Osg VGM5-0095 Square End Mill 3/8 in 5 Flute Carbide Exo

Product Description

The OSG VGM5-0095 is a solid carbide square end mill designed for precision material removal in professional machining applications. Built on OSG's VGM5 series platform, this single-end tool features a 3/8-inch mill diameter, five helical flutes with a 40-degree helix angle, and a variable index geometry that reduces harmonic vibration during cutting. The EXO coating improves surface hardness and heat resistance, extending tool life in demanding cutting conditions. At 2 inches overall length with a 9/16-inch length of cut, this is a stub-length configuration suited for rigid, close-tolerance work. Machinists and CNC operators in job shops, aerospace, and general manufacturing rely on this geometry for finishing and semi-finishing passes.

This end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills where a 3/8-inch straight-cylindrical shank and right-hand cutting direction are required. The micrograin carbide substrate and EXO coating make it well-suited for cutting steels, stainless steels, and other ferrous alloys at elevated speeds and feeds. The centercutting capability allows plunge entry, adding versatility in slotting, pocketing, and profiling operations.

Key Features

• Solid micrograin carbide substrate for rigidity and wear resistance
• EXO coating for elevated heat resistance and extended tool life
• 5-flute helical design with 40-degree helix angle for smooth chip evacuation
• Variable index flute spacing reduces chatter and harmonic vibration
• Centercutting geometry supports plunge, slot, pocket, and profile operations
• Stub-length configuration (9/16-inch LOC) maximizes rigidity at the cutting edge

Compatibility

Designed for use in CNC and manual milling machines accepting a 3/8-inch straight-cylindrical shank, right-hand spindle rotation, with standard ER or end mill collet toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended collet grip depth and torque the collet nut to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a production cut.
