Osg 404-562508 Square End Mill 9/16 in 4 Flute Solid Carbide

Product Description

The OSG 404-562508 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. It features a 9/16 inch cutting diameter with a 1-1/4 inch length of cut, a 9/16 inch shank diameter, and a 3-1/2 inch overall length. The four-flute, spiral design with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN (Titanium Carbonitride) coating increases surface hardness and wear resistance, extending tool life in ferrous and non-ferrous materials. Micrograin carbide construction provides the rigidity needed for tight-tolerance work. This tool is installed and operated by machinists and CNC operators in job shop, production, and toolroom settings.

The 404-562508 is suited for face milling, slotting, peripheral milling, and side milling operations on a wide range of workpiece materials. Its centercutting capability allows plunge entry, adding versatility for ramping and pocket operations. The right-hand cut and right-hand flute configuration is standard for conventional CNC machining centers and manual knee mills. The regular-length profile keeps overhang minimal, supporting rigidity in general-purpose milling applications.

Key Features

• Solid micrograin carbide construction for rigidity and dimensional stability
• TiCN coating for increased wear resistance and extended tool life
• 4-flute spiral design with 30-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge and ramping entry
• Right-hand cut, right-hand flute — standard orientation for CNC and manual mills
• Mill diameter tolerance of +0.000 / -0.001 inches for close-tolerance fitment

Compatibility

Designed as an OEM-style replacement and standard-fitment solid carbide square end mill for use in CNC machining centers, knee mills, and similar toolholding systems accepting a 9/16 inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the spindle is fully powered down and locked out before changing tooling. Verify shank seating depth and runout with a dial indicator before initiating a cut. Follow applicable shop safety standards and machine tool operating procedures when setting feeds and speeds.
