Osg VGM5-0013 Square End Mill 1/8 in 5 Flute Carbide Exo

Product Description

The OSG VGM5-0013 is a solid carbide square end mill designed for precision milling in demanding machining environments. Part of the OSG VGM5 series, this single-end tool features a 1/8 inch diameter cutting head with a 5/8 inch length of cut and five helical flutes ground from micrograin carbide stock. The EXO coating provides enhanced wear resistance and thermal stability during high-speed cutting operations. A 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. The variable index flute spacing helps suppress chatter and vibration, improving surface finish and tool life in challenging materials.

This end mill is suited for close-tolerance milling operations in ferrous and non-ferrous materials where a small-diameter tool is required. Typical applications include slot milling, profiling, and finishing passes in die and mold work, aerospace components, and precision mechanical parts. The straight cylindrical shank measures 1/8 inch in diameter, fitting standard ER collet chucks and precision toolholders. The long-length designation and 2.25 inch overall length allow access to deeper features without excessive tool stick-out.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard materials
• EXO coating for improved thermal and abrasion resistance at elevated cutting speeds
• Five helical flutes for high metal removal rates in small-diameter applications
• 40-degree helix angle promotes efficient chip flow and reduced cutting pressure
• Variable index flute spacing reduces harmonic chatter for improved surface finish
• Center-cutting geometry allows plunge entry into workpiece material

Compatibility

Designed for use in standard ER collet systems and precision toolholders accepting a 1/8 inch straight cylindrical shank. Suitable as an OEM-style replacement or direct selection within the OSG VGM5 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or toolholder and torque the retention nut to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates wear and can cause breakage in small-diameter carbide tools.
