Osg 3132508 Square End Mill 0.0591 in 2 Flute Solid Carbide

Product Description

The OSG 3132508 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 0.0591-inch (1.5 mm) cutting diameter and a 0.0906-inch (2.3 mm) length of cut, making it well suited for tight-tolerance slots, pockets, and peripheral milling in small-feature work. The 0.1575-inch (4.0 mm) shank provides a stable grip in standard collets. Two right-hand flutes with a 30-degree helix angle promote efficient chip evacuation. The WXL coating enhances wear resistance and extends tool life in ferrous and non-ferrous materials. Licensed machinists and CNC operators are the primary installers of this tool.

This end mill is appropriate for use in vertical machining centers, CNC mills, and manual knee mills where small-diameter, high-precision cutting is required. The extended-reach geometry and centercutting capability allow it to enter material axially and mill in confined areas. It is commonly used in mold and die work, aerospace component machining, and precision part production where tight tolerances and fine finishes are required. The micrograin carbide substrate supports high cutting speeds in hardened and abrasive materials.

Key Features

• 0.0591-inch (1.5 mm) cutting diameter for small-feature and fine-detail milling
• Solid micrograin carbide construction for rigidity and wear resistance
• WXL coating for extended tool life in ferrous and non-ferrous materials
• 30-degree helix angle with right-hand flute and right-hand cut configuration
• Centercutting design allows direct plunge entry into workpiece material
• Extended-reach geometry for access to deep or confined milling locations

Compatibility

Designed as a standard-shank solid carbide square end mill with a 0.1575-inch shank diameter, compatible with ER and straight-bore collet systems accepting 4.0 mm shank tooling in CNC and manual milling machines.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Ensure the machine spindle is fully powered down and locked before changing tooling. The shank must be clean and fully seated in the collet or tool holder to the recommended grip depth before tightening. Inspect the cutting edges under magnification before use, as solid carbide end mills at this diameter are susceptible to chipping if mishandled.
