Osg 20480600 Corner Radius End Mill 1/2 in 3 Flute Carbide

Product Description

The OSG 20480600 is a solid carbide corner radius end mill designed for high-performance milling of non-ferrous metals. It features a 1/2 inch cutting diameter, a 0.02 inch corner radius, and three right-hand helical flutes with a coarse pitch. The overall length is 4 inches, with a 1/2 inch length of cut and a 1/2 inch straight-cylindrical shank. The uncoated bright finish is suited to applications where coating buildup or heat sensitivity are concerns. Machinists and toolroom technicians use this end mill in CNC milling centers and manual mills where precise corner geometry and chip control are required on non-ferrous workpieces.

This end mill is rated for primary use on non-ferrous metals, consistent with OSG Series 2048 tooling. The high helix angle promotes efficient chip evacuation in aluminum, copper, brass, and similar materials. The center-cutting geometry allows plunge entry, expanding its utility in pocketing, slotting, and profiling operations. The single-end configuration means it seats in a standard straight-bore toolholder. The reach length of 2.125 inches and neck diameter of 0.496 inches provide clearance for moderate-depth features without sacrificing rigidity.

Key Features

• 0.02 inch corner radius reduces stress concentrations and improves edge life in profiling cuts
• Solid carbide construction delivers rigidity and wear resistance compared to HSS equivalents
• Center-cutting design allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute direction for standard CNC spindle compatibility
• High helix style promotes chip evacuation in non-ferrous and gummy materials
• Straight-cylindrical shank fits standard ER collets and end mill toolholders

Compatibility

Designed for use with standard straight-bore toolholders. Primary workpiece material is non-ferrous metal. Part of OSG Series 2048 long-length corner radius end mill line.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank in a properly sized collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before cutting. Follow all machine guarding and lockout/tagout procedures before changing tooling in any milling machine.
