Osg 3101011 Corner Radius End Mill 1mm 2 Flute Carbide

Product Description

The OSG 3101011 is a solid carbide corner radius end mill designed for precision milling of steel, stainless steel, and hard materials. It features a 1 mm mill diameter with a 0.2 mm corner radius and a 0.8 mm length of cut, making it suited for tight-tolerance finishing and light roughing passes in difficult-to-machine alloys. The WXS PVD coating improves wear resistance and heat dissipation at the cutting edge. With a 4 mm straight-cylindrical shank and an extended-reach neck configuration, this tool fits standard toolholders used on CNC machining centers. Licensed machinists and tool-and-die professionals are the primary users of this type of end mill.

The 3101011 is built for applications involving steel, stainless steel, and hard materials where a small-diameter corner radius profile is required. Its stub-length flute geometry and extended reach of 4 mm suit deep-pocket or shoulder milling operations where a conventional short-reach tool cannot access the feature. The coarse pitch and 30-degree helical flute design support chip evacuation during aggressive passes. This tool is used in job-shop, aerospace, and medical-component machining environments where dimensional accuracy on corner radii is critical.

Key Features

• 1 mm mill diameter with 0.2 mm corner radius for precise profile milling
• WXS PVD coating for extended tool life on steel and hard materials
• Solid carbide construction provides rigidity in small-diameter applications
• Extended-reach neck with 0.95 mm neck diameter for deep-feature access
• Right-hand cut, right-hand flute, center-cutting design
• Corner radius tolerance of plus 5 to minus 5 micrometers for tight fitment

Compatibility

Designed for use with standard CNC toolholders. Rated for primary workpiece materials coded P, M, and H: steel, stainless steel, and hard materials. Part of the OSG Series 4592 extended-reach stub end mill family.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Seat the 4 mm straight-cylindrical shank fully into a compatible toolholder and torque the retention mechanism per the toolholder manufacturer specification. Inspect the corner radius and cutting edges for chips or coating damage before use. Do not exceed the rated length of cut of 0.8 mm axially without confirming deflection and runout are within tolerance for the application.
