Osg VGM7-0043 Corner Radius End Mill 3/8 in 7 Flute

Product Description

The OSG VGM7-0043 is a solid carbide corner radius end mill engineered for high-performance finishing operations on hard and difficult-to-machine materials. It features a 3/8-inch mill diameter, a 0.03-inch corner radius, and seven flutes in a close-pitch, spiral arrangement for improved chip evacuation and surface finish. The EXO coating provides thermal resistance and extended tool life when machining steel, stainless steel, cast iron, superalloys, and titanium. The single-end, right-hand cutting design with a straight cylindrical shank makes it compatible with standard toolholders. This tool is specified and installed by machinists and CNC operators in precision metalworking environments.

The VGM7-0043 is suited for finishing passes in demanding metalworking applications where tight tolerances and surface quality are critical. Its short-length geometry and 7-flute close-pitch configuration make it well-suited for profiling, contouring, and finishing in materials classified under ISO material groups P, M, K, S, and H. The variable index flute spacing reduces harmonic vibration during high-speed cuts. It is designed for use in vertical and horizontal machining centers with appropriate toolholders.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard material applications
• EXO coating for elevated thermal stability and extended cutting life
• 7-flute close-pitch design improves surface finish and material removal rate on finishing passes
• Variable index flute spacing reduces chatter and vibration during high-speed operation
• 0.03-inch corner radius protects cutting edge and reduces stress concentration at corners
• Right-hand flute direction and cutting action compatible with standard CNC spindle setups

Compatibility

Designed for use with standard toolholders. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium (ISO groups P, M, K, S, and H). Part of the OSG VGM7 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or carousel is powered down before changing tooling. Seat the straight cylindrical shank fully into the toolholder and torque the retention mechanism per the toolholder manufacturer's specifications. Verify runout with a dial indicator before beginning any cutting operation.
