Osg VGM6-0046 Square End Mill 3/8 in 6 Flute Solid Carbide

Product Description

The OSG VGM6-0046 is a 6-flute, solid carbide square end mill designed for high-performance milling in demanding metal-cutting applications. Built on OSG's VGM6 series platform, it features a 3/8-inch mill diameter, a 3/4-inch length of cut, and a 37-degree helix angle with a variable index flute spacing. The EXO coating improves wear resistance and heat dissipation, extending tool life in abrasive or hard materials. The micrograin carbide substrate provides the rigidity and edge retention needed for aggressive material removal at elevated feeds and speeds. This tool is installed by machinists and tool-and-die professionals in CNC milling operations.

This end mill is suited for slot milling, peripheral milling, and profiling operations on ferrous and non-ferrous workpiece materials. The stub-length configuration reduces overhang and improves rigidity, making it well-suited for applications where chatter control is a priority. The straight-cylindrical shank allows direct clamping in standard collet chucks, end mill holders, or shrink-fit tooling systems. Right-hand cutting direction and right-hand flute spiral are standard for conventional CNC vertical and horizontal machining center setups.

Key Features

• 6-flute configuration for improved surface finish and higher feed rates compared to 4-flute designs
• Variable index flute spacing reduces harmonic vibration and chatter during cut
• 37-degree helix angle balances axial cutting force and chip evacuation
• EXO coating provides elevated heat and wear resistance for extended tool life
• Micrograin solid carbide substrate delivers consistent edge sharpness and rigidity
• Stub-length geometry minimizes deflection in tight-tolerance milling applications

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for CNC machining centers accepting a 3/8-inch straight-cylindrical shank, compatible with standard collet chucks, end mill holders, and shrink-fit toolholders of the same bore size.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully powered down and the machine is in a safe state before loading or removing tooling. Verify collet or holder bore size matches the 3/8-inch shank diameter before clamping. Do not exceed the tool manufacturer's recommended cutting parameters for the workpiece material and coating type.
