M.a. Ford. 61T025003 Single Flute Countersink 90 Degree Hss

Product Description

The M.A. FORD. 61T025003 is a single-flute, 90-degree countersink designed for clean, precise chamfering and countersinking in a wide range of materials. Constructed from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during cutting. The straight-cylindrical shank measures 0.25 inches in diameter, with an overall length of 2 inches. The maximum cutting diameter is 0.25 inches. This tool is installed and used by machinists, maintenance technicians, and trade professionals working with hand drills, drill presses, and CNC equipment.

The 61T025003 countersink is suited for deburring, chamfering, and preparing holes for flat-head fasteners across a broad spectrum of materials. Verified 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. Its single-flute geometry produces a smooth finish and minimizes chatter, making it well-suited for both production environments and maintenance repair operations. Right-hand cutting direction is standard.

Key Features

• 90-degree included angle for standard flat-head fastener seat preparation
• Single-flute design reduces chatter and improves surface finish quality
• TiN coating extends tool life and reduces heat buildup during operation
• High-speed steel construction handles a wide range of ferrous and non-ferrous materials
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Compact 2-inch overall length suits tight-clearance applications

Compatibility

Designed for use in standard drill chucks, collets, and ER toolholders accepting a 0.25-inch straight-cylindrical shank. Suitable for hand drills, drill presses, and CNC machining centers performing countersinking operations.

Installation Notes

Install this countersink into a properly sized chuck or collet and secure firmly before operation. Ensure the workpiece is clamped securely to prevent movement during cutting. Apply cutting fluid when working with stainless steel, high-nickel alloys, or other difficult materials to manage heat and prolong tool life. Inspect the cutting edge for wear before each use and replace the tool if chipping or dullness is observed.
