Osg 84400423 Square End Mill 1/8 in 4 Flute Solid Carbide

Product Description

The OSG 84400423 is a solid carbide square end mill designed for precision milling in a wide range of metalworking and machining applications. With a 1/8 inch cutting diameter and four flutes, it delivers clean, accurate cuts in ferrous and non-ferrous materials. The DUROREY coating enhances surface hardness and heat resistance, extending tool life in demanding cutting conditions. A 43-degree helix angle promotes efficient chip evacuation and reduces cutting forces, making this end mill well suited for finishing passes and contour work. It is a single-end, right-hand cutting tool intended for use in CNC machining centers and manual milling machines operated by qualified machinists.

This end mill is appropriate for precision slot milling, profiling, and contouring operations in job shop, production, and tool-and-die environments. The 5/16 inch length of cut and 1/4 inch shank diameter make it compatible with standard collet systems and end mill holders. Its micrograin carbide construction supports high surface-speed applications and tight-tolerance work in materials including aluminum, steel, stainless steel, and hardened alloys. The compact cutting diameter suits fine-detail work and narrow slot geometries.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• DUROREY coating for extended tool life and improved heat resistance
• 43-degree helix angle for efficient chip evacuation and reduced cutting forces
• Four flutes for smooth surface finish and productive material removal
• Right-hand cut and right-hand flute geometry for standard spindle operation
• Center-cutting design allows plunge entry into workpiece

Compatibility

Designed as a direct-fit replacement for standard 1/4 inch shank end mill holders and collet chucks used in CNC machining centers and manual milling machines requiring a 1/8 inch diameter square end mill.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or end mill holder to the recommended grip length and verify runout before commencing cuts. Do not exceed the rated cutting parameters for the workpiece material and coating type.
