Osg VGM5-0009 Square End Mill 1/8 in 5 Flute Solid Carbide

Product Description

The OSG VGM5-0009 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 1/8 inch cutting diameter and a 5-flute helical geometry with a 40-degree helix angle, providing excellent chip evacuation and surface finish in demanding cutting conditions. The EXO coating increases surface hardness and heat resistance, extending tool life in high-speed applications. The variable index flute spacing reduces chatter and vibration during cutting. This tool is intended for use by machinists and tooling professionals in CNC machining centers and manual milling equipment.

This end mill is suited for finish milling, slotting, and profiling operations in metals and engineered materials. The single-end, center-cutting design allows plunge entry as well as peripheral and slot cutting. The straight cylindrical shank measures 1/8 inch in diameter, matching the cutting diameter for easy tool holder compatibility. With a 1/2 inch length of cut and a 2-1/4 inch overall length, it fits standard collet chucks and end mill holders used in production and job-shop environments.

Key Features

• 5-flute helical geometry with 40-degree helix angle for efficient chip removal and smooth finish
• EXO coating for improved wear resistance and heat management at elevated cutting speeds
• Variable index flute spacing reduces vibration and chatter during aggressive cuts
• Center-cutting single-end design supports plunge, slot, and profile milling
• Micrograin solid carbide construction for rigidity and edge retention
• Right-hand cut and right-hand flute direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct tooling selection for 1/8 inch straight cylindrical shank collet chucks and end mill holders used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the milling machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the collet or tool holder to the recommended gauge-line depth before tightening. Verify runout with a dial indicator after clamping to confirm concentricity before beginning any cut.
