Osg VGM5-0090 Corner Radius End Mill 5/16 in 5 Flute Carbide

Product Description

The OSG VGM5-0090 is a single-end corner radius end mill from OSG's VGM5 series, designed for demanding material removal in ferrous and hard-to-machine workpieces. Built from solid carbide and finished with OSG's proprietary EXO coating, this tool handles both roughing and finishing operations in a single setup. It measures 5/16 inches in diameter with a 0.02-inch corner radius, 15/16 inches length of cut, and 3 inches overall length. The 5-flute geometry with variable index and high helix style delivers smooth chip evacuation and reduced chatter, making it well suited for high-feed-rate applications on CNC machining centers.

This end mill is built for use in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Its straight-cylindrical shank seats directly into standard toolholders, and the center-cutting design allows for plunge entry. The VGM5 series targets shops running tight-tolerance work where surface finish and tool life both matter. Typical applications include profile milling, slotting, and corner-blending passes on aerospace, medical, and general precision machined components.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• EXO coating reduces friction and extends tool life in steel, stainless, and superalloy cuts
• 5-flute, variable-index design minimizes harmonic vibration and supports high material removal rates
• 0.02-inch corner radius protects the cutting edge and improves surface finish at part corners
• Center-cutting capable — supports direct plunge entry without a pilot hole
• Right-hand cut, right-hand flute spiral with high helix for efficient chip evacuation

Compatibility

Designed for use with standard straight-bore toolholders accepting a 5/16-inch cylindrical shank. Suitable for CNC vertical and horizontal machining centers running 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 tooling technician. Secure the shank fully within the toolholder to the recommended gauge-line depth before tightening — never grip on the fluted section. Verify runout with a dial indicator after assembly; excessive runout accelerates edge wear and reduces surface finish quality. Consult your machine tool and toolholder manufacturer's specifications for clamping torque and balance requirements before use at high spindle speeds.
