Osg 5323100 Square End Mill 3/4 in Cobalt 3 Flute

Product Description

The OSG 5323100 is a cobalt double-end square end mill designed for high-performance milling in ferrous and difficult-to-machine materials. Built from M42 cobalt high-speed steel, this tool delivers strong wear resistance and heat tolerance compared to standard HSS tooling. It features a 3/4 inch cutting diameter, a 1-5/8 inch length of cut, and a 30-degree right-hand spiral flute geometry. The uncoated finish is suitable for applications where re-sharpening is routine. Three flutes provide a balance of chip clearance and rigidity, making this mill well suited for profiling, slotting, and side milling operations in shop and production environments.

This end mill is intended for use in vertical machining centers, knee mills, and manual or CNC milling machines where a 3/4 inch shank is the standard toolholder bore. The double-end design extends tool life by providing two usable cutting ends on a single body. At 5-5/8 inches overall length with a regular-length classification, this tool fits standard tool length requirements without extended-reach concerns. Machinists and toolroom operators performing general-purpose milling in steel, stainless, and cast iron will find this configuration a reliable choice within the OSG Series 532 line.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• Double-end design provides two cutting ends per tool, reducing per-edge cost
• 30-degree helix angle with right-hand cut and right-hand flute orientation
• Centercutting geometry allows plunge entry into workpiece
• Spiral flute configuration promotes efficient chip evacuation
• Uncoated finish supports easy re-sharpening in toolroom settings

Compatibility

Designed for use in milling machines and machining centers accepting a 3/4 inch straight shank toolholder. Part of the OSG Series 532 cobalt square end mill product line.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Secure the shank fully in a collet or end mill holder to the minimum recommended grip depth before operation. Confirm spindle speed and feed rate are set per the material being machined before engaging the cut. Inspect both cutting ends for damage before use and after re-sharpening.
