Osg 457105011 Corner Radius End Mill 5mm 4-flute Carbide

Product Description

The OSG 457105011 is a solid carbide corner radius end mill designed for high-performance milling in demanding machining environments. With a 5 mm cutting diameter, 0.2 mm corner radius, and 4 helical flutes at a 45-degree high helix angle, this tool delivers both roughing and finishing capability in a single pass. The WXS PVD coating improves wear resistance and heat dissipation, extending tool life when cutting hard or abrasive materials. The extended-reach neck design, with a 4.80 mm neck diameter and 15 mm reach length, provides clearance in deep-pocket and stepped-feature applications. Licensed machinists and CNC operators working in precision job shops and production environments are the primary users of this tool.

This end mill is built for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The Series 4571 geometry is suited for right-hand cutting with normal pitch fluting and a straight cylindrical shank. The 6 mm shank diameter is compatible with standard collet-style toolholders. The 8 mm length of cut and 80 mm overall length make it well-matched to typical vertical machining center setups handling small-diameter profiling, slotting, and contouring work.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard-material applications
• WXS PVD coating for extended tool life when cutting steel, stainless steel, and superalloys
• 0.2 mm corner radius reduces stress concentration and edge chipping on part corners
• 45-degree high helix angle promotes efficient chip evacuation and smooth surface finish
• Extended-reach neck (15 mm reach, 4.80 mm neck diameter) allows access to deep pockets without tool change
• Center-cutting design permits plunge entry and ramp milling
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation

Compatibility

Designed for use with collet-style toolholders accepting a 6 mm straight cylindrical shank. Suitable for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials in CNC milling applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the toolholder. Seat the shank to the recommended gauge-line depth in the collet and torque the collet nut per the toolholder manufacturer specification. Confirm runout with a dial indicator before initiating a cut, as excessive runout accelerates edge wear and reduces corner radius accuracy.
