Osg 82002021 Square End Mill 0.625 in 4 Flute Solid Carbide

Product Description

The OSG 82002021 is a solid carbide square end mill from the OSG Series 8200 line, designed for precision milling in metalworking and machining applications. It features a 0.625 inch mill diameter, a 1.25 inch length of cut, and a 3.5 inch overall length with a 0.625 inch shank diameter. The tool carries OSG's Duarise coating and is manufactured from micrograin carbide, giving it strong wear resistance and edge retention. Variable helix and variable index geometry reduce harmonics and chatter during cutting. Centercutting capability allows both plunge and peripheral milling. This end mill is intended for use by machinists and CNC operators in professional shop environments.

The OSG 82002021 is suited for milling operations on steel, stainless steel, cast iron, and similar ferrous materials, as well as non-ferrous alloys where a coated carbide tool is appropriate. With its straight flute design, right hand cut, and right hand flute orientation, it performs well in standard vertical and horizontal milling setups. The regular-length profile makes it a practical choice for general-purpose slotting, profiling, and contouring operations on CNC machining centers and manual mills alike.

Key Features

• Solid micrograin carbide construction for durability and edge retention
• Duarise coating provides enhanced wear resistance and heat management
• Variable helix and variable index geometry reduce chatter and vibration
• Centercutting design allows direct plunge entry into workpiece
• Right hand cut with straight flute and right hand flute direction
• 4-flute configuration balances chip evacuation with surface finish

Compatibility

Designed as an OSG Series 8200 replacement or direct-use solid carbide square end mill for standard 0.625 inch shank tool holders used in CNC and manual milling applications.

Installation Notes

Installation of end mills should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Use a properly sized collet or end mill holder that matches the 0.625 inch shank diameter to ensure secure, concentric clamping. Follow the tool manufacturer's recommended speeds and feeds for the specific workpiece material to avoid premature tool wear or breakage.
