Osg 447100111 Corner Radius End Mill 1/16 in 4 Flute

Product Description

The OSG 447100111 is a solid carbide corner radius end mill designed for precision milling in demanding materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It features a 1/16 inch cutting diameter, a 0.01 inch corner radius, and four helical flutes ground from micrograin carbide stock. The WXS PVD coating improves wear resistance and heat dissipation, extending tool life in high-speed finishing and light roughing passes. With a 2.25 inch overall length and extended-reach geometry, this tool suits deep-pocket work and tight-clearance setups where standard-length tools cannot reach. It is a right-hand cut, centercutting, single-end tool from OSG Series 4471.

This end mill is suited for CNC machining centers and milling machines used in job shops, aerospace, medical device manufacturing, and precision tooling environments. The extended reach and small diameter make it particularly well-matched to slotting, profiling, and corner-blending operations in hard materials. Its centercutting capability allows direct plunge entry. The high helix angle promotes efficient chip evacuation in ferrous and exotic alloy workpieces. A straight-cylindrical shank fits standard collet toolholders.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention in hard materials
• WXS PVD coating for improved wear resistance in steel, stainless steel, and superalloys
• 0.01 inch corner radius reduces stress concentration and extends part and tool life
• Centercutting design allows direct plunge milling without a pre-drilled entry hole
• Extended reach with 1/4 inch reach length and 0.058 inch neck diameter for deep-pocket access
• Right-hand cut, high helix, helical flute geometry promotes clean chip evacuation

Compatibility

Designed for use with standard collet-style toolholders accepting a 1/8 inch straight-cylindrical shank. Primary workpiece materials are steel, stainless steel, cast iron, superalloys, titanium, and hard materials per OSG Series 4471 application data.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the toolholder collet bore matches the 1/8 inch shank diameter and that runout is minimized before cutting. Power down and lock out the spindle before inserting or removing the tool. Do not exceed the tool's rated depth of cut or length of cut; the 0.4375 inch length of cut dimension defines the usable flute zone.
