With a 0.4531-inch mill diameter and a 1-inch length of cut, this single-end tool delivers precise material removal in ferrous and non-ferrous metals, hardened steels, and engineering plastics. The 4-flute configuration paired with a 40-degree helix angle promotes chip evacuation and surface finish quality. Micrograin carbide construction gives the tool durability and edge retention under demanding cutting conditions. Installed by machinists and tool-and-die professionals in CNC milling operations.\u003c\/p\u003e\u003cp\u003eThis ball end mill is suited for finish and semi-finish milling passes on contoured workpieces, pockets, and sculptured surfaces. The 0.4531-inch diameter makes it a practical choice for detailed profiling work where a standard 7\/16-inch tool is too small and a 1\/2-inch tool creates interference. The right-hand cut and right-hand spiral flute direction are standard for most CNC vertical and horizontal machining centers. A 3-inch overall length and 1\/2-inch shank diameter allow secure toolholder engagement with minimal overhang for typical job-shop setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for extended tool life and edge stability\u003c\/li\u003e\n\u003cli\u003e4-flute design with 40-degree helix angle for improved chip flow and finish quality\u003c\/li\u003e\n\u003cli\u003eBall end geometry enables 3D profiling, contouring, and curved surface milling\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for a wide range of workpiece materials and cutting fluids\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral — compatible with standard CNC mill spindle rotation\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 to -0.002 inches for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 1\/2-inch straight shank toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Secure the shank in a collet chuck or end mill holder to the toolholder manufacturer's specified engagement depth before tightening. Confirm spindle direction is set to right-hand rotation before initiating a cut. Inspect the cutting edges for chipping or wear before each use; a damaged ball end mill can compromise part geometry and workpiece surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.4531 inches (29\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 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\/Finish\u003c\/strong\u003e: Uncoated\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.002 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\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\u003eChipbreaker\u003c\/strong\u003e: No\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: 12184670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733267382578,"sku":"12184670","price":99.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/55f019bc8a79e25b3272263466e878b2.jpg?v=1788753425","url":"https:\/\/voomisupply.com\/products\/accupro-12184670-ball-end-mill-0-4531-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
