It features a 3\/16 inch (0.1875 inch) mill diameter with a 0.03 inch corner radius, producing a controlled blend between the end face and the flute cutting edge. With a 40-degree helix angle and AlTiN coating, it handles elevated cutting speeds while maintaining edge integrity on ferrous and non-ferrous workpiece materials. The micrograin carbide substrate contributes to rigidity and wear resistance. This tool is suited for CNC machining centers and manual mills where close-tolerance profiling, slotting, or pocket milling is required.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in job shops, tool rooms, and production machining environments. The centercutting geometry allows both plunge and ramp entry, making it practical for die and mold work, contour profiling, and multi-axis finishing passes. The 5\/8 inch length of cut and 2 inch overall length fit short-reach setups where rigidity is a priority. The 3\/16 inch shank diameter matches the mill diameter, suiting it for standard collets in that size range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and extended tool life\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating supports elevated cutting temperatures and reduces built-up edge\u003c\/li\u003e\n  \u003cli\u003e0.03 inch corner radius blends end and side cutting edges to reduce stress concentration in machined corners\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits plunge, ramp, and helical entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute spiral for conventional CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill for use in standard 3\/16 inch collets on CNC machining centers, vertical mills, and compatible toolholding systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully in a clean, undamaged collet or toolholder and torque the retention nut to the toolholder specification. Verify runout with an indicator before beginning cuts, as excessive runout accelerates corner radius wear and reduces dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inches (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\u003eShank Diameter\u003c\/strong\u003e: 3\/16 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\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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 End\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 (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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: 0.06 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12181308\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739788575026,"sku":"12181308","price":42.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3346c5258aef3c09883233c5970ad6dc.jpg?v=1788818881","url":"https:\/\/voomisupply.com\/products\/accupro-12181308-corner-radius-end-mill-3-16-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
