With a 0.25 inch (1\/4 inch) diameter and a 0.75 inch length of cut, this four-flute tool delivers stable chip evacuation and consistent surface finish in ferrous and non-ferrous materials. The 30-degree right-hand helical flute geometry reduces cutting forces and promotes efficient chip flow. At 2.5 inches overall length with a straight cylindrical 0.25 inch shank, it fits standard collet and end mill holders used by machinists in production and job-shop environments. Center-cutting capability allows plunge entry into workpieces.\u003c\/p\u003e\u003cp\u003eThe 5879206 is suited for slot milling, shoulder milling, and profile milling operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The regular-length, single-end configuration makes it a versatile choice for general-purpose machining where tool rigidity and repeatability are priorities. It is commonly used in CNC machining centers and manual knee mills across aerospace, automotive, and general fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003e4-flute, 30-degree right-hand helix for balanced chip load and surface finish\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge milling without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids on a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard collet chucks and end mill holders\u003c\/li\u003e\n\u003cli\u003eCompatible with steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option in the WIDIA I4S series for machining centers and manual mills using 1\/4 inch collet or end mill holder systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator familiar with tool-holding torque requirements and runout tolerances. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended gage line depth to prevent tool pullout under cutting load. Verify runout with a dial indicator before production cuts, particularly in tight-tolerance applications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches (2-1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle\/Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: I4S\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: 0.057 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: 5879206\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67918175174962,"sku":"5879206","price":41.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/559aeb55d436c4ba723853148c2e375a_77a491d1-966e-4a5e-86f8-b3b5cc73914b.jpg?v=1791267967","url":"https:\/\/voomisupply.com\/products\/widia-5879206-square-end-mill-1-4-inch-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
