Osg VGM5-0153 Corner Radius End Mill 5 Flute Carbide

Product Description

The OSG VGM5-0153 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining applications. It features a 0.5-inch diameter, a 1.5-inch length of cut, and a 0.12-inch corner radius that reduces stress concentrations and extends tool life in interrupted and continuous cuts. With five flutes and a high-helix spiral configuration, the VGM5-0153 supports both roughing and finishing operations in a single tool path. The EXO coating provides elevated heat and wear resistance. This end mill is intended for use by machinists and CNC operators working in tool rooms, job shops, and production environments.

The VGM5-0153 is engineered for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Its variable index geometry reduces harmonic chatter, making it well suited for high-speed and high-feed strategies. The straight cylindrical shank fits standard toolholders. With a 4-inch overall length and 0.5-inch shank diameter, it fits a wide range of milling setups on vertical and horizontal machining centers. It is a single-end tool rated for right-hand cutting and right-hand flute direction.

Key Features

• 0.12-inch corner radius reduces tool stress and improves surface finish at part edges
• Five-flute design supports higher feed rates compared to standard four-flute geometry
• EXO coating improves wear resistance and thermal stability in ferrous and hard-material cutting
• Variable index spacing reduces vibration and chatter during aggressive cuts
• Center-cutting capability allows plunge entry without a pre-drilled pilot hole
• Compatible with standard straight-cylindrical toolholders at 0.5-inch shank diameter

Compatibility

Designed for use with standard straight-cylindrical toolholders. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Part of the OSG VGM5 series.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine spindle fully stopped and the control in a safe state. Confirm toolholder bore tolerance matches the shank diameter tolerance specification before securing. Verify runout with a dial indicator after installation and before cutting. Follow the machine manufacturer and OSG series guidelines for recommended speeds, feeds, and depth-of-cut parameters for the target workpiece material.
