Osg VGM5-0093 Square End Mill 5/16in 5 Flute Carbide Exo

Product Description

The OSG VGM5-0093 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 5/16 inch (0.3125 inch) mill diameter and a 1-1/4 inch length of cut, this tool is built for high-performance material removal in a compact form factor. The 5-flute helical geometry combined with a 40-degree helix angle promotes smooth chip evacuation and improved surface finish. The proprietary EXO coating extends tool life and reduces heat buildup during aggressive cutting operations. This tool is installed and operated by machinists and CNC tooling professionals working in production and job shop environments.

This end mill is suited for finish and semi-finish milling of ferrous and non-ferrous materials in vertical machining centers and CNC milling machines. The single-end, right-hand cutting configuration with a straight cylindrical shank fits standard collet and end mill holder systems. The micrograin carbide substrate and variable index geometry make this tool appropriate for demanding side milling, slotting, and profiling passes at tighter tolerances. It is used in industrial, aerospace, automotive, and general precision machining settings.

Key Features

• 5-flute helical design with 40-degree helix angle for efficient chip evacuation and reduced chatter
• EXO coating for extended tool life and thermal resistance during high-speed cutting
• Micrograin solid carbide substrate for hardness and edge retention
• Variable index flute spacing to minimize vibration and improve surface finish
• Center-cutting capable for plunge entry into workpiece
• Right-hand cut and right-hand flute direction for standard spindle compatibility

Compatibility

Designed as an OEM-style replacement and production tooling option for CNC milling machines and machining centers accepting a 5/16 inch straight cylindrical shank end mill holder or collet system.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully powered down and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended engagement depth per the machine and holder manufacturer guidelines. Verify runout with a dial indicator before commencing the first cut.
