Osg VGM5-0119 Corner Radius End Mill 3/8 in 5 Flute

Product Description

The OSG VGM5-0119 is a solid carbide corner radius end mill designed for high-performance metal removal in demanding machining environments. It features a 3/8 inch cutting diameter, a 0.06 inch corner radius, and five flutes arranged in a right-hand spiral configuration with a variable index for reduced chatter and improved surface finish. The cutting length is 1.5 inches with a 4 inch overall length and a 3/8 inch straight cylindrical shank. OSG's proprietary EXO coating improves wear resistance and thermal stability, making this tool well suited for aggressive cuts in hard and abrasive workpiece materials. It is used by machinists and tool-and-die professionals in CNC milling operations.

The VGM5-0119 is rated for roughing and finishing operations across a broad range of primary workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The centercutting geometry allows direct plunge entry, and the high-helix flute design promotes efficient chip evacuation. This tool is intended for use with a standard toolholder with an h6 shank diameter tolerance for a secure, repeatable fit in close-tolerance setups.

Key Features

• 0.06 inch corner radius reduces stress concentration and extends tool life at the cutting edge
• EXO proprietary coating provides enhanced hardness and heat resistance for ferrous and superalloy cutting
• 5-flute, right-hand spiral geometry supports both roughing and finishing in a single tool
• Variable index flute spacing minimizes harmonic vibration during high-speed milling
• Centercutting design enables plunge milling without a pre-drilled pilot hole
• Long flute length of 1.5 inches accommodates deeper axial cuts in a single pass

Compatibility

Designed for use with standard CNC toolholders accepting a 3/8 inch straight cylindrical shank with h6 tolerance. Rated for steel, stainless steel, cast iron, superalloys, titanium, and hard materials per OSG Series VGM5 application guidelines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols and machine tool manufacturer guidelines. Ensure the spindle is fully stopped and locked out before changing tooling. Verify toolholder runout with a dial indicator before committing to finish cuts. Do not exceed the recommended axial and radial depth of cut for the workpiece material being machined.
