With a 1\/4 inch cutting diameter and a 1 inch length of cut, it delivers sharp, accurate profiles in steel, stainless steel, cast iron, and non-ferrous metals. The 30-degree right-hand helical flute geometry promotes efficient chip evacuation and reduced cutting forces. The bright\/uncoated carbide construction makes it well suited for applications where coating is not required or where re-grinding is planned. Licensed machinists, CNC operators, and tool-and-die professionals will find this end mill a direct fit for standard milling centers and machining cells.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for general-purpose slot milling, profiling, and peripheral cutting across a range of workpiece materials including steel (P-code), stainless steel (M-code), cast iron (K-code), and non-ferrous metals (N-code). Its regular-length geometry and straight cylindrical shank suit it for conventional vertical machining center setups and manual knee mills where a 1\/4 inch collet or end mill holder is used. The Series I3S designation places it within a consistent WIDIA product family for straightforward replacement ordering.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4 inch cutting diameter with 1 inch length of cut for precise slot and profile work\u003c\/li\u003e\n  \u003cli\u003e3 helical flutes with 30-degree helix angle for efficient chip flow and smooth finish\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in metallic workpieces\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable, allowing plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for re-grinding or applications that do not require a coating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement end mill compatible with 1\/4 inch collet chucks, end mill holders, and shrink-fit tooling used on standard CNC vertical machining centers and manual mills.

Ensure the spindle is fully stopped and the machine is in an e-stop or lockout\/tagout state before changing tooling. Seat the straight cylindrical shank fully into the collet or holder and torque the retention mechanism per the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning a cut, and confirm that feed rate, depth of cut, and spindle speed are appropriate for the workpiece material and machine capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.25 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.0000 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\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\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: I3S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.066 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 6144246\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67909260181810,"sku":"6144246","price":46.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/272b737bec8005b23a96a1046c6eeecb.jpg?v=1791185903","url":"https:\/\/voomisupply.com\/products\/widia-6144246-square-end-mill-1-4-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
