Built from solid carbide and coated with AlTiCrN, it delivers high heat resistance and extended tool life in demanding cutting conditions. The 3\/16 inch (0.1875 inch) diameter, 4-flute geometry, and variable index design help reduce chatter and improve surface finish. With a length of cut of 0.1600 inches and a 0.2500 inch neck length, this end mill suits tight-tolerance profiling, slotting, and finishing passes where precision is critical. Machinists and toolroom professionals are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual milling machines handling ferrous and non-ferrous metals, hardened steels, and similar workpiece materials. The AlTiCrN coating makes it well-suited for dry or minimum-quantity lubrication cutting environments. Its 3\/16 inch shank diameter fits standard collets and tool holders of the same bore size. The 2 inch overall length provides adequate reach for most production milling setups without sacrificing rigidity in the spindle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiCrN coating provides high-temperature oxidation resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter during cutting\u003c\/li\u003e\n\u003cli\u003e4-flute design supports higher feed rates and improved surface finish\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 0.1600 inch length of cut for precision profiling and finishing\u003c\/li\u003e\n\u003cli\u003e0.2500 inch neck length allows access to features with mild depth requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide ball end mill compatible with standard 3\/16 inch bore collets, end mill holders, and shrink-fit tooling systems used in CNC and manual milling operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician familiar with end mill setup procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the correct insertion depth per the tool holder manufacturer guidelines and verify runout with a dial indicator before cutting. Always match spindle speed and feed rate to the workpiece material and coating recommendations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003c\/strong\u003e: AlTiCrN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.034 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 39917372\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737091080498,"sku":"39917372","price":77.77,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b38a1cd685c5fa6289f89c55c587452d.jpg?v=1788784117","url":"https:\/\/voomisupply.com\/products\/accupro-39917372-ball-end-mill-3-16-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
