M.a. Ford. 92062506 Countersink 120 Degree 3 Flute Hss

Product Description

The M.A. FORD. 92062506 is a 3-flute, single-end countersink designed for precision chamfering and countersinking operations in metalworking and fabrication environments. Built from high-speed steel throughout, it features a 120-degree included angle and a 5/8-inch head diameter, making it well suited for creating clean, properly angled seat profiles for flat-head fasteners. The straight cylindrical shank measures 1/4 inch in diameter, and the tool runs 2.25 inches in overall length. Licensed machinists, tool-and-die technicians, and maintenance tradespeople are the primary users in shop and field settings.

This countersink is rated for use across a range of workpiece materials including aluminum, brass, magnesium, magnesium alloy, high-nickel steel, Monel, and plastic. Its 3-flute geometry helps reduce chatter and produces a smoother finish than single-flute styles. Typical applications include deburring drilled holes, pre-seating flat-head screws and bolts, and chamfering edge entries on sheet metal, plate, and machined components in both production and maintenance-repair settings.

Key Features

• 120-degree included angle for standard flat-head fastener seating
• 3-flute design reduces chatter and improves surface finish
• High-speed steel construction for durability across a broad material range
• Straight cylindrical 1/4-inch shank fits standard drill chucks and collets
• Single-end geometry for straightforward tool changes
• Right-hand cutting direction compatible with conventional drill press and hand-drill operation

Compatibility

Rated for use in aluminum, brass, magnesium, magnesium alloy, high-nickel steel, Monel, and plastic. Fits any standard drill chuck or collet accepting a 1/4-inch straight cylindrical shank.

Installation Notes

Secure the shank firmly in the drill chuck or collet before operation and verify runout is within acceptable limits to prevent premature wear. Power down and de-energize the drill press or CNC spindle before mounting or removing the tool. Use appropriate cutting fluid for the workpiece material when countersinking harder alloys such as high-nickel steel or Monel. Follow applicable shop safety standards and wear eye protection during all cutting operations.
