Osg 37420000 Square End Mill 0.1181 in 4 Flute Solid Carbide

Product Description

The OSG 37420000 is a solid carbide square end mill designed for precision milling operations across a range of ferrous and non-ferrous materials. With a 0.1181-inch (3.00 mm) cutting diameter, four flutes, and a 30-degree helix angle, this tool delivers efficient chip evacuation and a smooth surface finish. The WXL finish coating enhances wear resistance and thermal protection, extending tool life in demanding cutting conditions. The centercutting geometry allows plunge entry, giving machinists flexibility in pocketing, slotting, and profiling applications. It is intended for use by CNC machinists and tool-and-die professionals.

This end mill is suited for high-precision CNC milling in job shop, production, and tool room environments. The 0.1181-inch diameter makes it well-suited for fine detail work, small-feature pocketing, and tight-tolerance slot milling. With a length of cut of 0.4724 inches (12.00 mm) and a 6.00 mm shank diameter, it fits standard collets and end mill holders on vertical and horizontal machining centers. The right-hand cut and right-hand flute configuration is the standard orientation for conventional CNC milling spindles.

Key Features

• 0.1181-inch (3.00 mm) cutting diameter for small-feature precision milling
• Solid carbide construction for rigidity and extended wear life
• WXL finish coating for thermal and abrasion resistance
• 30-degree helix angle promotes efficient chip evacuation
• Centercutting design enables direct plunge entry
• Four flutes for improved finish quality and feed rate capability

Compatibility

Designed as a standard single-end square end mill with a 6.00 mm shank diameter, compatible with collet chucks and end mill holders sized for 6 mm shanks on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Secure the shank fully within the collet or holder to the recommended engagement depth before torquing. Verify spindle speed and feed rate settings against the tool manufacturer guidelines for the specific workpiece material before beginning a cut. Inspect the cutting edges for chipping or wear before each use and replace the tool if damage is observed.
