It has a 0.1562-inch mill diameter, a 0.01-inch corner radius, and five flutes with a right-hand spiral and right-hand cutting direction. The tool is coated with AlTiN (aluminum titanium nitride) for heat resistance and extended tool life at higher cutting speeds. It measures 2 inches in overall length with a 0.5-inch length of cut and a 3\/16-inch shank diameter. Variable index flute spacing helps reduce chatter and improve surface finish. This is a single-end, center-cutting tool made from micrograin carbide stock.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finishing and semi-finishing operations in hardened steels, stainless steel, cast iron, and high-temperature alloys. The AlTiN coating makes it a practical choice for dry or minimal-lubrication machining environments where heat buildup is a concern. Machinists use it in CNC machining centers for contouring, slotting, and profiling where a small corner radius is required to reduce stress concentrations on the workpiece. Its 0.1562-inch diameter makes it well-suited for tight-tolerance cavities and detailed features in die and mold work or precision component machining.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.01-inch corner radius reduces stress concentrations and extends workpiece life\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides thermal resistance for high-speed and dry machining\u003c\/li\u003e\n\u003cli\u003e5-flute variable index design reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral for standard CNC milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide end mill for use in CNC machining centers and manual mills accepting a 3\/16-inch straight shank tool holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with tool holding systems and CNC setup procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or end mill holder to the recommended engagement depth before tightening. Verify runout with a dial indicator after installation, as excessive runout will accelerate wear on a fine-diameter tool of this type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1562 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 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\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\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\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 12178637\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729192747314,"sku":"12178637","price":37.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d553127a40c0ff7301557d33db8560c2.jpg?v=1788701741","url":"https:\/\/voomisupply.com\/products\/accupro-12178637-corner-radius-end-mill-0-1562-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
