Built from micrograin solid carbide, this single-end tool features a 3\/8 inch cutting diameter, a 0.045 inch corner radius, and 4 spiral flutes with a 40-degree helix angle. The bright uncoated finish makes it well suited for non-ferrous materials and general-purpose milling where coatings are not required. It is a centercutting design, allowing plunge entry directly into the workpiece. Machinists and tool-and-die professionals install and operate this end mill in CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish milling, profiling, slotting, and contouring operations in ferrous and non-ferrous materials. The stub length classification and 5\/8 inch length of cut make it particularly effective in applications requiring rigidity and minimal tool deflection. The right-hand flute direction and right-hand cutting orientation are standard for the majority of vertical and horizontal milling setups found in job shop and production machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003e0.045 inch corner radius reduces stress concentration and extends workpiece edge life\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip evacuation and surface finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003eStub length classification provides added rigidity to minimize deflection in tight setups\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for non-ferrous materials and general-purpose applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 3\/8 inch collets and end mill holders used in CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle and collet or end mill holder are clean and free of debris before seating the 3\/8 inch shank. Confirm tool stick-out is minimized to maintain rigidity consistent with the stub length classification. Always verify spindle speed and feed rate parameters against material-specific cutting data before engaging the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\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 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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin 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\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\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: 12182877\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729315070258,"sku":"12182877","price":53.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54df4fe20418a555309971444f32369b.jpg?v=1788702798","url":"https:\/\/voomisupply.com\/products\/accupro-12182877-corner-radius-end-mill-3-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
