With a 3\/16 inch (0.1875 inch) mill diameter and a 0.045 inch corner radius, this tool reduces stress concentrations at the cutting edge and extends tool life in demanding applications. The TiCN coating improves surface hardness and wear resistance compared to uncoated carbide. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Machinists and toolroom operators working with steel, stainless, cast iron, and similar materials will find this end mill well-suited to finishing and semi-finishing passes.\u003c\/p\u003e\u003cp\u003eThis end mill is sized for light to medium material removal in CNC machining centers and manual mills. The 1 inch length of cut and 4 inch overall length suit it to applications requiring moderate reach without sacrificing rigidity. The single-end, centercutting configuration allows for both peripheral and plunge cutting. The micrograin carbide substrate supports the tight tolerances required in die and mold work, aerospace components, and general precision part production where corner radii must be held consistently.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiCN coating for improved wear resistance and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003e0.045 inch corner radius reduces edge chipping and workpiece stress risers\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute spiral for standard CNC and manual mill use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill compatible with standard 3\/16 inch collets, ER collet chucks, and end mill holders used in 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 or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 3\/16 inch shank fully into the collet or holder and torque the retention mechanism to the machine manufacturer's specification. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate wear and compromise corner radius tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.045 inch\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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 12183462\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734956867890,"sku":"12183462","price":67.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c11cdc5328202c8fa4c3155ea8e843f0.jpg?v=1788768544","url":"https:\/\/voomisupply.com\/products\/accupro-12183462-corner-radius-end-mill-3-16-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
