It features a 1 inch cutting diameter, a 1-3\/4 inch length of cut, and a 0.06 inch corner radius that reduces stress concentration at the cutting edge and extends tool life. The AlTiN coating provides excellent heat resistance and hardness at elevated cutting temperatures. With a 40-degree helix angle and right-hand spiral flutes, this tool delivers efficient chip evacuation and smooth cutting action. It is a single-end, centercutting design, meaning it can be used for plunge cuts as well as peripheral and slot milling. Machinists and tool-and-die professionals install this tool in CNC machining centers and vertical mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finish and semi-finish milling operations where a radiused corner is required to prevent sharp inside corners on workpiece features. Typical applications include die and mold work, aerospace components, and precision part machining where corner radius tolerances are tightly controlled. The 3-flute configuration balances chip clearance with rigidity, making it effective in both roughing passes at moderate depths and finishing passes requiring tight dimensional control. The 1 inch shank diameter provides a secure, concentric grip in standard end mill holders or shrink-fit tooling systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch cutting diameter with a 0.06 inch corner radius for stress-reducing edge geometry\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for high heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003e3-flute, right-hand spiral design balances chip clearance and cutting stability\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style corner radius end mill for use in CNC machining centers, vertical mills, and other rotating spindle equipment accepting a 1 inch shank diameter tool holder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool runout and holder clamping torque. Power down and lock out the spindle before loading or unloading the tool. Verify tool projection and holder grip length prior to operation to minimize vibration and deflection. Always confirm spindle RPM and feed rate settings are appropriate for the workpiece material and coating type before starting a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/4 inches\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: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: AlTiN\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eVariable Index\u003c\/strong\u003e: No\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\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\u003eWeight\u003c\/strong\u003e: 1.34 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12181885\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729908564274,"sku":"12181885","price":466.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a6c1dc9ad7b7423d8e57a28604f3e72_a178f004-b58e-478d-ab76-ac008d2162c3.jpg?v=1788709809","url":"https:\/\/voomisupply.com\/products\/accupro-12181885-corner-radius-end-mill-1-in-3-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
