Osg 44700611 Corner Radius End Mill 1/2 in 4 Flute Carbide

Product Description

The OSG 44700611 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining applications. Built on OSG Series 4470, it features a 1/2 inch cutting diameter with a 1/8 inch corner radius that reduces stress concentration at the cutting edge and extends tool life. The micrograin carbide substrate is finished with a WXS coating for improved wear resistance and heat management. With 4 flutes and a single-end, centercutting configuration, this tool handles slotting, profiling, and ramping in a single setup. It is sized for use in CNC machining centers and manual mills with a 1/2 inch collet or end mill holder.

This end mill is suited for ferrous and non-ferrous metal machining in production and job-shop environments. The extended reach design, with a 2 inch reach length and a 0.46 inch neck diameter, allows access to deeper pockets and stepped features without tool interference. The 0.2 inch length of cut is optimized for finish passes and light material removal in tight geometries. Machinists and CNC programmers working in aerospace, automotive, and general metalworking will find this tool fits standard roughing-to-finish workflows where edge radius is specified on the part drawing.

Key Features

• 1/8 inch corner radius reduces edge chipping and improves surface finish at part corners
• WXS coating provides wear resistance and thermal protection during high-speed cuts
• Micrograin solid carbide substrate for rigidity and edge retention
• Extended reach with 2 inch reach length and 0.46 inch neck diameter for deep pocket access
• Centercutting design enables direct plunge entry and ramping operations
• Right-hand cut, right-hand flute direction compatible with standard CNC spindle rotation

Compatibility

Designed for use in CNC machining centers and manual milling machines accepting a 1/2 inch straight shank via collet chuck or end mill holder. Part of the OSG Series 4470 corner radius end mill family.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully into the tool holder to the recommended gauge length before tightening. Verify spindle speed and feed rate against the material being cut and the tool manufacturer application data before running. Inspect the cutting edges and coating condition before each use; do not run a chipped or damaged end mill.
