Osg 464-437508 Square End Mill 7/16 in 4 Flute Solid Carbide

Product Description

The OSG 464-437508 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. Part of OSG's Series 464, this end mill features a 7/16 inch (0.4375 inch) mill diameter, a 2 inch length of cut, and a 4 inch overall length. The TiCN (Titanium Carbonitride) finish improves surface hardness and wear resistance compared to uncoated carbide tools. Micrograin carbide construction provides a fine grain structure that supports sharp cutting edges and extended tool life. This is a right-hand cut, right-hand flute, centercutting tool, meaning it can be used for plunge entry as well as side and slot milling. Machinists and CNC operators in job shops, production facilities, and toolrooms are the primary users of this tool.

This end mill is suited for milling ferrous and non-ferrous metals where a TiCN coating provides an advantage in abrasion resistance. The long-length classification with a 2 inch length of cut supports applications that require reaching into deeper pockets or slots where a standard-length end mill would fall short. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces during peripheral and slot milling operations. The 7/16 inch shank diameter matches the cutter diameter, making it compatible with standard ER collet chucks, end mill holders, and shrink-fit tooling in that bore size.

Key Features

• Solid micrograin carbide construction for sharp edges and extended tool life
• TiCN finish for improved wear resistance and surface hardness
• 4-flute, spiral flute geometry with a 30-degree helix angle for efficient chip evacuation
• Centercutting design allows plunge milling without a pre-drilled entry hole
• Right-hand cut and right-hand flute configuration for standard CNC and manual mill use
• Long-length classification with 2 inch LOC for deeper pocket and slot applications

Compatibility

Designed for use in CNC machining centers and manual mills equipped with toolholders accepting a 7/16 inch shank diameter, including ER collet chucks, end mill holders, and shrink-fit systems. Part of OSG Series 464.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before loading or unloading the tool. Seat the shank fully into the toolholder to the recommended insertion depth before tightening to avoid runout and premature tool failure. Verify spindle speed and feed rate parameters against the material being cut before starting the operation.
