Osg VG446-5002 Corner Radius End Mill 0.5in 4 Flute Tialn

Product Description

The OSG VG446-5002 is a solid carbide corner radius end mill engineered for demanding material removal in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It runs a 0.5 inch diameter with a 0.12 inch corner radius, four flutes, and a TiAlN PVD coating that holds up under high heat and abrasive cutting conditions. The 4 inch overall length and extended reach design give machinists access to deeper features without a tool change. Centercutting geometry allows plunge entry. This tool is suited for both roughing and finishing operations on CNC mills and machining centers.

The VG446-5002 fits production and job shop environments where multi-material versatility and long tool life matter. It is well-matched for mold and die work, aerospace component machining, and general precision part manufacture where corner radii are required to reduce stress concentrations. The Weldon flat shank seats securely in compatible toolholders. The 5/8 inch length of cut handles typical depth-of-cut requirements for its diameter class, and the 2.25 inch reach length supports work in pockets and recessed features.

Key Features

• TiAlN PVD coating for heat resistance and extended tool life in hard and abrasive materials
• 0.12 inch corner radius reduces stress risers and improves surface finish at part edges
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Variable index flute spacing reduces chatter and vibration during aggressive cuts
• Weldon flat shank provides positive anti-pullout engagement in toolholders
• Extended reach geometry at 2.25 inches reach length for deep pocket and cavity access

Compatibility

Designed for use with standard Weldon flat toolholders accepting a 0.5 inch shank. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials as identified in the OSG VG446 series application guidelines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the toolholder is clean and free of chips before seating the end mill. Torque the Weldon flat set screw against the flat on the shank to prevent pullout during cutting. Verify runout after installation and confirm cutting parameters are appropriate for the workpiece material and machine rigidity before beginning a cut.
