It features a 0.09 mm corner radius, a 0.25 inch mill diameter, and a 0.25 inch shank diameter, making it a compact tool suited for tight-tolerance work. The AlTiN coating improves heat resistance and extends tool life in hardened materials and high-speed cutting applications. With three right-hand flutes and right-hand cutting direction, this end mill delivers smooth chip evacuation and consistent finish quality. Machinists and tool-and-die professionals install this tool in CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis corner rounding end mill is used to produce uniform, burr-free rounded edges on metal workpieces. The double-ended design provides two usable cutting ends per tool, extending the service interval between replacements. With a tip diameter of 0.06 inch and a 0.09 mm radius, it is well suited for fine edge-breaking and corner-profiling passes on ferrous and non-ferrous materials. It fits standard 1\/4 inch collets and tool holders commonly found in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-ended design provides two cutting ends per tool for extended service life\u003c\/li\u003e\n\u003cli\u003eAlTiN coating enhances heat and wear resistance in high-speed and hardened-material applications\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability under load\u003c\/li\u003e\n\u003cli\u003e0.09 mm corner radius produces precise, consistent rounded edges\u003c\/li\u003e\n\u003cli\u003eThree right-hand flutes promote efficient chip evacuation and smooth surface finish\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4 inch collet chucks and end mill holders on CNC machining centers and manual milling machines accepting 1\/4 inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or tool holder to the recommended engagement depth per the holder manufacturer guidelines. Verify cutting direction and spindle rotation are matched before initiating a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.054 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MICRO 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CRE-250-090X\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":52086718169394,"sku":"CRE-250-090X","price":110.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19dcdedf8aa309c5b7e5ce5dca894bdd.jpg?v=1790059850","url":"https:\/\/voomisupply.com\/products\/micro-100-cre-250-090x-corner-rounding-end-mill-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
