M.a. Ford. 92025002 Countersink 82 Degree 3 Flute Hss

Product Description

The M.A. FORD. 92025002 is a single-end, 3-flute countersink machined from high-speed steel and designed for right-hand cutting applications. It carries an 82-degree included angle, making it the standard choice for flat-head fastener seating in aerospace and general metalworking setups. The straight-cylindrical shank measures 1/4 inch in diameter, and the overall length is 1.25 inches. The bright, uncoated finish keeps the tool ready to run without additional surface prep. Licensed machinists and tooling specialists typically reach for this countersink when precision chamfering, deburring, or countersinking is required on a range of workpiece materials.

This countersink is suited for use on aluminum, brass, magnesium, magnesium alloy, high-nickel steel, Monel, and plastic. Its 3-flute geometry provides a balance of chip clearance and surface finish quality across these materials. The 82-degree included angle aligns with flat-head machine screw standards common in aerospace and light manufacturing assemblies. It is equally effective in manual drill press setups and CNC tooling applications where a small-diameter countersink is specified. The tool does not include a pilot and is designed for single-end use only.

Key Features

• 82-degree included angle for flat-head fastener seating per common aerospace and machine screw standards
• 3-flute design balances chip evacuation with a smooth finished surface in the countersunk seat
• High-speed steel construction provides durability across both ferrous and non-ferrous workpiece materials
• 1/4 inch straight-cylindrical shank fits standard drill chucks and collet holders without adapters
• Bright, uncoated finish — no post-processing required before use
• Suitable for chamfering, countersinking, and deburring operations in a single tool

Compatibility

Designed for use on aluminum, brass, magnesium, magnesium alloy, high-nickel steel, Monel, and plastic workpieces. Fits any drill press, hand drill, or CNC spindle accepting a 1/4 inch straight-cylindrical shank.

Installation Notes

This tool is installed and operated by machinists, toolroom technicians, or trained fabricators. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable tolerance for the application. Power down and lock out the machine spindle before changing or inspecting the tool. Do not exceed the recommended feed and speed parameters for the workpiece material being machined.
