Osg 447101011 Corner Radius End Mill 3/16 in 4 Flute Carbide

Product Description

The OSG 447101011 is a solid carbide corner radius end mill designed for precision milling of ferrous and hard materials. The cutter measures 3/16 inches in diameter with a 3/16 inches length of cut and a 0.02 inch corner radius, making it well-suited for producing smooth transitions and reducing stress concentrations at part corners. With four flutes, a high helix angle of 45 degrees, and OSG WXS PVD coating, this tool is built to handle demanding cutting applications including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is a single-end, center-cutting design with right-hand flute direction and right-hand cutting direction. Overall length is 2.25 inches with a 3/16 inch straight cylindrical shank and a 0.5 inch reach length.

This end mill is intended for use in CNC machining centers and milling applications where controlled corner geometry and surface finish are required. The extended reach configuration and micrograin carbide substrate make it appropriate for tight-tolerance work in aerospace, tooling, and precision manufacturing environments. It is part of OSG Series 4471 and is compatible with standard toolholders. Material removal capability covers both roughing and finishing operations across a wide range of workpiece materials.

Key Features

• Solid micrograin carbide substrate for wear resistance in hard and abrasive materials
• WXS PVD coating for extended tool life in steel, stainless, cast iron, superalloys, and hard materials
• 0.02 inch corner radius reduces edge chipping and stress risers on finished parts
• 45-degree high helix promotes efficient chip evacuation and smooth surface finish
• Center-cutting design allows plunge entry
• Extended reach with 0.5 inch reach length for access to deeper features

Compatibility

Designed for use with standard CNC toolholders. Suitable for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials as specified by OSG for the Series 4471 line.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the toolholder is clean and free of debris before seating the shank. Verify runout after installation to protect the cutting edge and maintain tolerance. Follow machine tool manufacturer guidelines for speeds, feeds, and clamping torque for the toolholder type in use.
