M.a. Ford 92025001 Countersink 60 Degree 3 Flute Hss

Product Description

The M.A. FORD 92025001 is a single-end, three-flute countersink made from high-speed steel for right-hand cutting applications. It features a 60-degree included angle and a straight-cylindrical shank measuring 0.25 inches in diameter, with an overall length of 1.25 inches. The bright, uncoated finish suits general-purpose shop use where coating is not required. Machinists and fabricators use this tool for countersinking, chamfering, and deburring operations on a range of materials. The tip nose diameter is 0.07 inches. No pilot is included, and the tool is designed as a head-only countersink without a pilot guide.

This countersink is suited for use in manual or CNC drilling operations across light manufacturing, fabrication shops, and maintenance environments. It performs on soft to medium-hardness materials and is well matched to production runs requiring consistent chamfer geometry. The compact 1.25-inch overall length makes it practical for use in tight setups and standard drill chucks or quick-change holders that accept a 0.25-inch shank.

Key Features

• 60-degree included angle with 30-degree centerline angle for standard countersink geometry
• Three-flute design provides smooth cutting action and chip clearance
• High-speed steel construction for durability across a range of workpiece materials
• Bright, uncoated finish suitable for general-purpose countersinking without added coating cost
• Straight-cylindrical shank at 0.25 inches fits standard drill chucks and holders
• No pilot included — single end, head-only configuration for flexible positioning

Compatibility

Designed for chamfering, countersinking, and deburring operations on aluminum, brass, high-nickel steel, magnesium, magnesium alloy, Monel, and plastic workpieces. Accepts any standard drill press, lathe, or CNC spindle with a 0.25-inch shank capacity.

Installation Notes

This tool is installed by a machinist or toolroom technician into a drill press, milling machine, or CNC spindle that accepts a 0.25-inch straight shank. Ensure the machine is fully stopped and locked out before changing tooling. Set spindle speed appropriate for the workpiece material and tool diameter before engaging the cut. Do not exceed the tool manufacturer's recommended feed and speed parameters for the material being machined.
