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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for edge stability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life in ferrous and non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003eFive flutes with 45-degree spiral helix for improved chip flow and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for use with standard spindle direction\u003c\/li\u003e\n  \u003cli\u003eMatching 3\/8 inch cutting diameter and shank diameter simplifies toolholder selection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned 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.

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.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.8000 to 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 455C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 455-375208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734109716786,"sku":"455-375208","price":70.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f89e1b745c670d244c6a7066d779ea0.jpg?v=1788760965","url":"https:\/\/voomisupply.com\/products\/osg-455-375208-square-end-mill-3-8-in-5-flute-carbide-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
