Osg 404-433111 Square End Mill 0.4331 in 4 Flute Carbide

Product Description

The OSG 404-433111 is a solid carbide square end mill designed for precision milling operations in metal and alloy workpieces. Part of OSG Series 404, it features a 0.4331 inch cutting diameter, a 0.9843 inch length of cut, and a four-flute spiral configuration with a 30-degree helix angle. The micrograin carbide substrate and TiAlN coating provide heat and wear resistance for high-speed cutting in ferrous and non-ferrous materials. This is a single-end, center-cutting tool with right-hand cut and right-hand flute direction. Machinists and tool-and-die professionals use this end mill in CNC machining centers and manual mills for slotting, profiling, and peripheral milling.

This end mill is suited for use in job shops, production machining environments, and tool rooms where a regular-length, standard-reach carbide end mill is required. The 0.4331 inch shank diameter matches the cutting diameter, making it compatible with standard collet and end mill holders sized for 11 mm or 0.4331 inch shanks. The TiAlN coating extends tool life in dry or semi-dry cutting conditions and performs well in hardened steels, stainless, and cast iron.

Key Features

• 0.4331 inch cutting diameter with matching 0.4331 inch shank diameter for direct collet mounting
• 0.9843 inch length of cut suitable for moderate-depth slotting and profiling
• Solid micrograin carbide construction for rigidity and edge retention
• TiAlN coating for thermal resistance and extended tool life in ferrous materials
• 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Center-cutting design allows plunge entry without pre-drilled pilot holes

Compatibility

Designed as a standard-shank square end mill for use in CNC machining centers and manual milling machines equipped with collet chucks or end mill holders accepting an 11 mm or 0.4331 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling practices. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended engagement depth in the collet or holder to minimize runout and prevent pullout under load. Verify tool runout with a dial indicator before beginning a production cut.
