M.a. Ford. 92200002 Countersink 82 Degree 3 Flute Hss

Product Description

The M.A. FORD. 92200002 is a single-end, 3-flute countersink designed for chamfering, countersinking, and deburring operations in a wide range of materials. Built from high-speed steel with a bright uncoated finish, it operates with right-hand cutting direction. The tool features an 82-degree included angle and a 3/4-inch straight-cylindrical shank, making it compatible with standard drill press and milling machine setups. Overall length is 4.25 inches, and the tip nose diameter measures 0.600 inches. This countersink is suited for production shops, tool rooms, and maintenance environments where consistent, clean entry holes are required.

This countersink is intended for use on aluminum, brass, magnesium, magnesium alloy, high-nickel steel, Monel, and plastic workpieces. It is well-suited for aerospace, general manufacturing, and fabrication applications where precise countersink geometry is needed to seat flat-head fasteners flush with the workpiece surface. The 3-flute design balances chip evacuation with surface finish quality, making it effective across both manual and CNC-assisted setups in light to medium production runs.

Key Features

• 82-degree included angle for standard flat-head fastener seating
• 3-flute geometry supports efficient chip removal and improved finish quality
• High-speed steel construction provides durability across non-ferrous and plastic materials
• Bright uncoated finish suitable for general-purpose cutting without coating-related material incompatibilities
• Straight-cylindrical shank at 3/4 inch fits standard collets and drill chucks
• Single-end design with no pilot included, allowing use with or without a separate pilot guide

Compatibility

Rated for use on aluminum, brass, high-nickel steel, magnesium, magnesium alloy, Monel, and plastic. Designed for use with standard 3/4-inch straight-shank tool holders in drill press, milling, and hand-operated setups.

Installation Notes

Countersinks of this type are installed by machinists and toolroom technicians using standard drill chucks or collet holders that accept a 3/4-inch straight shank. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Verify shank seating and runout before operation, as poor concentricity will produce oversized or irregular countersink geometry. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material.
