Osg 5823100 Square End Mill 0.748 in 2 Flute Cobalt

Product Description

The OSG 5823100 is a cobalt square end mill designed for milling operations requiring a durable, heat-resistant cutting tool. Built from M42 cobalt high-speed steel, this double-end mill delivers reliable performance in ferrous and non-ferrous materials. It features a 0.748-inch cutting diameter, a 1.3125-inch length of cut, and a 5-inch overall length. The 30-degree helix spiral flute geometry promotes efficient chip evacuation and smooth cutting action. Machinists and toolroom operators use this end mill in manual and CNC milling applications where center-cutting capability and right-hand cut direction are required.

The OSG 5823100 suits general-purpose milling in job shops, production environments, and toolroom settings. Its 0.75-inch shank diameter fits standard ER and end mill holders commonly found on vertical milling machines and machining centers. The double-end configuration provides two usable ends, extending tool life between changeovers. The uncoated finish makes this tool well-suited for applications where regrinding and reconditioning are part of the shop workflow. It is appropriate for slotting, profiling, and peripheral milling in steel, alloy steel, and similar workpiece materials.

Key Features

• M42 cobalt construction for improved heat and wear resistance over standard HSS
• Double-end design provides two cutting ends per tool
• Center-cutting capability allows plunge cuts and ramp entry
• 30-degree helix angle promotes chip evacuation in spiral flute configuration
• Right-hand cut and right-hand flute, compatible with standard spindle rotation
• Uncoated finish supports reconditioning and regrinding

Compatibility

Designed for use in standard end mill holders and collet chucks accepting a 0.75-inch shank diameter. Part of the OSG Series 582 cobalt end mill line.

Installation Notes

Installation is performed by qualified machinists following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended engagement depth in the holder and verify runout before cutting. Follow shop-specific feeds, speeds, and depth-of-cut parameters appropriate for the workpiece material and machine capability.
