Osg VGM5-1001 Square End Mill 1/8 in 5 Flute Carbide

Product Description

The OSG VGM5-1001 is a solid carbide square end mill designed for high-performance milling in demanding metalworking applications. Built on OSG's VGM5-LN series platform, it features a 1/8 inch mill diameter, a 5/32 inch length of cut, and five helical flutes with a 40-degree helix angle. The micrograin carbide substrate and EXO coating work together to extend tool life and maintain cutting edge integrity in difficult materials. This is a single-end, center-cutting tool with a variable index design for improved chip evacuation and reduced chatter. Shank diameter is 1/8 inch with a straight cylindrical profile.

This end mill is suited for precision slot milling, profiling, and finishing passes in ferrous and non-ferrous metals, hardened steels, and high-temperature alloys. The extended reach configuration makes it practical in setups where access depth is a factor. It is commonly used in CNC machining centers, toolroom applications, and production environments where tight tolerances and consistent surface finish are required. Machinists, tool and die makers, and CNC operators working on close-tolerance components will find this tool appropriate for both roughing passes in narrow slots and finish profiling work.

Key Features

• 1/8 inch mill diameter with 5/32 inch length of cut for small-feature work
• Five helical flutes with 40-degree helix angle for smooth chip flow
• EXO coating for improved wear resistance and heat management
• Micrograin solid carbide substrate for hardness and edge retention
• Variable index flute spacing reduces harmonic vibration during cutting
• Center-cutting design allows plunge entry and ramp milling

Compatibility

Designed as an OEM-style replacement or direct application tool within the OSG VGM5-LN series. Compatible with standard 1/8 inch collets, end mill holders, and straight-bore tool holders used on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Use a calibrated torque wrench with the appropriate collet nut wrench to secure the tool to manufacturer-recommended clamp specifications for the holder type. Inspect the cutting edges for chips or wear before each use, and verify runout with a dial indicator when critical tolerances are required.
