M.a. Ford. 61T075003 Single Flute Countersink 3/4 Inch

Product Description

The M.A. FORD. 61T075003 is a single-flute, 90-degree countersink designed for precise chamfering and deburring operations in metal, plastic, and composite materials. Built from high-speed steel with a titanium nitride (TiN) coating, it offers extended tool life and reduced friction during cutting. The straight-cylindrical shank measures 1/2 inch in diameter and seats securely in standard chucks and collets. Maximum cutting diameter is 3/4 inch, and overall length is 2.75 inches. The 90-degree included angle is the standard for most fastener seat prep across industrial and fabrication applications. Licensed machinists, toolmakers, and maintenance technicians are the primary installers.

This countersink is suited for use in manual drill presses, CNC machining centers, and handheld power tools where precise countersink geometry is required. It handles a broad range of workpiece materials including mild steel, alloy steel, stainless steel, cast iron, aluminum, brass, magnesium, magnesium alloy, high-tensile steel, high-nickel steel, Monel, and plastic. The single-flute design reduces chatter and produces a cleaner finish compared to multi-flute alternatives, making it a practical choice for applications where surface finish quality is critical.

Key Features

Compatibility

Designed as an OEM-style replacement single-flute countersink compatible with standard drill presses, CNC machining centers, and handheld power tools accepting a 1/2 inch straight-cylindrical shank.

Installation Notes

Installation is performed by machinists or toolroom technicians. Secure the shank fully in the chuck or collet before operating and verify that the tool is running true to avoid runout-induced chatter. Always power down and lock out the machine before changing tooling. Follow applicable shop safety and OSHA machine-guarding requirements when operating rotary cutting tools.
