Part of the HP441BN Hy-Pro-Carb series, it features a 0.5 inch diameter cutting edge, a 1 inch length of cut, and a 3 inch overall length. The four-flute design pairs with a 35-degree helix angle and a TiAlN PVD coating to extend tool life across a broad range of workpiece materials. The straight cylindrical shank measures 0.5 inches in diameter. Machinists and CNC operators working in job shops, aerospace, or precision manufacturing environments are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for use on steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material codes P, M, K, S, and H. The single-end, right-hand cutting and right-hand flute configuration makes it a standard choice for conventional vertical and horizontal milling centers. The submicron carbide grade and TiAlN coating make it particularly well-suited for dry or semi-dry high-speed machining where heat resistance and edge retention are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5 inch ball nose diameter with a 0.25 inch nose radius for true ball geometry\u003c\/li\u003e\n\u003cli\u003eFour helical flutes at a 35-degree medium helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating provides oxidation resistance and extended tool life at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide grade delivers rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cut with straight cylindrical shank for direct collet or chuck mounting\u003c\/li\u003e\n\u003cli\u003eRated for roughing and finishing in steel, stainless, cast iron, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on CNC milling machines and machining centers capable of accepting a 0.5 inch straight cylindrical shank.

Secure the shank in a collet, end mill holder, or hydraulic chuck rated for the shank diameter before beginning any operation. Verify spindle direction is set to right-hand rotation to match the flute orientation. Always power down and lock out the machine before changing tooling, and confirm runout is within acceptable limits after mounting to protect both the tool and the workpiece.\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\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (PVD)\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: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP441BN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HP441-5000-BN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739367178546,"sku":"HP441-5000-BN","price":159.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56432cd64a29a5f776d0271edf7a7b19_749697d2-6d04-4613-b826-533f92f1af95.jpg?v=1788813660","url":"https:\/\/voomisupply.com\/products\/osg-hp441-5000-bn-ball-end-mill-0-5in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
