The set includes both 2-flute and 4-flute end mills, making it suitable for slotting, profiling, and general-purpose milling operations on a wide range of materials. The TiN coating increases surface hardness and reduces friction at the cutting edge, extending tool life compared to uncoated high-speed steel. Machinists and toolroom technicians working on manual mills or CNC knee mills rely on this type of set for day-to-day cutting work across steel, aluminum, and similar materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill set is suited for job shops, maintenance machining, and light production environments where a range of common fractional diameters is needed on hand. The inclusion of both 2-flute and 4-flute geometry in a single set allows the user to select the correct tool for the material and operation without maintaining two separate inventories. Two-flute end mills are preferred for softer materials and slotting, while the 4-flute versions are better suited for finishing cuts in ferrous metals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20-piece set covering 3\/16 inch through 3\/4 inch in 1\/16-inch increments\u003c\/li\u003e\n  \u003cli\u003eTiN coating for improved wear resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eIncludes both 2-flute and 4-flute single end mills in each size\u003c\/li\u003e\n  \u003cli\u003eSingle end configuration for standard milling and profiling applications\u003c\/li\u003e\n  \u003cli\u003eFractional sizing covers the most commonly specified diameters in general machining\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard vertical milling machines and CNC knee mills accepting straight-shank end mills with collet or end mill holders sized to match each included diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eEnd mills should be installed by a qualified machinist using the appropriate collet or end mill holder sized to the shank diameter. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the end mill to the recommended engagement depth in the holder to prevent pullout under cutting loads. Inspect the TiN coating and cutting edges for chipping or wear before each use and replace any damaged tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePiece Count\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Range\u003c\/strong\u003e: 3\/16 inch to 3\/4 inch by 1\/16-inch increments\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Configuration\u003c\/strong\u003e: 2-flute and 4-flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single end\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: JET\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 650211\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JET","offers":[{"title":"Default Title","offer_id":51342933983538,"sku":"650211","price":322.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310501046.jpg?v=1782011074","url":"https:\/\/voomisupply.com\/products\/jet-650211-tin-coated-end-mill-set-20-piece-3-16-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
