Osg 412-0469 Square End Mill 3/64 in 2 Flute Solid Carbide

Product Description

The OSG 412-0469 is a solid carbide square end mill engineered for precision milling in tight geometries and small-feature work. Built to Series 412 specifications, it features a 3/64 inch (0.0469 inch) cutting diameter and a 3/32 inch (0.0938 inch) length of cut, making it well suited for fine detail passes and slot milling where cutter size is critical. The micrograin carbide substrate supports edge sharpness and wear resistance in demanding applications. A 30-degree helix angle promotes efficient chip evacuation while maintaining cutting stability at small diameters. This tool is installed by machinists and tool-and-die professionals working on CNC milling centers and manual mills.

The 412-0469 is designed for applications requiring precise small-diameter cutting in metals, plastics, and composites. The stub-length configuration - with a 1-1/2 inch overall length and a 1/8 inch shank diameter - provides rigidity and reduces deflection during light finishing passes, contour milling, and slot cutting in small workpieces or confined areas. The uncoated micrograin carbide construction makes it a reliable choice when cutting non-ferrous metals or materials where coating adhesion is not required.

Key Features

• 3/64 inch cutting diameter for fine detail and small-feature milling
• Solid micrograin carbide construction for edge retention and wear resistance
• 30-degree spiral flute helix for effective chip evacuation
• Center-cutting capable - supports direct plunge entry
• Right-hand cut and right-hand flute configuration
• Stub-length body reduces deflection in precision setups
• Uncoated finish suitable for non-ferrous and select ferrous applications

Compatibility

Designed for use in standard 1/8 inch collets or end mill holders on CNC machining centers and manual milling machines; part of the OSG Series 412 square end mill family.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and machine power secured. Verify collet and holder bore size matches the 1/8 inch shank before tightening. At small diameters, minimize runout at the collet to reduce the risk of tool breakage. Follow machine tool manufacturer guidelines and applicable shop safety procedures during setup.
