Osg VGM6-0049 Corner Radius End Mill 3/8 in 6 Flute Carbide

Product Description

The OSG VGM6-0049 is a solid carbide corner radius end mill engineered for high-performance finishing operations in demanding materials. Part of the OSG VGM6 series, this single-end tool features a 3/8 inch diameter cutting edge with a 0.06 inch corner radius, six flutes in a right-hand spiral configuration, and a close pitch design with variable index geometry. The EXO coating provides enhanced surface hardness and heat resistance to extend tool life in abrasive cutting environments. With an overall length of 2.5 inches and a 3/4 inch length of cut, it is sized for short-reach finishing work in precision machining applications.

This end mill is designed for finishing operations on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is well suited for CNC machining centers and milling machines where tight tolerances and surface finish quality are critical. The straight-cylindrical shank mates directly with standard toolholders. The variable index flute spacing helps reduce chatter and vibration, making it a reliable choice for difficult-to-machine alloys in both job shop and production environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• EXO coating increases surface hardness and reduces heat buildup at the cutting edge
• Six-flute, close-pitch design provides superior surface finish on finishing passes
• Variable index geometry reduces harmonic chatter during high-feed milling
• 0.06 inch corner radius protects cutting edges and improves corner durability in pocketing and profiling operations
• Right-hand cut, right-hand flute spiral with medium helix angle for balanced chip evacuation

Compatibility

Designed for use with standard straight-bore toolholders. Rated for primary workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material codes P, M, K, S, H).

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine fully powered down and the spindle locked. Ensure the toolholder bore is clean and free of debris before seating the shank, and verify runout with a dial indicator before cutting. Follow the machine and toolholder manufacturer torque specifications for set screws or collet nuts. Review OSG cutting data recommendations for feeds, speeds, and depth of cut appropriate to the workpiece material before first use.
