M.a. Ford 92125003 Countersink 90 Deg 3 Flute Hss 1-1/4 in

Product Description

The M.A. FORD 92125003 is a single-end, 3-flute countersink designed for chamfering, countersinking, and deburring operations in metal and plastic materials. Built from high-speed steel with a bright uncoated finish, it features a 90-degree included angle and a 45-degree centerline angle. The 1-1/4 inch head diameter and 5/8 inch straight-cylindrical shank make it compatible with standard drill press and milling machine setups. With a 2-3/4 inch overall length, it suits a range of production and maintenance machining applications. Machinists and tool-and-die professionals working in job shops or maintenance environments will find this a direct-fit cutting tool for everyday countersink work.

This countersink is suited for use on aluminum, brass, magnesium, magnesium alloy, high-nickel steel, Monel, and plastic workpieces. It is appropriate for both manual and CNC machine tool setups where a right-hand cutting direction is required. The single-end design without a pilot keeps setup simple for operators who locate the countersink by eye or with a guide bushing. Typical applications include preparing fastener seats, chamfering drilled holes, and removing burrs from machined edges in light manufacturing, fabrication, and maintenance-repair operations.

Key Features

• 90-degree included angle with 45-degree centerline angle for standard fastener seat preparation

• No pilot included, allowing flexible positioning for chamfering and deburring tasks

Compatibility

Designed as an OEM-style single-end countersink for use in drill presses, milling machines, and CNC machining centers accepting a 5/8 inch straight-cylindrical shank. Compatible workpiece materials include aluminum, brass, high-nickel steel, magnesium, magnesium alloy, Monel, and plastic.

Installation Notes

Installation and use should be performed by qualified machinists familiar with rotary cutting tool safety. Ensure the machine spindle is fully stopped and locked out before securing or removing the countersink from the tool holder. Verify shank seating and tool holder clamping before beginning any cutting operation. Follow applicable shop safety standards and machine manufacturer guidelines for speeds, feeds, and workholding when using rotary countersinks.
