Osg VGM5-0154 Corner Radius End Mill 0.5in 5 Flute Carbide

Product Description

The OSG VGM5-0154 is a solid carbide corner radius end mill designed for demanding metal removal in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It carries a 0.5-inch mill diameter with a 0.125-inch corner radius and features 5 flutes in a right-hand spiral configuration. The EXO coating provides elevated wear resistance and thermal protection suited to high-productivity roughing and finishing operations. With a 1.5-inch length of cut and 4-inch overall length, this tool is sized for standard-depth peripheral and slot milling on CNC machining centers and manual mills using a straight-cylindrical toolholder.

This end mill is built for professionals running ferrous and hard-material applications where edge stability and surface finish are critical. The variable index geometry reduces harmonic chatter during aggressive cuts, and the centercutting design allows plunge entry. It is a single-end tool intended for use in tight-tolerance production and job-shop environments across aerospace, toolroom, and general machining applications. The 0.5-inch shank fits standard ER and side-lock toolholders without adapter sleeves.

Key Features

• Solid carbide construction for rigidity and heat resistance in hard materials
• EXO coating for extended tool life in steel, stainless, and superalloy cuts
• 5-flute variable index design reduces chatter and improves surface finish
• 0.125-inch corner radius protects the cutting edge and improves workpiece corner geometry
• Centercutting geometry enables plunge milling without a pilot hole
• Right-hand flute direction and right-hand cutting compatible with standard CNC spindle rotation

Compatibility

Designed for use with standard straight-cylindrical toolholders. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Part of the OSG VGM5 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle before changing tooling. Seat the shank fully into the toolholder to the recommended gauge-line depth and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear and degrades surface finish on corner radius tools.
