It carries a 5\/8-inch (0.6250 inch) mill diameter, six flutes, and a 0.0300-inch corner radius that protects the cutting edge while producing a controlled blend between the floor and wall of a milled feature. The AlTiN plus coating provides elevated heat resistance, making this tool well-suited for the elevated cutting temperatures generated in aerospace, power generation, and precision machining environments. Variable helix and variable index geometry reduce harmonic chatter, improving surface finish and extending tool life in difficult cuts.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers where high-temp alloys such as Inconel, titanium, and similar materials are being profiled, slotted, or finish-milled. The 1-5\/8-inch length of cut and 3-1\/2-inch overall length accommodate standard depth-of-cut requirements in aerospace component work and job-shop precision milling. The right-hand flute direction and right-hand cutting direction are compatible with standard spindle rotation on vertical and horizontal machining centers. Centercutting capability allows plunge entry without a pre-drilled pilot hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN plus coating for high heat resistance during dry or near-dry machining of high-temp alloys\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduce chatter and improve surface finish\u003c\/li\u003e\n\u003cli\u003e0.0300-inch (0.76 mm) corner radius protects the cutting edge and blends floor-to-wall transitions\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge entry\u003c\/li\u003e\n\u003cli\u003eSix-flute configuration increases feed rate capability and improves finish on finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers with a 5\/8-inch tool holder or collet. Primary workpiece material designation is high-temp alloy (material code S), covering nickel-based superalloys, titanium alloys, and similar difficult-to-machine materials.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool should be installed and removed by a qualified machinist or CNC setup technician using a torque-rated toolholder and collet appropriate for the 5\/8-inch shank diameter. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Confirm runout at the toolholder before cutting, as excessive runout accelerates edge wear and can cause premature tool failure in high-temp alloy applications. Follow the machine tool manufacturer and cutting tool manufacturer feed and speed recommendations for the specific workpiece material and depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inch \/ 15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inch (1.6250 inch \/ 41.28 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inch (3.5000 inch \/ 88.90 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inch \/ 15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inch (0.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN Plus\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\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy (Code S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.47 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: 72090509\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753341845810,"sku":"72090509","price":238.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_b8cf8f87-b72a-4304-acfd-57af7d687cd5.jpg?v=1788935623","url":"https:\/\/voomisupply.com\/products\/accupro-72090509-corner-radius-end-mill-5-8-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
