Osg VGM5-0149 Corner Radius End Mill 5 Flute Solid Carbide

Product Description

The OSG VGM5-0149 is a single-end corner radius end mill from the VGM5 series, designed for demanding material removal in both roughing and finishing operations. Built from solid carbide and coated with OSG EXO coating, this tool delivers thermal and wear resistance in high-speed machining environments. It features a 0.5-inch diameter, a 1.5-inch length of cut, and a 0.01-inch corner radius that reduces edge chipping and extends tool life in hard and abrasive materials. The 5-flute, right-hand spiral geometry with variable index promotes smooth chip evacuation and reduced chatter. Licensed machinists and CNC operators working in production or job-shop settings are the primary users.

The VGM5-0149 is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and other hard materials. Its high helix angle and normal pitch make it effective across a broad range of cutting conditions, from slot milling to peripheral finishing passes. The center-cutting capability allows plunge entry where the application requires it. Typical use cases include die and mold work, aerospace component machining, and general precision milling on CNC vertical and horizontal machining centers using a standard straight-shank toolholder.

Key Features

• Solid carbide construction with EXO coating for heat and wear resistance in hard materials
• 5-flute, right-hand spiral geometry with variable index for reduced harmonics and chatter
• 0.01-inch corner radius for edge strength and reduced chipping at the cutting corners
• Center-cutting design allows direct plunge entry
• Straight-cylindrical shank with h6 tolerance for consistent toolholder fit and runout control
• Rated for steel, stainless steel, cast iron, superalloys, titanium, and hard materials

Compatibility

Designed for use with standard straight-shank toolholders on CNC machining centers. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material codes P, M, K, S, H).

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the straight-cylindrical shank fully into the toolholder and verify runout before beginning a cut. Follow the machine tool manufacturer and toolholder manufacturer torque specifications when clamping.
