Osg 5229500 Square End Mill 13/32 in 2 Flute Cobalt

Product Description

The OSG 5229500 is a double-end cobalt square end mill designed for milling operations on ferrous and non-ferrous metals. Built from M42 cobalt high-speed steel, this tool delivers heat resistance and edge retention that standard HSS tooling cannot match. It features a 13/32-inch cutting diameter, a 13/16-inch length of cut, and a 30-degree right-hand helix for efficient chip evacuation. The double-end configuration extends tool life by providing two usable cutting ends. Machinists and tool-and-die professionals working on manual mills, knee mills, and CNC machining centers will find this a reliable general-purpose end mill for slotting, profiling, and light contouring work.

This end mill is suited for job shops, production floors, and maintenance machining applications where a right-hand, centercutting tool is required. The bright uncoated finish makes it well-suited for non-ferrous materials, soft steels, and applications where coating adhesion to the workpiece is a concern. The regular-length geometry keeps deflection low during standard-depth passes. With a 1/2-inch shank diameter and 3-3/4-inch overall length, it fits standard collet chucks and end mill holders common in most shop setups.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• Double-end design provides two cutting ends per tool
• 30-degree right-hand spiral helix promotes smooth chip flow
• Centercutting geometry allows plunge entry into the workpiece
• Bright uncoated finish suitable for non-ferrous and soft ferrous materials
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as a general-purpose square end mill for use in standard end mill holders and collet chucks accepting a 1/2-inch shank diameter on manual and CNC milling machines.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Seat the shank to the recommended insertion depth in the holder and torque set screws to the holder manufacturer's specification. Confirm runout with a dial indicator before beginning the cut.
