It features a 3\/8-inch mill diameter with a 1\/8-inch (0.1250-inch) corner radius that reduces stress concentrations at the cutting edge and extends tool life in demanding applications. The 4-flute, right-hand spiral configuration promotes efficient chip evacuation and a smooth surface finish. With a stub-length geometry and bright\/uncoated finish, this single-end centercutting tool is suited for use on CNC machining centers and manual mills. It is typically installed by machinists and tooling technicians working in precision manufacturing, tool-and-die, or maintenance machining settings.\u003c\/p\u003e\u003cp\u003eThis end mill is applicable to a wide range of milling tasks including profile milling, slotting, and peripheral cutting where a radiused corner is required to reduce part stress or meet drawing callouts. The stub flute length and solid carbide micrograin construction make it particularly effective in harder workpiece materials where rigidity and edge retention are priorities. It is a single-end tool sold individually and is appropriate for both production and prototype machining work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8-inch mill diameter with 0.1250-inch corner radius for reduced edge stress and improved part geometry\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral design promotes smooth cutting action and efficient chip removal\u003c\/li\u003e\n\u003cli\u003eSolid carbide micrograin construction provides rigidity and edge retention in harder materials\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry directly into the workpiece\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for a wide range of general-purpose milling applications\u003c\/li\u003e\n\u003cli\u003eStub flute length increases tool stiffness and reduces deflection in short-reach setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8-inch shank corner radius end mill compatible with collet chucks, end mill holders, and tooling systems accepting a 3\/8-inch straight shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Ensure the spindle is fully stopped and the machine is powered down or in a safe lockout\/tagout state before changing tooling. Seat the shank fully into the holder to the recommended gauge-line depth and torque the retention mechanism per the toolholder manufacturer's specification. Verify runout at the cutting edge after installation before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/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\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\u003eWeight\u003c\/strong\u003e: 0.11 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: 12182873\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748794958130,"sku":"12182873","price":53.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c26e5c9fe84c80e7beb602a119acfc0f.jpg?v=1788898480","url":"https:\/\/voomisupply.com\/products\/accupro-12182873-corner-radius-end-mill-3-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
