With a 1\/8 inch cutting diameter and a TiAlN coating, it delivers high heat resistance and extended tool life at elevated cutting speeds. The 30-degree right-hand helical flute geometry promotes efficient chip evacuation and smooth surface finishes. This end mill is center-cutting, allowing plunge entry, and features a straight cylindrical shank for secure toolholder engagement. It is primarily used by machinists and CNC operators in job shops, production facilities, and toolroom environments.\u003c\/p\u003e\u003cp\u003eThe 5879131 is built for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The 1\/2 inch length of cut and 1-1\/2 inch overall length make it well suited for finishing passes, slotting, and profiling in tight geometries or small-part work. The regular length profile fits standard toolholders used on vertical machining centers and CNC mills where small-diameter tooling is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/8 inch cutting diameter with 1\/2 inch length of cut for small-feature milling\u003c\/li\u003e\n\u003cli\u003e4-flute solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN coating provides thermal barrier and oxidation resistance at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix promotes chip flow and reduces cutting force\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard collet and toolholder systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a solid carbide square end mill replacement suitable for use in CNC machining centers and manual mills equipped with standard 1\/8 inch collets or toolholders.

Ensure the machine spindle is fully stopped and the tool changer or collet is de-energized before inserting or removing the end mill. Use a torque wrench and the collet manufacturer's specified seating procedure to secure the shank without over-tightening. Verify runout with a dial indicator before initiating cuts on close-tolerance features.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.5 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\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: Straight Cylindrical\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\u003eCenter Cutting\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\u003eChipbreaker\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\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: 0.009 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 5879131\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67909313233202,"sku":"5879131","price":32.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/559aeb55d436c4ba723853148c2e375a_953505d4-5469-41a0-8bf5-c27312b7ce43.jpg?v=1791186215","url":"https:\/\/voomisupply.com\/products\/widia-5879131-square-end-mill-1-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
