Osg VGM5-0186 Corner Radius End Mill 5/8 in 5 Flute Carbide

Product Description

The OSG VGM5-0186 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. It carries a 5/8 inch cutting diameter with a 0.06 inch corner radius, a 1-9/16 inch length of cut, and a 3.5 inch overall length. Five flutes with a variable index geometry and a high helix angle work together to reduce chatter, improve chip evacuation, and extend tool life. The EXO coating adds wear resistance and heat tolerance, making this end mill suitable for both roughing and finishing passes. It is a single-end, right-hand cut tool with a straight cylindrical 5/8 inch shank for use in standard toolholders.

The VGM5-0186 is built for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is well suited to CNC machining centers and milling operations in precision manufacturing, aerospace, die and mold, and general metalworking shops. The centercutting geometry allows direct plunge entry. The standard pitch and spiral flute type make it a versatile choice for a range of cut depths and feed rates across the listed workpiece materials.

Key Features

• 5/8 inch cutting diameter with 0.06 inch corner radius for edge strength and reduced stress concentration
• EXO proprietary coating for improved wear resistance across hard and abrasive workpiece materials
• 5-flute variable index design reduces harmonic vibration and chatter during aggressive cuts
• Centercutting construction enables direct plunge milling without a pre-drilled entry hole
• Right-hand flute direction and right-hand cutting for standard CNC spindle compatibility
• Rated for roughing and finishing in a single tool across steel, stainless, cast iron, superalloys, titanium, and hard materials

Compatibility

Designed for use with standard toolholders accepting a 5/8 inch straight cylindrical shank. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material codes P, M, K, S, H). Part of the OSG VGM5 series.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the toolholder is clean and within the shank diameter tolerance spec (h6) before seating the tool. Confirm spindle direction is set to right-hand before operation. Follow the machine tool manufacturer and OSG series guidelines for recommended speeds, feeds, and depth of cut for the specific workpiece material.
