Made from sub-micrograin carbide with an IC908 manufacturer grade and a PVD-applied TiAlN coating, this tip delivers wear resistance across a broad range of workpiece materials. It features 4 flutes with a 30-degree helix angle and a 90-degree lead angle, producing a 0.375-inch cutting width and a maximum depth of cut of 0.275 inches. Functional length and overall extension from holder are both 0.512 inches. Right-hand cutting geometry and no chipbreaker define the standard configuration. Licensed HVAC, machining, and tool-and-die professionals install this tip in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis milling tip is suited for applications involving steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials, covering ISO material codes P, M, K, N, S, and H. The MM EC-4 series design makes it appropriate for use in high-productivity milling operations where quick tip changes and consistent performance are required. The 0.030-inch corner radius reduces edge chipping on entry and exit cuts, making it a practical choice for both roughing and semi-finishing passes on difficult-to-machine alloys and hardened materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSub-micrograin carbide substrate with IC908 grade for strength and thermal stability\u003c\/li\u003e\n  \u003cli\u003ePVD TiAlN coating for extended tool life in steel, stainless, and superalloy cuts\u003c\/li\u003e\n  \u003cli\u003e4-flute, 30-degree helix geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e0.030-inch corner radius reduces chipping and improves edge durability\u003c\/li\u003e\n  \u003cli\u003e0.375-inch cutting width with 0.275-inch maximum depth of cut\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation; ANSI standard compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in the ISCAR Multimaster MM EC-4 modular end milling system.

Always de-energize and lock out the machine spindle before changing milling tips. Inspect the holder threads and seating surface for wear or contamination before installing a new tip. Avoid over-torquing the tip connection, as sub-micrograin carbide is brittle and sensitive to improper clamping force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilling Tip Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MM EC-4 (Multimaster)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.512 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.512 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbide (Sub Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: .375A27R030\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel; Stainless Steel; Cast Iron; Non-Ferrous Metal; Superalloys and Titanium; Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\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: 5621476\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748704387378,"sku":"5621476","price":220.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8ff1e6b36c7867d825e3d4f176bcf54.jpg?v=1788897027","url":"https:\/\/voomisupply.com\/products\/iscar-5621476-corner-radius-milling-tip-0-375-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
