With a 3\/16 inch mill diameter and a 0.015 inch corner radius, this single-end tool produces controlled edge breaks and contoured profiles while maintaining tight dimensional tolerances. The 4-flute, right-hand spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. The bright\/uncoated finish suits a range of general-purpose milling tasks. Licensed machinists and toolroom technicians working on CNC mills and manual knee mills will find this tool appropriate for finishing passes on steel and other ferrous materials.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard milling applications in job shops, tool and die operations, and production machining environments. The long-length designation, with a 1 inch length of cut and 4 inch overall length, provides reach for deeper pockets and stepped features. Centercutting capability allows direct plunge entry into workpieces without pre-drilling. The micrograin carbide substrate supports use in harder materials where high-speed steel tooling would wear prematurely.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/16 inch mill diameter with matching 3\/16 inch shank diameter for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003cli\u003e0.015 inch corner radius reduces stress concentration at milled edges and extends part life\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with 40-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for wear resistance in ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for general-purpose dry and wet milling operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or new-stock corner radius end mill compatible with standard 3\/16 inch collets, shrink-fit holders, and end mill adapters used on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully into the holder to the minimum insertion depth recommended for the holder type, and torque retention screws or collet nuts to the holder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate corner radius wear and affect dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch\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: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 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: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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 (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 12183452\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748302029106,"sku":"12183452","price":56.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/117a9a0c99705ea61fde78369e47641a.jpg?v=1788892062","url":"https:\/\/voomisupply.com\/products\/accupro-12183452-corner-radius-end-mill-3-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
