Osg 36701211 Corner Radius End Mill 0.2188 in 4 Flute

Product Description

The OSG 36701211 is a solid carbide corner radius end mill designed for high-performance milling in demanding metalworking applications. It features a 0.2188-inch mill diameter, a 0.02-inch corner radius, and four right-hand helical flutes with a 30-degree helix angle. The cutting edge is center-cutting and single-end, making it suitable for both plunge and peripheral milling operations. A WXL physical vapor deposition (PVD) coating improves wear resistance and heat management during cutting. This tool is used by machinists and CNC operators working in job shops, tool rooms, and production environments.

The OSG 36701211 is engineered for 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 0.2188-inch diameter and 1/4-inch straight-cylindrical shank fit standard toolholders used in vertical machining centers and CNC milling machines. The 5/8-inch length of cut and 2.5-inch overall length suit shallow-to-moderate depth pocketing, slotting, and profiling in production and prototype work.

Key Features

• 0.02-inch corner radius reduces stress concentrations and extends tool life at corners
• WXL PVD coating provides enhanced hardness and heat resistance for extended cutting performance
• Four right-hand flutes with 30-degree medium helix support efficient chip evacuation
• Center-cutting geometry allows direct plunge entry without pre-drilling
• Micrograin solid carbide substrate delivers rigidity and edge retention in hard and abrasive materials
• Straight-cylindrical 1/4-inch shank fits standard collet and milling toolholders

Compatibility

Designed for use with standard milling toolholders. Compatible with vertical machining centers and CNC mills accepting a 1/4-inch straight-cylindrical shank. Suitable for OSG Series 3670 tooling setups.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the toolholder is secure before inserting or removing the end mill. Verify runout after clamping to stay within tolerance for the application. Follow the machine manufacturer and toolholder manufacturer guidelines for appropriate clamping torque and projection length.
