It features a 3\/16 inch cutting diameter with a 0.045 inch corner radius, producing a controlled fillet at the base of milled features and reducing stress concentrations in the workpiece. The 3\/8 inch length of cut and stub-length geometry provide rigidity in tight-clearance setups. With four spiral flutes and a right-hand cutting direction, it delivers efficient chip evacuation and smooth surface finishes. This tool is installed and operated by machinists and tooling professionals on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finishing and semi-finishing passes in ferrous and non-ferrous metals where a radiused corner profile is required. The bright uncoated finish makes it appropriate for use in materials where coating adhesion is not critical or where re-sharpening is anticipated. The stub-length body keeps deflection low in short-reach applications. Its centercutting capability allows direct plunge entry into the workpiece without a pre-drilled pilot hole, giving operators flexibility in toolpath programming.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.045 inch corner radius produces consistent fillets and reduces stress risers at milled corners\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction provides hardness and wear resistance across a range of materials\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes with right-hand flute direction for efficient chip removal and surface finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge milling without a starter hole\u003c\/li\u003e\n\u003cli\u003eStub-length body minimizes tool deflection and improves rigidity in short-reach setups\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose machining and re-sharpenable applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill for use in standard 3\/16 inch collets or end mill holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and the tool holder is clean and free of chips before seating the tool. Confirm runout with a dial indicator after clamping to the specified shank diameter tolerance range. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting feeds, speeds, and depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.045 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\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\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 Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.0015 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\u003eWeight\u003c\/strong\u003e: 0.03 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: 12182759\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749650432306,"sku":"12182759","price":31.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54793c6bb44eec2285efab057748aeec.jpg?v=1788908791","url":"https:\/\/voomisupply.com\/products\/accupro-12182759-corner-radius-end-mill-3-16in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
