It features a 0.25-inch diameter with a 1.5-inch length of cut and a 6-inch overall length, making it suitable for deep-reach applications where a standard-length tool would fall short. The TiAlN PVD coating delivers thermal resistance and extended edge life under high cutting loads. The eccentric relief geometry increases cutting edge stability, supports long tool life, and reduces reconditioning cost by easing regrinding. With a 0.125-inch nose radius and right-hand helical flutes at a 30-degree helix angle, this tool handles both roughing and finishing passes.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills where long-reach ball profiling is required. The 6-inch OAL with a 0.25-inch straight-cylindrical shank allows access into deeper cavities and complex contoured surfaces. The center-cutting design supports plunging and ramping entry, making it practical for 3D contouring and die or mold work. It is a single-end configuration intended for professional machinists running production or job-shop operations in steel and stainless applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating rated for steel, stainless steel, and cast iron applications\u003c\/li\u003e\n\u003cli\u003eEccentric relief geometry extends cutting edge stability and tool life\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design supports plunging, ramping, and 3D contouring\u003c\/li\u003e\n\u003cli\u003eLong series length at 6 inches OAL with 1.5-inch reach length for deep-cavity access\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand helix, 30-degree medium helix angle for controlled chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and conventional mills with standard straight-cylindrical 0.25-inch shank collet or end mill holders.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank in a properly sized collet or end mill holder with sufficient clamping engagement to prevent pull-out under cutting loads. Verify runout with a dial indicator before production cuts, as runout directly affects surface finish and tool life with ball end mills.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00031 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: GOmill 4BN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Catalog Number\u003c\/strong\u003e: 4BN0250IX150A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.154 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5824523\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733223899442,"sku":"5824523","price":96.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7eb984bc37c1fd40c6f6160fdee41a85_9340f7fc-f706-4804-b749-a1cf009108a5.jpg?v=1788752978","url":"https:\/\/voomisupply.com\/products\/kennametal-5824523-ball-end-mill-0-25-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
