Built to Series I4S standards, it features a 1-inch cutting diameter and a 3-inch length of cut, making it well-suited for deep slotting, profiling, and peripheral milling operations. The 4-flute, right-hand helical geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiAlN coating extends tool life by improving heat resistance and reducing friction at elevated cutting temperatures. This end mill is installed and operated by machinists and tooling professionals in CNC and manual milling environments.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for use on steel, stainless steel, and cast iron as primary workpiece materials. Secondary material compatibility includes hardened materials, aluminum and non-ferrous alloys, high-temp alloys, and additional grades of stainless steel and cast iron. With a Weldon flat shank and 1-inch shank diameter, it mounts securely in standard end mill holders and side-lock toolholders. It is a single-end tool, meaning the cutting end is not reversible. Typical applications include mold work, fixture fabrication, and general precision part machining in job shop and production settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch cutting diameter with 3-inch length of cut for deep-reach milling\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand helical geometry with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for extended tool life in high-heat cutting environments\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank for secure, slip-resistant toolholder engagement\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing plunge entry into workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with primary workpiece materials including steel, stainless steel, and cast iron.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the Weldon flat against the set screw in the holder to prevent axial pullout under cutting loads. Confirm tool projection and runout with a dial indicator before beginning cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 3 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eVariable Index\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\u003eSeries\u003c\/strong\u003e: I4S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.912 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WIDIA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5879566\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67915343200562,"sku":"5879566","price":705.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/559aeb55d436c4ba723853148c2e375a_eb681e18-cb11-4a92-82c9-184aa2c980dd.jpg?v=1791253203","url":"https:\/\/voomisupply.com\/products\/widia-5879566-square-end-mill-1in-4-flute-solid-carbide-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
