Osg VGM5-0003 Square End Mill 1/8 in 5 Flute Solid Carbide

Product Description

The OSG VGM5-0003 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. Built on the VGM5 series platform, this single-end tool features a 1/8 inch cutting diameter, a 1/4 inch length of cut, and five helical flutes with a 40-degree helix angle. The variable index flute geometry reduces harmonic chatter during cuts, improving surface finish and tool life. An EXO coating provides enhanced lubricity and heat resistance, making this end mill well suited for extended runs in harder workpiece materials. Machinists and tool-and-die professionals install this type of tool in CNC machining centers and manual milling machines.

This end mill is intended for precision milling operations where tight tolerances and fine surface finishes are required. The stub-length configuration and 1/8 inch straight-cylindrical shank make it appropriate for applications with limited clearance or where rigidity is critical to part quality. Right-hand cutting direction suits standard CNC spindle configurations. It is applicable to slotting, profiling, and contouring operations in a shop or production environment.

Key Features

• 5-flute helical design with variable index for chatter reduction
• EXO coating for improved heat resistance and tool longevity
• 40-degree helix angle optimized for smooth chip evacuation
• Centercutting capability allows plunge entry into workpiece
• Micrograin solid carbide construction for rigidity and wear resistance
• Stub-length body with straight-cylindrical shank for maximum setup rigidity

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill compatible with CNC machining centers and manual mills accepting a 1/8 inch straight-cylindrical shank.

Installation Notes

Installation is performed by a machinist or toolroom professional using an appropriate collet or end mill holder rated for the 1/8 inch shank diameter. Verify tool runout with a dial indicator before starting a production run. Confirm spindle direction is set to right-hand rotation before engaging the cut. Follow the machine tool manufacturer guidelines for feed rate and spindle speed for the specific workpiece material being machined.
