With a 3\/4 inch cutting diameter, 1-1\/2 inch length of cut, and 4 helical flutes at a 30-degree helix angle, it delivers efficient chip evacuation and stable cutting action across a range of ferrous and exotic workpiece materials. The TiAlN coating provides elevated heat resistance and surface hardness, extending tool life in high-temperature cutting conditions. This is a single-end, right-hand cut, right-hand flute tool in the I4S series, suited for use in CNC machining centers and manual mills operated by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThe 5879558 is rated for primary use in steel, stainless steel, and cast iron, and extends to secondary applications including hardened materials, aluminum and non-ferrous alloys, and high-temperature alloys. The 3\/4 inch Weldon flat shank provides positive drive and reduces slippage in end mill holders. At 4 inches overall length with a regular-length designation, this tool fits standard toolholding setups without requiring extended-reach adaptors. It is center-cutting, allowing direct plunge entry into workpieces where required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for improved heat resistance and extended tool life in dry or semi-dry cutting\u003c\/li\u003e\n  \u003cli\u003e4 helical flutes at 30-degree helix angle for efficient chip evacuation and smooth finish\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable for direct plunge milling operations\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank for positive engagement in standard end mill holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute geometry for conventional CNC and manual mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 3\/4 inch end mill holders or collet chucks.

Seat the Weldon flat shank securely against the setscrew in the toolholder to prevent axial pullout under cutting load. Verify runout with a dial indicator after mounting before initiating cuts. Follow machine manufacturer and tooling supplier guidelines for speeds, feeds, and depth of cut appropriate to 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: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\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\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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\u003eChipbreaker\u003c\/strong\u003e: No\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: I4S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hardened Materials, Cast Iron, Stainless Steel, Aluminum and Non-Ferrous, Steel, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.753 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: WIDIA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5879558\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67917617889586,"sku":"5879558","price":301.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/559aeb55d436c4ba723853148c2e375a_e014cf98-5377-4eb8-b7ab-29668d0fcb36.jpg?v=1791264272","url":"https:\/\/voomisupply.com\/products\/widia-5879558-square-end-mill-3-4-in-4-flute-tialn-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
