Osg VGM5-1036 Corner Radius End Mill 1/4 in 5 Flute Carbide

Product Description

The OSG VGM5-1036 is a solid carbide corner radius end mill from the VGM5-LN series, designed for high-performance material removal in demanding machining applications. It features a 1/4 inch diameter with a 0.06 inch corner radius and five flutes arranged in a variable index, right-hand spiral configuration. The EXO coating provides enhanced wear resistance and thermal protection at the cutting edge. With a short-length geometry and extended reach shank, this end mill is suited for both roughing and finishing passes in a single setup. It is installed in a straight-cylindrical toolholder by machinists and CNC programmers working in precision metalworking environments.

This end mill is engineered for use on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Its high-helix flute design and variable index promote chip evacuation and reduce chatter during aggressive cuts. The center-cutting capability allows plunge entry, broadening its use in slotting, profiling, and pocket milling operations. The 5/16 inch length of cut and 4 inch overall length make it well matched to applications requiring reach into tighter part features without sacrificing rigidity.

Key Features

• 5-flute variable index design reduces harmonic vibration during cutting
• EXO coating improves heat resistance and extends tool life in hard and abrasive materials
• Center-cutting geometry enables direct plunge entry
• 0.06 inch corner radius reduces stress concentration and improves surface finish at part transitions
• Extended reach shank allows access to deeper part features
• Compatible with standard straight-cylindrical toolholders

Compatibility

Designed for use with straight-cylindrical toolholders. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials per OSG VGM5-LN series application guidelines.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the toolholder is clean and free of debris before seating the shank, and confirm runout with a dial indicator before starting a cut. Power down and lock out the spindle before changing tooling. Do not exceed the manufacturer-recommended depth of cut or feed rate for the workpiece material being machined.
