Osg 36701311 Corner Radius End Mill 0.2188 in 4 Flute

Product Description

The OSG 36701311 is a solid carbide corner radius end mill designed for precision milling across a wide range of workpiece materials. It features a 0.2188-inch mill diameter, a 0.03-inch corner radius, and four right-hand helical flutes with a 30-degree helix angle. The cutting edge is WXL-coated via PVD process, providing enhanced wear resistance and thermal stability. This is a single-end, centercutting tool, making it capable of plunge entry as well as peripheral and slot milling. It is suited for both roughing and finishing passes and is manufactured from micrograin carbide for consistent performance in demanding applications.

This end mill is intended for use in CNC machining centers and manual mills across job shops, aerospace, and general metalworking environments. It is engineered for use with a standard straight-shank toolholder. Its primary workpiece material categories include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials, making it a versatile choice for machinists working across multiple material types in production and maintenance operations.

Key Features

• 0.03-inch corner radius reduces stress concentrations and extends tool life at the cutting edge
• WXL PVD coating improves hardness and oxidation resistance for high-performance cutting
• Micrograin solid carbide construction delivers rigidity and edge retention
• Centercutting design allows direct plunge milling without a pre-drilled entry point
• Right-hand cut and right-hand flute direction with medium helix for efficient chip evacuation
• Compatible with material grades P, M, K, N, S, and H per standard workpiece classification

Compatibility

Designed for use with standard straight-shank cylindrical toolholders. Suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials as specified by OSG Series 3670 application guidelines.

Installation Notes

Installation is performed by a machinist or tooling technician using a compatible collet or end mill holder sized for a 0.25-inch shank diameter. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify runout and tool projection before initiating a cut. Follow the machine manufacturer and tooling manufacturer recommendations for feeds, speeds, and depth of cut based on workpiece material.
