Osg 464-500011 Square End Mill 1/2 in 4 Flute Solid Carbide

Product Description

The OSG 464-500011 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 0.5 inch cutting diameter, a 2 inch length of cut, and a 4 inch overall length with a 0.5 inch shank diameter. The tool carries a TiAlN finish that improves heat resistance and tool life in high-speed cutting conditions. With 4 spiral flutes ground at a 30-degree helix angle and a micrograin carbide substrate, this end mill delivers consistent chip evacuation and surface finish. It is centercutting, allowing direct plunge entry into the workpiece. Right-hand cut and right-hand flute geometry make it compatible with standard CNC and manual milling machine spindles.

This end mill is suited for milling operations on ferrous and non-ferrous metals including steel, stainless steel, cast iron, and aluminum alloys. The long-length configuration provides additional reach for deeper pockets, slots, and profiling passes. It is used in job shops, production machining environments, and toolrooms where consistent dimensional accuracy is required. Machinists and CNC operators working on vertical and horizontal machining centers will find the OSG Series 464 geometry appropriate for general-purpose and finish milling tasks.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiAlN coating for elevated heat resistance and extended tool life
• 4 spiral flutes with 30-degree helix angle for smooth chip flow
• Centercutting design allows direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute for standard spindle compatibility
• Long-length series with 2 inch LOC suitable for deep pocket and slot work

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills with ER, R8, or equivalent collet systems accepting a 0.5 inch shank diameter. Part of the OSG Series 464 long-length square end mill family.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and locked out per facility safety procedures. Ensure the collet or tool holder is clean and within tolerance before seating the shank. Confirm runout with a dial indicator before beginning a cut, especially for finish milling passes. Follow the tool manufacturer recommended speeds and feeds for the specific workpiece material to avoid premature tool wear or breakage.
