Built to the HS series specification, it features a 0.125-inch (1\/8 inch) mill diameter and a 6-flute geometry with a variable helix and variable index configuration. The AlTiN+ coating delivers elevated heat resistance and tool life when cutting high-temperature alloys and other difficult workpiece materials. At 1.5 inches overall length with a 0.25-inch length of cut, this is a compact tool suited for finishing and semi-finishing operations where precision edge control and corner geometry are critical.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered primarily for high-temperature alloy (material code S) applications, including nickel-based superalloys, titanium, and similar hard-to-machine materials commonly found in aerospace, power generation, and medical component manufacturing. The single-end, center-cutting design allows plunge entry and right-hand cutting with right-hand flute direction. The 0.020-inch corner radius protects the cutting edge and reduces stress concentration at corners, extending tool life in high-load finishing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in high-temp alloys\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating for elevated thermal resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e6-flute variable helix and variable index design reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003e0.020-inch (0.51 mm) corner radius protects the cutting edge at workpiece corners\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating suited for dry or minimal-lubrication cutting strategies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in high-temperature alloy (S-material) milling applications.

Ensure the machine spindle and tool holder are clean and free of chips before seating the shank. Verify runout with a dial indicator before beginning a production cut, particularly given the small diameter. Follow the tooling manufacturer and machine builder guidelines for speeds, feeds, and depth of cut for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 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: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.020 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute 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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\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: 0.01 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: 72039969\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51751353876786,"sku":"72039969","price":42.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_d1420da1-f89b-4bcb-a730-2146d023eb59.jpg?v=1788923017","url":"https:\/\/voomisupply.com\/products\/accupro-72039969-corner-radius-end-mill-0-125-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
