Osg 402-3438 Square End Mill 11/32 Inch 2 Flute Carbide

Product Description

The OSG 402-3438 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 0.3438 inch (11/32 inch) cutting diameter and a 0.875 inch length of cut, with a 0.375 inch shank diameter and a 2.5 inch overall length. The two-flute, spiral design runs a 30-degree helix angle with right-hand cut and right-hand flute orientation. Manufactured from micrograin solid carbide, this end mill is built for rigidity and edge retention in demanding cutting operations. It is centercutting capable, allowing plunge cuts in addition to standard peripheral milling. Licensed machinists and CNC operators are the primary installers and users of this tooling.

This end mill is suited for profiling, slotting, and light plunge operations on ferrous and non-ferrous materials in both manual and CNC milling environments. The uncoated micrograin carbide construction makes it a reliable choice for general-purpose machining where a coating is not required or where regrinding is anticipated. The regular-length geometry fits standard toolholders and collet chucks commonly found in job shop and production machining setups. It is sold individually as a single-piece unit.

Key Features

• Solid micrograin carbide construction for superior rigidity and edge retention
• Two-flute spiral design with 30-degree helix for efficient chip evacuation
• Centercutting geometry allows plunge entry cuts
• Right-hand cut and right-hand flute orientation for standard CNC and manual mill use
• Uncoated finish suitable for applications where regrinding is preferred
• Regular-length profile fits standard collet chucks and toolholders

Compatibility

Designed as a general-purpose solid carbide square end mill compatible with standard 3/8 inch collet chucks and toolholders used in CNC machining centers and manual milling machines.

Installation Notes

Installation and use of this end mill should be performed by qualified machinists familiar with proper toolholder torque practices and machine spindle speeds. Ensure the milling machine spindle is fully stopped and locked before inserting or removing the tool from the collet or toolholder. Verify that the shank is fully seated and the collet nut is properly tightened before beginning any cut. Always reference the machine manufacturer and tooling manufacturer guidelines for recommended speeds and feeds based on workpiece material.
