Osg 82002621 Square End Mill 3/4 Inch 4 Flute Solid Carbide

Product Description

The OSG 82002621 is a solid carbide square end mill designed for precise milling operations in metal fabrication and machining applications. Built to Series 8200 standards, it features a 3/4-inch cutting diameter, a 1-1/2-inch length of cut, and a 4-inch overall length. The variable helix geometry and variable index spacing reduce harmonic vibration during cutting, improving surface finish and tool life. Four flutes provide efficient chip evacuation. The Duarise finish enhances wear resistance. This tool is used by machinists and CNC operators working in job shops, tool rooms, and production environments.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The straight flute configuration and centercutting capability allow plunge entry as well as lateral passes. The right-hand cut and right-hand flute orientation are standard for conventional CNC machining centers. A 3/4-inch shank diameter ensures secure tool holding in standard ER or side-lock collet chucks. It is well-matched to full-depth roughing and finishing passes where vibration control is a priority.

Key Features

• Variable helix and variable index geometry reduces chatter and vibration during aggressive cuts
• Solid carbide construction provides rigidity and wear resistance versus HSS tooling
• Duarise finish improves surface hardness and lubricity at the cutting edge
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Four-flute straight configuration balances chip clearance with cutting contact
• Right-hand cut and right-hand flute orientation for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 3/4-inch tool holders on CNC machining centers and manual mills accepting a 3/4-inch shank.

Installation Notes

Installation and tool changes must be performed with the spindle fully stopped and the machine in a safe, de-energized state. Secure the shank to the specified clamping torque for the tool holder type in use, referencing the tool holder manufacturer guidelines. Inspect the cutting edges and shank for chips or runout before each use. Tool selection and feeds and speeds should be verified against the workpiece material and machine capability before cutting.
