M.a. Ford. 92075002 Countersink 82 Degree 3 Flute Hss

Product Description

The M.A. FORD. 92075002 is a single-end, three-flute countersink designed for chamfering, countersinking, and deburring operations in metalworking and fabrication environments. Made from high-speed steel with a bright, uncoated finish, it features an 82-degree included angle and a straight cylindrical shank. The 0.75-inch head diameter and 0.5-inch shank diameter pair with a 3-inch overall length to suit standard drill press and CNC setups. This tool is installed and used by machinists, tool-and-die professionals, and maintenance technicians who need consistent, clean countersink profiles without a pilot.

This countersink is suited for light to medium production work on a range of materials including aluminum, brass, magnesium, magnesium alloy, high-nickel steel, Monel, and plastic. The right-hand cutting direction and straight-cylindrical shank make it compatible with standard drill chucks and collet holders. It is well-suited for sheet metal work, fixture fabrication, and general maintenance applications where an 82-degree countersink profile is specified — a common requirement for flat-head fastener seating per standard aerospace and industrial callouts.

Key Features

• 82-degree included angle (41-degree centerline angle) for standard flat-head fastener countersinking
• Three flutes for smooth chip evacuation and reduced chatter on non-ferrous and soft materials
• High-speed steel construction provides durability across the listed material applications
• Bright, uncoated finish — no coating buildup concerns on close-tolerance work
• No pilot required — fits standard drill chucks and collet holders directly
• Single-end design with a 0.23-inch tip diameter for clean entry on pre-drilled holes

Compatibility

Designed for use with aluminum, brass, magnesium, magnesium alloy, high-nickel steel, Monel, and plastic. Fits any drill press, hand drill, or CNC spindle accepting a 0.5-inch straight-cylindrical shank.

Installation Notes

This tool is installed and operated by machinists or maintenance technicians using standard drill chucks or collet holders. Always secure the workpiece and power down the spindle before changing tooling. Use appropriate cutting fluid or lubricant for the specific material being machined; dry cutting is generally acceptable for aluminum and plastics but verify for harder alloys. Follow shop safety and applicable OSHA machine-guarding requirements when operating rotary cutting tools.
