Osg VGM5-1059 Square End Mill 3/8 in 5 Flute Carbide

Product Description

The OSG VGM5-1059 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built on the VGM5-LN series platform, it features a 3/8 inch diameter cutting head with five helical flutes and a 40-degree helix angle. The variable index flute geometry reduces harmonic vibration during high-speed cuts, improving surface finish and tool life. An EXO coating adds thermal and wear resistance, making this end mill well-suited for demanding ferrous and non-ferrous materials. Micrograin carbide construction provides the hardness and edge retention required for consistent performance in production environments.

This end mill is intended for use by machinists and tooling professionals in CNC milling centers, vertical mills, and machining cells requiring tight tolerances and fine surface finishes. The 15/32 inch length of cut and 4 inch overall length make it appropriate for standard-depth slotting, profiling, and peripheral milling. The straight cylindrical shank seats directly in ER collet chucks, end mill holders, or shrink-fit tooling systems. It is configured as a single-end, right-hand cutting, right-hand flute tool suitable for conventional and climb milling strategies.

Key Features

• Solid micrograin carbide construction for hardness and edge retention
• EXO coating provides thermal resistance and extended tool life
• Five helical flutes with variable index geometry to reduce vibration
• 40-degree helix angle optimized for chip evacuation and surface finish
• Center-cutting design allows plunge entry into workpiece
• Extended reach configuration for accessing deeper features

Compatibility

Designed as an OEM-style replacement and standard tooling option within the OSG VGM5-LN series, compatible with any 3/8 inch straight-shank collet or end mill holder system.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the holder and torque the retention mechanism per the holder manufacturer specification. Inspect the cutting edges for chips or damage before each use, and confirm runout is within acceptable limits before engaging the workpiece.
