Built from micrograin carbide and coated with AlTiN (aluminum titanium nitride), this tool handles elevated cutting temperatures and extends tool life in demanding applications. The 0.015-inch corner radius reduces stress concentration at the cutting edge, helping prevent chipping during aggressive passes. With a 4-flute, right-hand spiral configuration and a 40-degree helix angle, it delivers efficient chip evacuation and a smooth surface finish. This is a single-end, centercutting tool, meaning it can plunge directly into material as well as perform conventional peripheral milling.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits CNC machining centers and manual mills in job shops, tool rooms, and production environments. It is well suited for profiling, slotting, and finishing operations on steel, stainless steel, titanium, and other tough alloys. The 1\/2-inch shank diameter fits standard ER and side-lock toolholders commonly found in vertical and horizontal machining centers. The 1-inch length of cut and 3-inch overall length make it appropriate for moderate-depth cavity work and shoulder milling where rigidity is a priority.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides thermal barrier, extending tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e0.015-inch corner radius reduces edge chipping and improves corner strength\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth cutting action and efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction and right-hand cutting for standard CNC spindle operation\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 suitable for use in standard 1\/2-inch toolholders on CNC machining centers and manual knee mills performing ferrous and non-ferrous milling operations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the control is in a safe state before loading or unloading the tool. Seat the shank to the full recommended grip length in the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates tool wear and degrades surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 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 Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 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: 0.25 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: 12182607\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739240923442,"sku":"12182607","price":105.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/133aacfb8729ab90ccf947c165869807.jpg?v=1788811960","url":"https:\/\/voomisupply.com\/products\/accupro-12182607-corner-radius-end-mill-1-2-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
