Osg VGM5-0146 Corner Radius End Mill 0.5in 5 Flute

Product Description

The OSG VGM5-0146 is a solid carbide corner radius end mill from the VGM5 series, designed for high-performance material removal in demanding machining applications. The tool features a 0.5 inch mill diameter, a 0.12 inch corner radius, and five flutes with a right-hand spiral and right-hand cutting direction. A variable index geometry reduces chatter and vibration during aggressive cuts. The EXO coating provides enhanced wear resistance and heat management, extending tool life across a wide range of workpiece materials. At 3 inches overall length with a 1.25 inch length of cut, this is a single-end, straight-shank end mill suited for CNC machining centers and compatible toolholders.

This end mill is rated for use on steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material codes P, M, K, S, and H. It is capable of both roughing and finishing operations in a single tool, making it a practical choice for shops running tight schedules on difficult workpiece materials. The center-cutting design allows plunge entry, and the normal pitch with high-helix geometry supports chip evacuation in deep-pocket and slotting applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and exotic materials
• EXO coating for elevated-temperature performance and extended tool life
• Variable index flute spacing reduces harmonic vibration during heavy cuts
• Center-cutting capable — supports ramp, plunge, and interpolated entry
• Rated for roughing and finishing operations across steel, stainless, cast iron, superalloys, titanium, and hard materials
• Straight-cylindrical shank with h6 shank diameter tolerance for secure toolholder seating

Compatibility

Designed for use with standard CNC toolholders accepting a 0.5 inch straight-cylindrical shank. Suitable for machining centers running steel, stainless steel, cast iron, superalloys, titanium, and hard materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the toolholder bore is clean and free of debris before seating the shank, and verify runout with a dial indicator after clamping. Power down and lock out the spindle before any tool change. Follow the machine tool manufacturer's recommended clamping torque for the toolholder style in use.
