Osg 455-375208 Square End Mill 3/8 in 5 Flute Carbide Ticn

Product Description

The OSG 455-375208 is a solid carbide square end mill engineered for high-performance milling in ferrous and non-ferrous materials. It features a 3/8 inch cutting diameter, a 7/8 inch length of cut, and a 3/8 inch shank diameter, with an overall length of 2-1/2 inches. The five-flute spiral geometry with a 45-degree helix angle promotes efficient chip evacuation and smooth surface finishes at higher feed rates. A TiCN (Titanium Carbonitride) coating increases surface hardness and reduces friction, extending tool life in demanding cutting conditions. This end mill is centercutting, allowing plunge operations, and is manufactured from micrograin solid carbide for consistent edge integrity.

The OSG 455-375208 belongs to the Series 455C and is suited for general-purpose and finish milling operations in machine shops, tool rooms, and production environments. It is configured for right-hand cut and right-hand flute direction, making it compatible with standard CNC machining centers and manual milling machines. The 45-degree helix is particularly effective in applications requiring reduced cutting forces and improved surface finish on aluminum, steel, and similar materials. Extended reach is not a feature of this tool, positioning it as a compact, rigid option for standard-depth pockets and profiles.

Key Features

• Solid micrograin carbide construction for edge stability and wear resistance
• TiCN coating reduces friction and extends tool life in ferrous and non-ferrous applications
• Five flutes with 45-degree spiral helix for improved chip flow and surface finish
• Centercutting geometry enables direct plunge entry without a pre-drilled hole
• Right-hand cut and right-hand flute for use with standard spindle direction
• Matching 3/8 inch cutting diameter and shank diameter simplifies toolholder selection

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for standard 3/8 inch collet chucks, end mill holders, and shrink-fit toolholders used in CNC machining centers and manual milling machines. Part of the OSG Series 455C product family.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the toolholder is clean and free of chips before seating the shank to the correct retention depth. Verify spindle direction and programmed feed and speed parameters before initiating a cut. Do not exceed the tool's rated length of cut range of 0.8000 to 1.0000 inches when engaging material at full depth.
