It features a 3\/16 inch diameter, a 0.02 inch corner radius, and a TiCN (titanium carbonitride) coating that improves wear resistance and tool life compared to uncoated carbide. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. With four flutes and a single-end, centercutting design, this end mill handles slotting, profiling, and plunge operations. Machinists and tool-and-die professionals working with CNC machining centers or manual knee mills are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on steel, stainless steel, cast iron, and similar materials where a corner radius is required to reduce stress concentrations or meet part geometry tolerances. It fits typical applications in mold making, die work, and precision component machining. The 5\/8 inch length of cut and 2 inch overall length make it appropriate for shallow-to-moderate depth profiling and finishing passes in tight workpiece features.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating provides increased surface hardness and reduced friction for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003e0.02 inch corner radius reduces edge chipping and stress concentrations at part corners\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers rigidity and resistance to deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and right-hand cutting for standard CNC and manual mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill for use in standard 3\/16 inch collets or end mill holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist. Secure the shank fully into a compatible 3\/16 inch collet or end mill holder, ensuring the tool is held to the recommended engagement depth per the toolholder manufacturer. Inspect the tool and holder for runout before cutting, as excessive runout accelerates edge wear and degrades surface finish. Do not exceed the tool's rated depth of cut or feed parameters for the workpiece material.\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\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.02 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 12182422\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738609811762,"sku":"12182422","price":34.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/711dcf9f3cae1d31c3f05538d524ef86.jpg?v=1788801719","url":"https:\/\/voomisupply.com\/products\/accupro-12182422-corner-radius-end-mill-3-16-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
