It features a 3\/4-inch mill diameter, six flutes, and a 1.25-inch length of cut, making it well-suited for aggressive material removal with a controlled corner profile. The 0.190-inch corner radius reduces stress concentration at cutting edges and extends tool life in interrupted cuts. An AlTiN+ coating provides thermal resistance and hardness at elevated cutting temperatures. Variable helix and variable index geometry help suppress chatter and improve surface finish in difficult-to-machine materials.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers handling high-temp alloys such as nickel, titanium, and cobalt-based materials, which fall under the S-category workpiece classification. It is a single-end tool with a 3\/4-inch shank diameter and an overall length of 4 inches. The center-cutting design allows plunge entry when needed. Right-hand flute direction and right-hand cutting direction are standard for conventional CNC spindle setups. It is suited for aerospace, power generation, and precision industrial machining operations where tool life and edge stability in superalloys are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN+ coating for high-heat resistance and extended tool life in superalloy cutting\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduce chatter and improve surface finish\u003c\/li\u003e\n\u003cli\u003e0.190-inch corner radius minimizes edge chipping and stress at the cutting corner\u003c\/li\u003e\n\u003cli\u003eSix-flute configuration increases feed rate capability and material removal rate\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable for plunge milling applications\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and dimensional stability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for CNC milling applications involving high-temperature alloys (S-category materials).

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Use a properly sized and balanced tool holder to minimize runout, which is critical when machining high-temp alloys with tight tolerances. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and coolant application appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches (19.05 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: 1.250 inches (31.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.000 inches (101.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.190 inches (4.82 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+\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\u003eCenter Cutting\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 (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: 0.77 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: 72030141\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733188772146,"sku":"72030141","price":308.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_80da18fd-7402-46b4-be83-8562c2a111eb.jpg?v=1788752512","url":"https:\/\/voomisupply.com\/products\/accupro-72030141-corner-radius-end-mill-3-4-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
