It features a 0.375-inch (3\/8 inch) mill diameter, six flutes, and a 1.75-inch length of cut. The AlTiN+ coating provides thermal resistance and extended tool life when cutting high-temperature alloys and other hard materials. With a variable helix and variable index geometry, the tool reduces harmonic vibration during aggressive cuts. It is center-cutting and right-hand flute with right-hand cutting direction, making it suitable for plunge, slot, and profile operations. Machinists and CNC operators in aerospace, medical, and general machining environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where tight tolerances and smooth surface finishes are required. Its primary workpiece material designation is high-temperature alloy (material code S), covering nickel-based, cobalt-based, and titanium alloys. The 0.030-inch (0.76 mm) corner radius protects the cutting edge from chipping at the corner and produces a small radius blend at the floor of a pocket or profile. The 3\/8-inch shank diameter fits standard ER and shrink-fit toolholders common in production environments.\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+ coating for high heat resistance and extended tool life in high-temp alloys\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry to reduce chatter and improve surface finish\u003c\/li\u003e\n\u003cli\u003e0.030-inch corner radius reduces corner chipping and produces a blended floor radius\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eSix-flute configuration supports higher feed rates in finishing and semi-finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers with standard 3\/8-inch ER collet, shrink-fit, or hydraulic toolholders.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully and evenly in the toolholder to the recommended gauge-line depth and torque the collet nut per the toolholder manufacturer specifications. Verify runout at the tool tip with a dial indicator before beginning a production cut, as excessive runout will accelerate wear on a six-flute carbide tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (9.53 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: 1.75 inches (44.45 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0 inches (101.6 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.030 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 (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: 0.21 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: 72080070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748317987122,"sku":"72080070","price":88.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_622c42a2-71ba-4d26-8d59-c4b0cd65993b.jpg?v=1788892363","url":"https:\/\/voomisupply.com\/products\/accupro-72080070-corner-radius-end-mill-0-375-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
