With a 0.25-inch mill diameter, six flutes, and a 0.03-inch corner radius, it delivers smooth finishes and extended tool life on difficult workpieces. The AlTiN+ coating provides thermal resistance and hardness, making this end mill well-suited for cutting high-temperature alloys and other hard materials. It is a single-end, center-cutting tool with right-hand flute direction and right-hand cutting direction. Variable index and variable helix geometry help reduce harmonic chatter during aggressive cuts.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC milling operations where tight tolerances and surface quality matter. Its primary design target is high-temp alloys (material code S), including nickel-based, cobalt-based, and titanium alloys commonly found in aerospace and industrial component machining. The 1-inch length of cut and 3-inch overall length suit it to standard depth profiling, slotting, and finishing passes. Machinists and CNC programmers working in job shops, aerospace suppliers, and precision manufacturing facilities will find this tool appropriate for production and prototype work alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN+ coating for elevated heat resistance and reduced tool wear in hard materials\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eSix-flute design increases feed rate capability compared to four-flute alternatives\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003e0.03-inch corner radius protects cutting edge and reduces stress concentration at corners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4-inch collets, end mill holders, and shrink-fit tooling systems.

Ensure the tool holder and collet are clean and free of debris before seating the shank. Verify spindle runout meets the tolerance requirements of the application before beginning a cut. Follow machine tool manufacturer guidelines for pull-out force and clamping torque specific to your holder type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (6.35 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 inch (25.4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches (76.2 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches (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+\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy\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: 0.07 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: 72055080\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755797348658,"sku":"72055080","price":78.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_8b85cd1e-836c-486c-88d0-759158790476.jpg?v=1788959823","url":"https:\/\/voomisupply.com\/products\/accupro-72055080-corner-radius-end-mill-1-4-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
