Osg 5360500 Square End Mill 3/8 in 3 Flute Cobalt Long

Product Description

The OSG 5360500 is a cobalt square end mill designed for milling ferrous and hard metals in machining center and manual mill applications. Built from M42 cobalt high-speed steel, this single-end tool delivers a 3/8 inch cutting diameter with a 1-1/2 inch length of cut and a 30-degree helix angle that promotes efficient chip evacuation and smooth cutting action. The spiral flute geometry and centercutting capability allow the tool to plunge directly into the workpiece. Machinists and tool-and-die professionals select this series for general-purpose material removal where toughness and heat resistance are priorities.

This end mill is suited for both CNC machining centers and manual milling machines in job shop, maintenance, and production environments. The long length classification makes it useful in applications requiring extended reach beyond what standard-length tools can access. The 3/8 inch shank diameter matches common collet and end mill holder sizes, and the right-hand cut with right-hand flute orientation is the standard configuration for conventional and climb milling on most machines.

Key Features

• M42 cobalt HSS construction for improved heat and wear resistance compared to standard M2 HSS
• 30-degree helix angle promotes chip flow and reduces cutting forces
• Centercutting design allows direct plunge entry into the workpiece
• Three-flute geometry balances chip clearance and tool rigidity
• Uncoated finish suitable for use with cutting fluids on a wide range of materials
• Long series length provides extended reach for deeper features

Compatibility

Designed as an OEM-style replacement or direct substitute for 3/8 inch shank square end mill applications in OSG Series 536. Compatible with standard 3/8 inch collets and end mill holders used in CNC and manual milling setups.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Secure the shank to the full recommended engagement depth in the collet or holder and verify runout with a dial indicator before beginning the cut. Follow applicable shop safety procedures for rotating cutting tools.
