Built from solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness and heat resistance suited for high-speed cutting in ferrous and non-ferrous materials. The 0.085-inch corner radius and 0.25-inch mill diameter make it well-suited for fine detail work where edge geometry must be held to close tolerances. Two right-hand flutes provide efficient chip evacuation while the double-end configuration extends tool life by offering a second usable end.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC milling and manual milling applications where a controlled corner radius is required on part edges. Typical applications include deburring, edge prep, and profile finishing in job shops, production machining, and tool-and-die environments. The 1\/4-inch shank diameter fits standard collets and end mill holders commonly found on vertical machining centers and benchtop mills. The AlTiN coating makes it especially effective in dry or semi-dry cutting conditions at elevated surface speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and extends tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two cutting ends, maximizing value per tool\u003c\/li\u003e\n\u003cli\u003e0.085-inch corner radius produces consistent, repeatable edge profiles\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute geometry for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003e0.080-inch tip diameter enables access to tight-radius features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4-inch collets and end mill holders on CNC vertical machining centers and manual milling machines requiring corner rounding operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eTool installation should be performed by a qualified machinist following the machine tool manufacturer's runout and torque specifications for the collet or holder in use. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Inspect the collet bore and tool shank for chips or contamination before seating the tool. Verify corner radius and tip diameter are appropriate for the programmed toolpath before cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.085 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.080 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\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\u003eSingle or Double End\u003c\/strong\u003e: Double\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: 12180338\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750577045810,"sku":"12180338","price":81.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab05bbcd8d1658fd8aa4fb0bb8110692.jpg?v=1788916913","url":"https:\/\/voomisupply.com\/products\/accupro-12180338-corner-rounding-end-mill-1-4-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
