M.a. Ford 67025002 82 Degree Hss Countersink 1/4 in

Product Description

The M.A. FORD 67025002 is a single-end, zero-flute countersink designed for chamfering, countersinking, and deburring operations. Constructed from high-speed steel with a bright uncoated finish, it features an 82-degree included angle and a 1/4-inch straight cylindrical shank. The zero-flute design produces a smooth, chatter-free cutting action that is well suited to hand-held or low-speed machine applications. Overall length is 2 inches. This tool is handled and installed by machinists, toolroom technicians, and maintenance professionals working with a wide range of base materials in production and job-shop environments.

The 67025002 is appropriate for use on ferrous and non-ferrous materials including mild steel, alloy steel, stainless steel, cast iron, high-tensile steel, high-nickel steel, Monel, aluminum, brass, magnesium, magnesium alloy, and plastic. The 82-degree included angle matches fastener head geometry common in aerospace and general-purpose countersunk hardware. Its compact 2-inch overall length makes it practical for use in drill presses, CNC machining centers, and handheld power tools where clearance is limited.

Key Features

• 82-degree included angle with 41-degree centerline angle for standard countersunk fastener seating
• Zero-flute construction minimizes chatter and produces a smooth countersink finish
• High-speed steel body provides durability across a broad range of workpiece materials
• Bright uncoated finish suitable for general-purpose shop use without added coating cost
• 1/4-inch straight cylindrical shank for compatibility with standard collets and drill chucks
• Single-end design rated for chamfering, countersinking, and deburring tasks

Compatibility

Designed as a general-purpose countersink for use in standard 1/4-inch collets and drill chucks. Compatible material applications include alloy steel, aluminum, brass, cast iron, high-nickel steel, high-tensile steel, magnesium, magnesium alloy, mild steel, Monel, plastic, and stainless steel.

Installation Notes

Installation and use of this tool is typically performed by machinists or maintenance technicians. Secure the shank firmly in the collet or chuck and verify concentricity before running. Reduce spindle speed when working harder materials such as stainless or high-nickel alloys to prevent premature wear. Do not exceed the tool's rated maximum cutting diameter of 0.23 inches.
