Osg 36702311 Corner Radius End Mill 3/8 in 4 Flute Carbide

Product Description

The OSG 36702311 is a solid carbide corner radius end mill designed for high-performance metal removal and finishing in demanding machining applications. Built to Series 3670 specifications, it features a 3/8 inch diameter, a 0.06 inch corner radius, and four right-hand helical flutes with a 30-degree medium helix angle. The WXL PVD coating improves wear resistance and heat management during extended cuts. Center-cutting geometry allows plunge entry, and the single-end configuration suits standard toolholder setups on CNC milling machines. Licensed machinists and tool-and-die professionals are the primary users of this end mill.

This end mill is suited for both roughing and finishing operations across a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its 1 inch length of cut and 2.5 inch overall length make it appropriate for moderate-depth slotting, profiling, and contouring passes in vertical and horizontal machining centers. The straight cylindrical shank fits standard collet chucks and shrink-fit toolholders with a 3/8 inch bore.

Key Features

• Solid carbide micrograin construction for rigidity and edge retention in hard and abrasive materials
• WXL PVD coating reduces friction and extends tool life in steel and stainless steel applications
• 0.06 inch corner radius reduces stress concentration at the cutting edge and improves surface finish
• Center-cutting design enables direct plunge milling without a pre-drilled entry hole
• Right-hand cut, right-hand flute, normal pitch configuration with no chipbreaker for smooth chip flow
• Compatible with both roughing and finishing passes across ferrous and non-ferrous workpieces

Compatibility

Designed for use with standard toolholders accepting a 3/8 inch straight cylindrical shank. Suitable for machining steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials as specified by OSG for the Series 3670 line.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before loading or removing the end mill from the toolholder. Ensure the shank is fully seated and the toolholder is torqued per the toolholder manufacturer's specifications. Inspect the cutting edges for chips or wear before each run, particularly when machining superalloys or hardened materials.
