Osg VGM5-2130 Variable Geometry End Mill 1/2 Inch 5 Flute

Product Description

The OSG VGM5-2130 is a 5-flute solid carbide end mill from the VGM5-NIK series, designed for high-performance milling in demanding machining environments. It features a variable index geometry combined with a chipbreaker (nicked) flute profile, which breaks up long chips and reduces cutting forces during aggressive material removal passes. The 1/2-inch mill diameter pairs with a 1/2-inch straight-cylindrical shank for direct fit in standard collets and end mill holders. Applied EXO coating enhances surface hardness and heat resistance. This tool is installed and operated by CNC machinists, tool-and-die professionals, and precision machining technicians.

The VGM5-2130 is suited for milling ferrous and non-ferrous metals in both roughing and semi-finishing operations on vertical and horizontal machining centers. The chipbreaker geometry makes it particularly effective in deep-pocket and full-width slot milling where chip evacuation is critical. The 1-inch length of cut and regular-length body fit standard tool-length setups without requiring extended-reach adapters. The 40-degree helix angle promotes smooth cutting action and stable tool engagement across a range of workpiece materials.

Key Features

• Chipbreaker (nicked) flute profile breaks chips and reduces cutting forces in aggressive passes
• Variable index geometry minimizes chatter and vibration during high-feed milling
• EXO coating provides elevated heat resistance and extended tool life
• 5-flute configuration increases feed rate capability compared to 4-flute designs
• 40-degree helix angle promotes smooth chip flow and stable engagement
• Centercutting design allows plunge entry without a pre-drilled hole

Compatibility

Designed as an OEM-style replacement within the OSG VGM5-NIK series. Compatible with standard 1/2-inch bore collets, shrink-fit holders, and end mill holders used on CNC vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Secure the shank fully within the holder to the recommended gauge length and verify runout with a dial indicator before cutting. Confirm spindle and coolant systems are off and the machine is in a safe state before tool changes. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut.
