With a 1\/8 inch cutting diameter and a 1\/2 inch length of cut, this tool is sized for fine detail work, slotting, and profiling in tight geometries. The 30-degree right-hand helix promotes efficient chip evacuation and smooth cutting action across a wide range of workpiece materials. At 1-1\/2 inches overall length and 0.009 pounds, it is compact and well-suited for CNC machining centers and manual mills where rigidity and accuracy are critical. Solid carbide construction provides the hardness and thermal resistance required for productive cuts in ferrous and non-ferrous applications.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It performs well in profiling, side milling, and slotting passes where a small-diameter tool with reliable chip clearance is required. The uncoated bright finish makes it appropriate for applications where coating interaction with the workpiece material is a concern or where regrinding is anticipated. It is part of the WIDIA I4S series, intended for general-purpose and production milling in machine shops, toolrooms, and manufacturing facilities.\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 fine detail and slot milling\u003c\/li\u003e\n\u003cli\u003e4-flute geometry increases feed rate potential and surface finish quality\u003c\/li\u003e- \u003cli\u003e30-degree right-hand helical flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for hardness, heat resistance, and dimensional stability\u003c\/li\u003e\n\u003cli\u003eCentercutting capable  -  supports plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard collets and end mill holders\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish allows regrinding and suits a broad range of material types\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe WIDIA 5879201 is designed for use in CNC machining centers and manual milling machines equipped with a 1\/8 inch collet or end mill holder. Primary workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials (ISO material codes P, M, K, N, S, H).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the straight-cylindrical shank in a properly sized collet or end mill holder to the tool manufacturer's recommended clamping depth. Verify runout with a dial indicator before beginning the cut, as excessive runout will reduce tool life and surface quality on small-diameter carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 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: 0.5000 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\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: 5879201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67907219259698,"sku":"5879201","price":26.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/559aeb55d436c4ba723853148c2e375a_dc132ff1-8a76-4ee2-9b61-b464a2adca97.jpg?v=1791175746","url":"https:\/\/voomisupply.com\/products\/widia-5879201-square-end-mill-1-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
