With a 0.5-inch mill diameter and a 1-inch length of cut, this tool delivers aggressive material removal with tight dimensional control. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces across a wide range of workpiece materials. Four flutes provide a balance of rigidity and feed rate capability. The double-end configuration doubles usable tool life, making it a practical choice for high-volume machining environments. Machinists and toolroom operators rely on this geometry for finish passes and semi-finish contouring on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis ball end mill is suited for milling operations on ferrous and non-ferrous metals, plastics, and composites in both job shop and production settings. The uncoated solid carbide construction makes it appropriate for applications where coating compatibility or re-grinding without coating removal is a consideration. The right-hand cutting and right-hand flute direction are standard for conventional CNC vertical and horizontal milling setups. The 4-inch overall length provides sufficient reach for most standard fixturing arrangements without excessive overhang.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5-inch ball end diameter for precise contour and profile milling\u003c\/li\u003e\n\u003cli\u003e4-flute design balances chip clearance and surface finish quality\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduces chatter\u003c\/li\u003e\n\u003cli\u003eDouble-end configuration extends tool life by providing two usable cutting ends\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for applications requiring bare carbide substrate\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank replacement or new-application ball end mill for CNC and manual milling machines accepting a 0.5-inch shank diameter via collet, end mill holder, or shrink-fit tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down or in a safe state before changing tooling. Secure the 0.5-inch shank in a properly sized collet or end mill holder, torqued to the toolholder manufacturer specification. Inspect the cutting edges and shank for runout before commencing the cut, as excessive runout will accelerate wear and reduce surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\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\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Double\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\u003eVariable Helix\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\u003eExtended Reach\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: 12185322\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728451338546,"sku":"12185322","price":189.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36a86068e3a01fc49e8566d7aa4481bc.jpg?v=1788691389","url":"https:\/\/voomisupply.com\/products\/accupro-12185322-ball-end-mill-0-5-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
