It features a 1-inch cutting diameter, a 0.06-inch corner radius, and 5 flutes with a right-hand spiral and right-hand cutting direction. The 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. The AlTiN coating provides thermal resistance and extended tool life in dry or high-speed cutting conditions. This is a single-end, centercutting tool, meaning it can be used for plunge cuts as well as peripheral milling. It is intended for use by experienced machinists and toolroom professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits production and job-shop environments where corner-radius geometry is required to reduce stress concentrations and produce blended floor-to-wall transitions. The 1-3\/4-inch length of cut (1.125 inches decimal) and 4-inch overall length make it appropriate for moderate-depth pockets, slots, and profiling operations on vertical mills and CNC machining centers. The micrograin carbide substrate supports rigidity and edge retention at elevated cutting speeds. Variable index flute spacing helps reduce harmonic chatter during extended cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.06-inch corner radius reduces stress risers and improves workpiece surface finish at floor-to-wall junctions\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides oxidation resistance and thermal hardness for dry and high-speed milling\u003c\/li\u003e\n  \u003cli\u003e5-flute variable-index design reduces chatter and improves feed rate capability\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth chip flow and efficient cutting action\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers rigidity and edge retention in demanding materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill for use in standard 1-inch collet or end-mill-holder tooling on CNC machining centers and manual vertical mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist. Secure the 1-inch shank in a properly sized collet, shrink-fit holder, or set-screw end mill holder, ensuring full shank engagement to the recommended grip depth. Confirm runout with a dial indicator before beginning a cut. Do not exceed the recommended length-of-cut depth per pass without verifying workpiece fixturing rigidity and spindle horsepower.\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\u003eCorner Radius\u003c\/strong\u003e: 0.06 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: 1.125 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\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\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.0015 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 12180998\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749220221234,"sku":"12180998","price":513.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/492048aa1468da276bba37788785bdf2_6f99fe6d-fadf-470b-9e62-c9587bbf1fc6.jpg?v=1788903298","url":"https:\/\/voomisupply.com\/products\/accupro-12180998-corner-radius-end-mill-1-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
