It features a 0.625 inch cutting width, a 0.47 inch maximum depth of cut, and a 0.81 inch functional length. The tip is manufactured from sub-micrograin carbide in grade IC908 and carries a TiAlN coating applied via PVD process. The 45-degree helix angle and 4-flute geometry are suited to productive metal removal across a broad range of workpiece materials. This tip is installed by machining professionals working on CNC milling equipment in job shop, production, and aerospace environments.\u003c\/p\u003e\n\u003cp\u003eThe 5621384 is configured for right-hand cutting with a 90-degree lead angle and zero corner radius, making it appropriate for square-shoulder milling applications. It is rated for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials, covering ISO material groups P, M, K, N, S, and H. The MM EC-4 interchangeable tip platform allows the tip to be swapped at the machine without removing the holder from the spindle, reducing changeover time in production settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSub-micrograin carbide substrate with IC908 grade designation for wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating for thermal protection and extended tool life across multiple workpiece materials\u003c\/li\u003e\n  \u003cli\u003e4-flute, 45-degree helix geometry for balanced chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003e90-degree lead angle with zero corner radius for true square-shoulder milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation; no coolant-through feature\u003c\/li\u003e\n  \u003cli\u003eANSI standard compliance; Multimaster MM EC-4 series interchangeable tip system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ISCAR Multimaster MM EC-4 series holders that accept the .625B47R000 insert size.

Before swapping tips, ensure the machine spindle is fully stopped and locked out per facility lockout\/tagout procedures. Seat the tip fully into the Multimaster holder interface and torque the retention screw using the appropriate ISCAR Multimaster torque key — do not use substitutes or impact drivers. Verify runout and tip seating before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilling Tip Type\u003c\/strong\u003e: End\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: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.47 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunctional Length\u003c\/strong\u003e: 0.81 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.81 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: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.000 inches\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\/Finish\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: None\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\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 5621384\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748838277426,"sku":"5621384","price":429.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37a1fe1ede0629ef7e5913a73a9d644a.jpg?v=1788899305","url":"https:\/\/voomisupply.com\/products\/iscar-5621384-carbide-milling-tip-4-flute-mm-ec-4","provider":"Voomi Supply","version":"1.0","type":"link"}
