The cutter features a 5\/8-inch (0.6250-inch) mill diameter, six flutes, and a 0.0900-inch corner radius that produces a controlled edge break on finished workpiece surfaces. An AlTiN+ coating provides elevated heat resistance and surface hardness, extending tool life in high-temperature cutting applications. Variable helix and variable index geometry reduce harmonic vibration during the cut, improving surface finish and allowing higher feed rates. The primary target workpiece material is high-temp alloy (Material Code S), making this tool well suited to aerospace, power generation, and industrial component machining.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers where high-temp alloys such as nickel-base superalloys, titanium, and cobalt-chrome are the primary workpiece materials. The centercutting design allows plunge entry when required. With a 1-5\/8-inch (1.6250-inch) length of cut and a 3-1\/2-inch overall length, it handles moderate-depth pocketing, profiling, and slotting operations. The 5\/8-inch shank diameter is compatible with standard ER collet chucks and side-lock holders commonly used in production shops.\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 workpiece materials\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating delivers high oxidation resistance and hardness at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduce chatter and improve surface finish\u003c\/li\u003e\n\u003cli\u003e0.0900-inch corner radius protects the cutting edge and produces a consistent fillet on finished parts\u003c\/li\u003e\n\u003cli\u003eSix-flute configuration increases feed-per-tooth capability and improves productivity in finishing passes\u003c\/li\u003e\n\u003cli\u003eCentercutting capability supports plunge and ramp entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high-temp alloy workpiece materials (Material Code S) in CNC milling applications.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before loading or unloading the tool. Use a properly sized and balanced tool holder to maximize the benefit of the variable helix geometry. Verify runout at the tool tip with a dial indicator before production use, as excessive runout will accelerate edge wear and diminish corner radius accuracy.\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 inches)\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 inches (1.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches (3.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0900 inches\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+\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy (Code S)\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\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: 72091291\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755219157298,"sku":"72091291","price":238.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_6fd0bfc7-03e3-4caa-8484-599b84a7ba9a.jpg?v=1788952332","url":"https:\/\/voomisupply.com\/products\/accupro-72091291-corner-radius-end-mill-5-8-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
