M.a. Ford. 78125003 Countersink 90 Deg 6 Flute Carbide

Product Description

The M.A. FORD. 78125003 is a solid carbide countersink designed for precision chamfering, countersinking, and deburring across a wide range of materials. It features a 90-degree included angle, a 1-1/4 inch head diameter, and a 6-flute right-hand cutting geometry that produces clean, consistent results in production and job-shop environments. The straight-cylindrical shank measures 1/2 inch in diameter and the tool runs 3 inches in overall length. The bright uncoated finish suits applications where coating interaction with the workpiece material is a concern. This tool is typically installed and operated by machinists, tool-and-die makers, and CNC operators.

This countersink is suited for use on alloy steel, mild steel, stainless steel, cast iron, high-tensile steel, high-nickel steel, Monel, aluminum, brass, magnesium, magnesium alloy, and plastic. It performs in both manual and CNC drilling operations where a 90-degree chamfer is required for fastener seating or edge preparation. The single-end, no-pilot design gives the operator direct control over centering, making it appropriate for use in drill presses, milling machines, and CNC machining centers.

Key Features

• 90-degree included angle (45-degree centerline angle) for standard fastener countersinking
• 6-flute geometry for smoother surface finish and reduced chatter
• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 1-1/4 inch head diameter accommodates larger fastener head profiles
• Bright uncoated finish compatible with a broad range of workpiece materials
• No-pilot, single-end design for flexible centering and setup

Compatibility

Designed as an OEM-style solid carbide countersink compatible with standard 1/2 inch straight-cylindrical shank toolholders used in drill presses, milling machines, and CNC machining centers performing chamfering, countersinking, and deburring operations.

Installation Notes

Install in a 1/2 inch collet or toolholder and confirm runout is within acceptable limits before engaging the workpiece. Secure the workpiece firmly before operation to prevent movement during cutting. Always wear appropriate eye and hand protection when operating rotary cutting tools. Follow applicable machine shop safety standards and equipment manufacturer guidelines for speeds and feeds based on workpiece material.
