Osg 464-5512 Square End Mill 0.5512 in 4 Flute Carbide

Product Description

The OSG 464-5512 is a solid carbide square end mill designed for precision material removal in metalworking and machining applications. With a 0.5512-inch (14.00 mm) mill diameter and a 2.2441-inch (57.00 mm) length of cut, this tool handles deep-slot and long-reach cutting tasks that shorter end mills cannot. The 4-flute, spiral-flute geometry with a 30-degree helix angle delivers efficient chip evacuation and a stable cutting action. Centercutting capability allows plunge cuts directly into workpiece material. This end mill is uncoated solid carbide, suited for machinists and tool-and-die professionals running CNC mills or manual vertical mills.

The OSG 464-5512 belongs to the Series 464 long-length end mill line, making it appropriate for applications that require extended reach into deep pockets, slots, or cavities. It is well suited for job shops, production machining environments, and toolroom work where a single-end, right-hand cut tool with right-hand fluting is the standard configuration. The long length-of-cut range of 2.0 inches and above positions this tool for passes that standard-length end mills cannot complete in a single setup.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• 4-flute spiral geometry with a 30-degree helix angle for efficient chip flow
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut, right-hand flute configuration standard for CNC and manual mill spindles
• Long-series length of cut (2.2441 inches) for deep pocket and slot work
• Uncoated finish suitable for use as-is or as a base for shop-applied coatings

Compatibility

Designed as an OEM-style solid carbide square end mill in the OSG Series 464 long-length line, compatible with standard end mill holders and collet chucks accepting a 14.00 mm (0.5512 inch) shank diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with end mill runout tolerances and proper holder torque procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank to the full recommended grip depth in the holder to minimize deflection during long-reach cuts. Verify spindle speed and feed rate settings against the material being cut before engaging the workpiece.
