Osg 464-125011 Square End Mill 1/8 in 4 Flute Solid Carbide

Product Description

The OSG 464-125011 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built to Series 464 specifications, it features a 1/8-inch diameter, a 3/4-inch length of cut, and an overall length of 2-1/4 inches. The 4-flute geometry with a 30-degree helix angle and TiAlN coating supports efficient chip evacuation and extended tool life in ferrous and non-ferrous materials. The micrograin carbide substrate provides the hardness and rigidity needed for tight-tolerance work in production and job-shop environments. Licensed machinists and CNC operators select this tool for slotting, profiling, and peripheral milling where dimensional accuracy is critical.

This end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills where a 1/8-inch shank is accommodated. The long-length designation and centercutting capability allow it to plunge directly into the workpiece and reach into features with moderate depth requirements. It is appropriate for finish and semi-finish passes on steel, stainless steel, aluminum, and similar materials in both production and prototype settings.

Key Features

• Solid micrograin carbide construction for hardness and wear resistance
• TiAlN finish for thermal protection and extended tool life at elevated cutting speeds
• 4-flute spiral design with 30-degree helix for smooth chip flow
• Centercutting geometry allows direct plunge entry
• Right-hand cut, right-hand flute configuration for standard spindle operation
• Mill diameter tolerance of +0.000 / -0.001 inches for consistent fit in close-tolerance work

Compatibility

Designed as a standard 1/8-inch shank end mill compatible with collet chucks, end mill holders, and shrink-fit tooling systems sized for 1/8-inch shanks on CNC and manual milling machines.

Installation Notes

Installation and tool changes must be performed with the machine spindle at a full stop and the control in a locked or e-stop state. Use a properly sized collet or holder to achieve full shank engagement and minimize runout. Inspect the shank and cutting edges for chips or damage before seating the tool. Follow the machine manufacturer and tooling supplier recommendations for speeds, feeds, and depth of cut appropriate to the workpiece material.
