It features a 1\/4 inch diameter cutting edge with a 0.06 inch corner radius, a 3\/4 inch length of cut, and a 2-1\/2 inch overall length. The two-flute, right-hand spiral geometry and centercutting capability allow it to plunge directly into workpiece material. Manufactured from micrograin solid carbide with a bright uncoated finish, this end mill suits machinists and toolroom operators working on close-tolerance profiling, slotting, and contouring passes where corner radius blending is required.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual knee mills handling ferrous and non-ferrous stock. The single-end configuration and 40-degree helix angle make it effective for light-to-medium material removal where controlled chip evacuation and surface finish quality are priorities. It is a standard choice for job shops, toolrooms, and production machining cells requiring repeatable corner radius geometry on milled features.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4 inch mill diameter with 0.06 inch corner radius for blended edge profiling\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e2-flute right-hand spiral geometry with centercutting capability\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 3\/4 inch length of cut and 2-1\/2 inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1\/4 inch shank corner radius end mill compatible with collet chucks, end mill holders, and shrink-fit tooling systems accepting 1\/4 inch round shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard tool-holding and runout verification procedures. Ensure the shank is fully seated and clamped to the minimum grip depth recommended for the holder type in use. Verify spindle and holder runout before committing to finish passes, as micrograin carbide tooling is sensitive to excessive runout. Consult applicable shop safety procedures and machine tool manufacturer guidelines before operating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12181335\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739655078194,"sku":"12181335","price":35.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ab5f737e3ef65945e00d479ba6a9fbb.jpg?v=1788817405","url":"https:\/\/voomisupply.com\/products\/accupro-12181335-corner-radius-end-mill-1-4-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
