Built with a 0.1875 inch cutting diameter, a 0.3125 inch length of cut, and a 1.5 inch overall length, this end mill is designed for precision work in tight tolerances. The 38-degree helical flute geometry promotes efficient chip evacuation and smooth cutting action. A TiAlN-LT coating improves thermal resistance and extends tool life in abrasive and hard materials. Machinists and CNC operators working in job shops, production environments, and tool rooms will find this a reliable drop-in cutting tool.\u003c\/p\u003e\u003cp\u003eThe 2870200 is rated for use in steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering a broad range of common workpiece types encountered in general machining and aerospace or die-and-mold applications. The straight-cylindrical shank at 0.1875 inch diameter fits standard ER collets and end mill holders. The right-hand cut and right-hand flute direction make it compatible with conventional spindle configurations found on most vertical and horizontal machining centers. It is centercutting, allowing plunge operations where the application requires.\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\u003eTiAlN-LT coating for high-temperature performance and extended tool life\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003e4-flute design balances material removal rate with chip clearance\u003c\/li\u003e\n\u003cli\u003eCentercutting capability supports plunge, slot, and peripheral milling operations\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard collet and end mill holder systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard end mill holders and ER collet chucks accepting a 0.1875 inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet or holder runout is within acceptable limits before operation, as excessive runout accelerates wear and reduces surface finish quality. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut being applied.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.3125 inches (5\/16 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN-LT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 4V05\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: High Temperature Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.022 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: WIDIA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2870200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WIDIA","offers":[{"title":"Default Title","offer_id":67910831767858,"sku":"2870200","price":70.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7aa49b01029403705f99cfb9a82018e_374ececf-a9ba-4d4b-9c55-1568410c86b6.jpg?v=1791200552","url":"https:\/\/voomisupply.com\/products\/widia-2870200-square-end-mill-3-16-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
