It features a 0.5 inch cutting diameter, a 1 inch length of cut, and a 3 inch overall length with a 0.5 inch shank diameter. The tool carries a TiCN (titanium carbonitride) coating applied over a micrograin carbide substrate, which improves surface hardness and wear resistance at the cutting edge. With 2 flutes and a 30-degree helix angle, it is suited for a range of slot milling, peripheral milling, and profiling operations. Centercutting geometry allows plunge cutting directly into the workpiece. Licensed machinists and CNC operators are the primary installers of this tooling.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in vertical machining centers, CNC milling machines, and manual knee mills where a right-hand cut, right-hand spiral flute tool is required. The regular length profile and 0.5 inch shank make it compatible with standard ER collet chucks, end mill holders, and Weldon-style tool holders used in production and job-shop environments. It performs in ferrous metals, stainless steel, cast iron, and similar hard materials where TiCN coating provides a performance advantage over uncoated carbide. The Series 402 designation identifies it within OSG's standard square end mill line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces built-up edge\u003c\/li\u003e\n  \u003cli\u003e30-degree spiral helix angle promotes chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute configuration suits standard CNC spindle rotation\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry provides chip clearance in slotting and pocketing operations\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 compatible with standard 1\/2 inch end mill holders, ER collet chucks, and Weldon-style holders used in CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. The machine spindle must be fully stopped and the tool holder must be de-energized before inserting or removing the end mill. Torque the retention screw or collet nut to the tool holder manufacturer specifications. Verify runout with a dial indicator after seating to ensure proper concentricity before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 402\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 402-500008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749472338226,"sku":"402-500008","price":96.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21da058163a27e35cbe40abcaa79e208.jpg?v=1788906497","url":"https:\/\/voomisupply.com\/products\/osg-402-500008-square-end-mill-1-2-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
