The ball nose geometry allows for contoured surface milling, 3D profiling, and slotting in a single tool. Built from micrograin solid carbide, it delivers rigidity and edge retention in demanding cuts. With a 0.25 inch diameter, 1 inch length of cut, and a 40-degree right-hand helix, this end mill is suited for high-speed finishing and semi-finishing passes where accuracy and surface finish are critical. It is sold as a single-end tool with an uncoated finish.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers, vertical mills, and manual milling setups for profiling, contouring, and pocket milling. The long flute geometry with a 1 inch length of cut and 4 inch overall length provides extended reach for deeper pockets and cavities without requiring a longer shank extension. It is a common choice for tool and die, mold making, aerospace component work, and precision job shop applications where micrograin carbide is preferred for its hardness and wear resistance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eBall nose geometry enables 3D contouring, profiling, and radius floor finishing\u003c\/li\u003e\n  \u003cli\u003e40-degree right-hand helix promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003e3-flute design balances chip clearance with rigidity for finishing passes\u003c\/li\u003e\n  \u003cli\u003eLong length configuration with 4 inch OAL for extended reach applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for dry cutting or use with cutting fluid on a wide range of materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shank ball end mill compatible with any CNC or manual milling machine spindle or collet system accepting a 0.25 inch round shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC operator using a collet, end mill holder, or shrink-fit toolholder rated for the 0.25 inch shank diameter. Ensure the spindle and toolholder are clean and free of chips before seating the end mill. Always confirm runout with a dial indicator after clamping, as excessive runout accelerates edge wear on carbide tools. Follow machine manufacturer guidelines for maximum RPM and feed rates appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 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\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eWeight\u003c\/strong\u003e: 0.14 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: 12184499\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51751113621810,"sku":"12184499","price":58.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff65cb494ce2660c0cef2b5ffdaa5222.jpg?v=1788921726","url":"https:\/\/voomisupply.com\/products\/accupro-12184499-ball-end-mill-0-25in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
