M.a. Ford 60037503 Countersink 90 Degree 1 Flute Carbide

Product Description

The M.A. FORD 60037503 is a single-flute solid carbide countersink designed for producing clean, accurate 90-degree countersunk seats in a wide range of materials. With a 3/8-inch head diameter, a 1/4-inch straight cylindrical shank, and a 2-inch overall length, this tool is built for precision deburring and countersinking in production and job-shop environments. The uncoated bright finish suits general-purpose use without the added cost of a coating layer. Machinists, toolmakers, and CNC operators working in metalworking and fabrication applications install and use this tool routinely.

This countersink is suited for both manual and CNC drilling operations where a 90-degree included angle seat is required. Its single-flute geometry reduces chatter and produces a smoother finish compared to multi-flute designs, making it a reliable choice when surface finish quality at the countersunk bore matters. It is used across industries including aerospace fabrication, general machining, and sheet metal work.

Key Features

• 90-degree included angle with 45-degree centerline angle for standard countersunk fastener seating
• Single-flute design minimizes chatter and improves surface finish quality
• Solid carbide construction provides rigidity and wear resistance
• 3/8-inch head diameter with a 1/4-inch straight cylindrical shank for broad compatibility with standard tool holders and collets
• Bright/uncoated finish suitable for a wide range of materials without coating-related adhesion concerns
• Tip/nose diameter of 0.060 inches for accurate starting engagement

Compatibility

Designed for countersinking operations in alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel. Fits standard 1/4-inch collets and tool holders.

Installation Notes

This tool is installed by machinists and toolroom professionals in CNC machining centers, drill presses, or hand-held drilling equipment accepting a 1/4-inch straight shank. Secure the shank fully in the collet or chuck before operation and verify runout is within acceptable limits for the application. Always bring the spindle to a complete stop before changing or adjusting tooling. Follow applicable shop safety procedures and machine manufacturer guidelines during setup and use.
