compatibility
• No pilot required — simplifies setup and reduces tooling cost

Compatibility

Designed for use on alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel workpieces. Fits standard 3/16-inch collets and chucks.

Installation Notes

Installation and operation should be performed by a qualified machinist or tooling technician. Secure the shank firmly in a compatible collet or drill chuck before use and verify runout is within acceptable limits for the application. Always power down and de-energize the machine spindle before changing or inspecting tooling. Follow applicable shop safety procedures and machine manufacturer guidelines when setting speeds and feeds for carbide cutting tools.
