It features a 1\/2 inch diameter cutting edge with a 1-1\/2 inch length of cut and a 6 inch overall length. The 3-flute geometry combined with a 45-degree helix angle promotes efficient chip evacuation and smooth cutting action. A Diamond-Like Carbon (DLC) coating adds surface hardness and reduces friction, extending tool life in demanding cuts. The submicron carbide grade provides toughness and wear resistance. This end mill is a single-end tool with a right-hand cutting and flute direction, suited for CNC machining centers and manual mills operated by experienced machinists.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for profiling, slotting, and peripheral milling operations in ferrous and non-ferrous materials where a sharp, close-tolerance corner is required. The centercutting capability allows plunge entry directly into the workpiece. The variable index design helps reduce harmonic vibration during long cuts, making it appropriate for both roughing and finishing passes in production and job-shop environments. Its 1\/2 inch shank diameter fits standard ER and end mill holders commonly found on vertical machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with submicron grain material grade for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eDLC coating reduces friction and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces harmonic chatter during operation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute direction for standard CNC and manual mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide square end mill compatible with standard 1\/2 inch end mill holders, collet chucks, and ER-style toolholders used on vertical machining centers and CNC mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully powered down and the tool changer is in a safe state before changing tooling. Confirm the shank is fully seated in the holder to the minimum insertion depth before tightening. Inspect the cutting edges for chips or damage before each use, and do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (1.5 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: DLC (Diamond-Like Carbon)\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3398972\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51739256619314,"sku":"3398972","price":233.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ba32a6c345bc1a81625bb9fb60cc37b_dad914b7-08d3-43cf-a579-9ede52db9c3a.jpg?v=1788812236","url":"https:\/\/voomisupply.com\/products\/iscar-3398972-square-end-mill-1-2-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
