Osg VG441-5011 Square End Mill 1/2 in 4 Flute Solid Carbide

Product Description

The OSG VG441-5011 is a solid carbide square end mill designed for high-performance milling operations in metalworking and machining environments. The tool measures 0.5 inches in diameter with a 2-inch length of cut, a 0.5-inch shank diameter, and a 4-inch overall length. It features four flutes ground in a spiral configuration at a 35-degree helix angle, with a TiAlN coating that extends tool life in ferrous and high-temperature alloy applications. A variable index design reduces harmonic vibration during aggressive cuts. This end mill is installed and operated by machinists and tool-and-die professionals working with CNC machining centers and manual mills.

The VG441-5011 is suited for slotting, profiling, and peripheral milling in ferrous metals, stainless steels, and similar materials where heat resistance and edge retention are critical. The centercutting geometry allows plunge entry, adding versatility to the tool's application range. Right-hand cut and right-hand flute configuration match standard CNC spindle rotation. The regular-length format makes it a practical choice for general-purpose work where extended reach is not required.

Key Features

• Solid carbide construction for rigidity and wear resistance
• TiAlN coating improves heat resistance and extends tool life in high-temperature alloys
• 35-degree spiral helix angle promotes efficient chip evacuation
• Variable index flute spacing reduces chatter and vibration
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute for standard spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-fit tool for CNC machining centers and manual mills accepting a 0.5-inch shank diameter, within the OSG VG441 series.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with CNC or manual milling equipment. Secure the shank fully in a collet or end mill holder to the manufacturer-specified engagement depth before operation. Power down and lock out the spindle before changing or inspecting the tool. Follow shop safety protocols and applicable OSHA machine guarding standards when operating milling equipment.
