Osg 82011021 Square End Mill 0.75in 5 Flute Solid Carbide

Product Description

The OSG 82011021 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.75 inch diameter, 2.25 inch length of cut, and 5.5 inch overall length, this end mill handles deep-cavity and peripheral milling where rigidity and edge retention matter. The 5-flute geometry increases chip load capacity and improves surface finish compared to standard 4-flute tools. A Duarise coating reduces friction and extends tool life in demanding cutting conditions. Micrograin carbide substrate provides the hardness and toughness needed for high-speed machining applications. This tool is installed and operated by CNC machinists and tool-and-die professionals.

This end mill is suited for use in vertical and horizontal machining centers where a 0.75 inch shank is required. The right-hand cut, right-hand flute configuration is the standard orientation for conventional and climb milling on CNC equipment. The variable helix design helps reduce chatter and harmonic vibration during long-reach or deep-slot cuts. Centercutting capability allows for direct plunge entry as well as ramping and helical interpolation. Applications include slot milling, profile milling, and contour work in mold and die, aerospace, and general precision machining environments.

Key Features

• 0.75 inch diameter with 2.25 inch length of cut for deep-reach applications
• 5-flute design increases material removal rate and improves surface finish
• Duarise coating reduces friction and extends cutting edge life
• Variable helix geometry minimizes chatter and vibration
• Centercutting — capable of plunge, ramp, and helical entry
• Micrograin solid carbide substrate for hardness and wear resistance

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 0.75 inch straight shank end mill.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank in a collet or end mill holder rated for the shank diameter and ensure runout is within acceptable tolerance before operation. Verify spindle speed and feed rate parameters are set according to the material being cut and the tool manufacturer guidelines. Never exceed the rated length of cut depth in a single pass without appropriate feed adjustments.
