Osg 464-375011 Square End Mill 3/8 Inch 4 Flute Solid Carbide

Product Description

The OSG 464-375011 is a solid carbide square end mill designed for precision milling of ferrous and non-ferrous materials. It carries a TiAlN (titanium aluminum nitride) coating that improves heat resistance and extends tool life in high-temperature cutting environments. The 4-flute, 30-degree spiral helix geometry supports efficient chip evacuation while delivering a fine surface finish. At 0.375 inches in diameter with a 1.125-inch length of cut, this tool is well suited for slotting, profiling, and peripheral milling operations. It is installed and operated by machinist trades on CNC machining centers and manual mills.

This end mill fits standard milling applications in job shops, production facilities, and toolrooms requiring a long-series 3/8-inch carbide tool. The centercutting design allows plunge entry, adding versatility in pocketing and ramping operations. Right-hand cut and right-hand flute orientation make it compatible with conventional spindle setups. The micrograin carbide substrate provides edge toughness for demanding cuts in steel, stainless, cast iron, aluminum, and similar materials.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiAlN coating for elevated heat resistance and longer tool life
• 4 flutes with 30-degree helix angle for balanced chip flow and surface finish
• Centercutting geometry allows direct plunge and ramp entry
• Right-hand cut, right-hand flute for standard spindle compatibility
• Long-series length of cut suits deeper pockets and extended-reach applications

Compatibility

Designed as a direct-fit replacement or standard tooling selection for 3/8-inch collet chucks, end mill holders, and hydraulic chucks on CNC machining centers and manual knee mills requiring a 3/8-inch shank, long-series solid carbide square end mill.

Installation Notes

Installation is performed by qualified machinists. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the holder and torque the retention mechanism per the holder manufacturer specification. Inspect the collet or holder bore for wear or runout before securing the tool, as excessive runout will reduce tool life and part accuracy.
