With a 10 mm (0.3937 inches) mill diameter and a 22 mm length of cut, it handles both roughing and finishing operations in a single tool. The TiAlN PVD coating provides thermal and wear resistance suited to demanding ferrous machining environments. Eccentric relief ground into the cutting geometry increases edge stability, extending tool life and maintaining surface quality across extended run times. The straight cylindrical shank follows DIN 6527 standards, making it compatible with standard collet and hydraulic toolholding systems.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for use on CNC machining centers and milling machines where ferrous workpiece materials are the primary substrate. Its GOmill 4BN series geometry targets steel (ISO P), stainless steel (ISO M), and cast iron (ISO K) applications in both roughing and finishing passes. The 30-degree helix angle provides smooth chip evacuation and balanced cutting forces. At 72 mm overall length with no extended neck, this is a standard-reach tool suited for open-pocket and general-profile milling operations where clearance is not a limiting factor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN PVD coating for thermal resistance and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eEccentric relief grinding improves cutting edge stability and surface finish quality\u003c\/li\u003e\n  \u003cli\u003e4-flute helical geometry supports both roughing and finishing in a single setup\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank per DIN 6527 for broad toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle use\u003c\/li\u003e\n  \u003cli\u003eNo chipbreaker, no variable helix — consistent geometry optimized for clean finishes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard straight-bore collet chucks, shrink-fit holders, and hydraulic chucks accepting a 10 mm shank diameter.

Ensure the machine spindle is fully stopped and the toolchanger is disabled before changing tooling. Verify shank runout and holding torque per the toolholder manufacturer specifications before cutting. Observe the shank diameter tolerance of +0.000\/-0.009 mm when selecting a collet or bore size to maintain concentricity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8661 inches (22 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.8346 inches (72 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 5 mm\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\u003c\/strong\u003e: TiAlN (PVD)\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 (DIN 6527)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.025\/-0.047 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.000\/-0.009 mm\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: GOmill 4BN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.159 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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5824925\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727616049458,"sku":"5824925","price":146.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d58b919621d2b2287e925ce0df62bfef.jpg?v=1788680073","url":"https:\/\/voomisupply.com\/products\/kennametal-5824925-ball-end-mill-0-3937-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
