Osg VGM6-0074 Corner Radius End Mill 1/2 in 6 Flute

Product Description

The OSG VGM6-0074 is a solid carbide corner radius end mill designed for high-performance finishing operations in demanding metalworking applications. It features a 1/2 inch cutting diameter, a 0.03 inch corner radius, and 6 flutes with a variable index configuration that reduces harmonic chatter during cuts. The EXO coating provides enhanced wear resistance and heat protection, extending tool life in abrasive and hard materials. At 3 inches overall length with a 1-1/4 inch length of cut, this single-end mill is suited for CNC machining centers and milling operations where consistent edge geometry and surface finish are critical.

This end mill is intended for finishing passes on ferrous and exotic workpiece materials in both job shop and production environments. Its close pitch, right-hand spiral flute geometry and straight cylindrical shank make it compatible with standard toolholders used in vertical and horizontal machining centers. The VGM6-0074 is a strong choice for machinists working on tight-tolerance components where corner integrity and surface quality are priorities.

Key Features

• 0.03 inch corner radius protects edge geometry and improves surface finish at part corners
• 6-flute, close-pitch design increases feed rates and improves surface finish in finishing applications
• Variable index flute spacing reduces vibration and chatter without variable helix
• EXO proprietary coating enhances heat and wear resistance for extended tool life
• Solid carbide construction provides rigidity and dimensional stability under cutting loads
• Right-hand cut, right-hand flute spiral with straight cylindrical shank for broad toolholder compatibility

Compatibility

Designed for use with standard cylindrical-bore toolholders. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials as designated by material codes P, M, K, S, and H.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and the machine in a safe, de-energized state. Ensure the straight shank is fully seated and properly torqued in the toolholder collet or chuck per the toolholder manufacturer specifications before operation. Confirm runout is within acceptable tolerance before beginning a finishing pass, as excessive runout will degrade surface finish and accelerate edge wear. Follow applicable shop safety standards and machine guarding requirements during setup and operation.
