Built with a 3\/16 inch diameter and a 0.02 inch corner radius, it produces a consistent, blended edge profile that reduces stress concentrations in machined pockets, slots, and contours. The single-end, center-cutting design allows plunge entry as well as standard peripheral cutting. With a micrograin carbide substrate and a bright uncoated finish, this tool is suited for applications where coolant is used or where coating-free contact is required. Machinists and tool-and-die shops running 3-axis and 5-axis CNC mills are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is used in general machining environments where a small-diameter corner radius tool is needed for finishing passes, slot milling, and contour work. The 5\/8 inch length of cut provides adequate reach for shallow-to-mid-depth pockets without sacrificing rigidity. The right-hand cutting direction and right-hand spiral flute geometry make it compatible with standard CNC machining center spindle rotation. It is a single-quantity, single-end tool packaged for individual use in production or maintenance machining settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.02 inch corner radius reduces edge chipping and stress risers in finished workpieces\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction provides rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of cutting fluids and base materials\u003c\/li\u003e\n\u003cli\u003e2-flute configuration promotes chip evacuation in softer materials and confined pockets\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle improves surface finish and reduces cutting forces\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 CNC machining centers and manual mills accepting a 3\/16 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard CNC tooling procedures. Ensure the spindle is fully stopped and the machine is in a safe state before loading or changing tooling. Use a calibrated collet or end mill holder sized for a 3\/16 inch shank and verify runout with a dial indicator before production cuts. Do not exceed the manufacturer-recommended feeds and speeds for the workpiece material and cutting depth.\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: 0.02 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inches (0.625 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\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\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: 12181293\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743288099122,"sku":"12181293","price":33.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53bda8da6bf39a255feeb802ff9dc1de.jpg?v=1788845123","url":"https:\/\/voomisupply.com\/products\/accupro-12181293-corner-radius-end-mill-3-16in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
