Osg 404-093911 Square End Mill 3/32 in 4 Flute Carbide

Product Description

The OSG 404-093911 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. With a 3/32 inch (0.0938 inch) cutting diameter and a 3/8 inch length of cut, this tool handles slotting, profiling, and peripheral milling tasks where tight tolerances are required. The TiAlN coating improves heat resistance and tool life during high-speed cutting. Four spiral flutes with a 30-degree helix angle promote chip evacuation and surface finish quality. This end mill is centercutting, allowing plunge entry into workpieces. It is installed and used by machinists and CNC operators working on mills and machining centers.

This end mill is suited for use in both manual and CNC milling applications where small-diameter, high-precision cutting is needed. The 1/8 inch shank diameter fits standard collets and tool holders used in machining centers handling fine detail work. Typical applications include mold making, die work, aerospace component machining, and general precision part production. The right-hand cut and right-hand flute configuration is the standard orientation for conventional milling setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cutting conditions
• TiAlN finish provides elevated heat resistance, extending tool life at higher cutting speeds
• Centercutting design allows direct plunge entry without pre-drilling
• 30-degree helix angle with spiral flutes promotes efficient chip evacuation
• Four-flute configuration supports improved surface finish on finish passes
• Right-hand cut and right-hand flute for standard milling machine compatibility

Compatibility

Designed to fit standard 1/8 inch collets and tool holders on CNC machining centers and manual milling machines requiring a small-diameter square end mill in the OSG Series 404 line.

Installation Notes

This tool is installed by machinists using appropriate collet or end mill holder systems rated for the 1/8 inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet runout is within acceptable limits before beginning cuts, as runout has a significant effect on tool life and part accuracy at small diameters. Follow machine manufacturer guidelines and applicable shop safety standards when setting speeds and feeds.
