M.a. Ford 92050002 Countersink 82 Degree 3 Flute Hss

Product Description

The M.A. FORD 92050002 is a single-end, three-flute countersink designed for chamfering, countersinking, and deburring operations in machine shop and fabrication environments. Built from high-speed steel (HSS) with a bright, uncoated finish, this tool features an 82-degree included angle — a standard angle for aerospace and general-purpose fastener seating. The 1/4-inch straight-cylindrical shank fits standard drill chucks and collet holders, while the 2.25-inch overall length provides adequate reach for most benchtop and floor-standing drilling applications. Machinists, tool-and-die technicians, and production drill press operators are the primary users of this tool.

This countersink is well suited for light-to-medium duty countersinking in aluminum, brass, magnesium, magnesium alloy, plastic, high-nickel steel, and Monel. The three-flute geometry provides a balance between chip clearance and surface finish quality, making it appropriate for both production runs and one-off part work. It does not include a pilot, and the end type is single, meaning it is intended for use without a guide bushing in applications where the operator maintains alignment manually or through a fixture.

Key Features

• 82-degree included angle (41-degree centerline angle) for standard fastener seat geometry
• Three-flute design balances chip evacuation and finish quality
• High-speed steel construction handles a wide range of non-ferrous and engineered materials
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• 1/4-inch straight-cylindrical shank for broad chuck and collet compatibility
• No pilot required — suits fixture-guided or operator-aligned setups

Compatibility

Suitable for use in aluminum, brass, magnesium, magnesium alloy, plastic, high-nickel steel, and Monel. Designed for standard drill chucks and collet holders accepting a 1/4-inch straight-cylindrical shank.

Installation Notes

This tool is intended for use by machinists and skilled tradespeople familiar with rotating cutting tools. Secure the shank firmly in a drill chuck or collet before operation and confirm runout is within acceptable limits for the application. Always power down and lock out the spindle before tool changes. Do not exceed the recommended feed and speed parameters for the workpiece material.
