Osg VGM5-0161 Corner Radius End Mill 0.5in 5 Flute Solid Carbide

Product Description

The OSG VGM5-0161 is a solid carbide corner radius end mill designed for high-performance material removal across a range of demanding workpiece materials. Built on the VGM5 series platform, this single-end tool features a 0.5 inch mill diameter, a 0.01 inch corner radius, and five flutes with a high-helix, right-hand spiral configuration. It carries OSG EXO coating for extended tool life and heat resistance at elevated cutting speeds. The extra-long geometry — 2.5 inches length of cut and 5 inches overall length — suits deep-cavity and long-reach milling operations. Variable index spacing reduces harmonic chatter during both roughing and finishing passes. This tool is installed and run by machinists and CNC operators in precision machining environments.

The VGM5-0161 is suited to vertical and horizontal CNC machining centers handling steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material codes P, M, K, S, and H). Its center-cutting capability supports plunge entry. The extra-long length of cut makes it a practical choice for mold and die work, deep-pocket aerospace components, and structural part machining where standard-length tools lack reach. The straight-cylindrical shank mounts in a standard toolholder without special adapters.

Key Features

• 0.01 inch corner radius reduces stress concentration at the cutting edge and extends edge life in hardened materials
• EXO coating provides high-temperature wear resistance for dry and semi-dry cutting in steel and superalloys
• Variable index flute spacing minimizes chatter vibration during aggressive roughing cuts
• Five-flute design increases feed rate potential compared to four-flute configurations at equivalent chip loads
• Center-cutting geometry supports direct plunge entry without pre-drilled pilot holes
• Extra-long 2.5 inch length of cut accommodates deep-pocket and long-reach milling applications

Compatibility

Compatible with standard toolholders accepting a 0.5 inch straight-cylindrical shank. Shank diameter tolerance is h6. Mill diameter tolerance is 0.0000 to -0.0011 inches. Designed for use on CNC machining centers cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials.

Installation Notes

Installation and tool-change procedures should follow the toolholder manufacturer specifications and shop safety protocols — verify spindle is fully stopped and locked out before handling the tool. Seat the shank fully in the toolholder bore and torque the retention mechanism per the toolholder manufacturer's instructions. Inspect the cutting edge and corner radius for chipping or coating wear before each use, particularly after hard-material applications. Confirm correct cutting direction — this tool runs right-hand in a right-hand spindle rotation setup.
