Osg VGM5-0063 Square End Mill 1/4 in 5 Flute Carbide

Product Description

The OSG VGM5-0063 is a solid carbide square end mill designed for high-performance milling in metalworking and machining applications. With a 1/4 inch cutting diameter, five flutes, and a 40-degree helix angle, this end mill delivers efficient chip evacuation and smooth cutting action on ferrous and non-ferrous materials. The EXO finish enhances wear resistance and extends tool life in demanding cutting environments. The variable index geometry reduces chatter and vibration, improving surface finish quality. This tool is installed by machinists and CNC operators in job shop, production, and toolroom settings.

This end mill is suited for slotting, peripheral milling, and profiling operations on CNC machining centers and manual mills. The 1/4 inch shank diameter matches standard collet and end mill holder sizes common in light to medium-duty milling setups. With a 1 inch length of cut and 3 inch overall length, it is configured for standard-reach applications where rigidity and deflection control are priorities. Micrograin carbide construction supports use in higher-speed cutting programs where tool stability is critical.

Key Features

• 5-flute design improves feed rates and surface finish compared to standard 4-flute geometry
• 40-degree helix angle promotes efficient chip flow and reduces cutting forces
• EXO coating enhances heat resistance and extends tool life in abrasive materials
• Variable index flute spacing reduces harmonic chatter during aggressive cuts
• Centercutting capability allows plunge milling entries
• Micrograin solid carbide substrate provides hardness and edge retention

Compatibility

Designed as an OEM-style replacement for standard 1/4 inch shank square end mill applications in CNC and manual milling operations requiring a 5-flute, single-end, right-hand cut tool with straight-cylindrical shank.

Installation Notes

Installation is performed by machinists using a collet chuck or end mill holder sized for a 1/4 inch straight-cylindrical shank. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Tighten the tool holder to the manufacturer-specified torque using a torque wrench appropriate for the holder type. Verify runout with a dial indicator after installation to confirm proper seating before beginning a cut program.
