Osg VGM6-0078 Corner Radius End Mill 1/2 in 6 Flute Carbide

Product Description

The OSG VGM6-0078 is a solid carbide corner radius end mill designed for high-performance finishing operations in demanding metalworking applications. Built on OSG's VGM6 series platform, this single-end mill features a 0.5 inch diameter, a 1.125 inch corner radius, 6 flutes with a close pitch arrangement, and a 37-degree medium helix. The EXO proprietary coating enhances wear resistance and thermal stability during aggressive cuts. Right-hand cutting and right-hand flute direction suit standard CNC machining center setups. This tool is intended for use with a standard toolholder and a straight-cylindrical shank.

The VGM6-0078 is rated for finishing cuts across a broad range of primary workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The corner radius geometry — 0.125 inch radius — reduces stress concentration at the cutting edge and extends tool life versus a sharp-corner end mill in difficult alloys. The 1.25 inch length of cut and 3 inch overall length make this a standard-reach tool suited for typical pocket, slot, and contour finishing operations on machining centers in production and job-shop environments.

Key Features

• 0.5 inch mill diameter with mill diameter tolerance of 0.0000 to -0.0011 inches for precision fit
• 6-flute close-pitch configuration optimized for finishing material removal
• 0.125 inch corner radius reduces edge chipping in hard and abrasive materials
• EXO coating provides enhanced heat and wear resistance for extended tool life
• Variable index flute spacing reduces harmonic chatter during high-speed passes
• Compatible with steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO P, M, K, S, H classifications)

Compatibility

Designed for use with standard straight-bore toolholders. Suitable for machining steel, stainless steel, cast iron, superalloys and titanium, and hard materials as designated by ISO material codes P, M, K, S, and H. Part of the OSG VGM6 series.

Installation Notes

Installation is performed by a machinist or CNC setup technician using a compatible toolholder with a straight-cylindrical bore. Ensure the machine spindle is fully stopped and the tool changer is in a safe state before inserting or removing the end mill. Confirm runout with a dial indicator after seating to stay within the stated diameter tolerance. Follow shop-standard speeds and feeds for carbide tooling in the target workpiece material.
