It features a 0.75-inch diameter with a matching 0.75-inch straight-cylindrical shank, a 3-inch length of cut, and a 6-inch overall length that places it in the extra-long category. The 4-flute, right-hand helical geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin carbide, this end mill delivers consistent tolerancing and dimensional stability in demanding machining environments. It is installed and used by machinists and CNC operators in job shop, production, and toolroom settings.\u003c\/p\u003e\u003cp\u003eThe 484-7500-BN is suited for milling steel, stainless steel, cast iron, non-ferrous metals, and hard materials. Its extra-long reach of 3 inches makes it applicable for deep-cavity work, contour milling, and profiling operations where standard-length tooling cannot access the workpiece geometry. The single-end, uncoated bright finish design is appropriate for general-purpose applications where coatings are not required by the material or process. This tool fits horizontal and vertical CNC machining centers as well as manual knee mills with appropriate collet or end mill holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.75-inch ball nose diameter with 0.375-inch nose radius for contour and 3D profiling work\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand helical design with 30-degree helix angle for balanced roughing and finishing\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eExtra-long 6-inch overall length with 3-inch length of cut for deep-cavity access\u003c\/li\u003e\n\u003cli\u003eCompatible with steel, stainless steel, cast iron, non-ferrous metals, and hard materials\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish; no coolant-through feature, suitable for flood or mist coolant externally applied\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-bore end mill holders and collet chucks accepting a 0.75-inch cylindrical shank.

Secure the shank fully within the holder to the recommended gauge-line depth, ensuring no less than 3 times the shank diameter is engaged in the collet or holder. Verify runout with a dial indicator before production cutting. Do not exceed the recommended depth of cut or feed rate for the workpiece material, as solid carbide tooling is brittle and susceptible to breakage under shock loading or excessive deflection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.375 inches\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\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\u003eLength Type\u003c\/strong\u003e: Extra Long\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\u003eSeries\u003c\/strong\u003e: 484BN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.16 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: 484-7500-BN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738551124274,"sku":"484-7500-BN","price":428.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c31f262fdb0d8a0f0945f023f7bb4b42_f5d2af61-711c-4c62-96dd-0ea97c549274.jpg?v=1788800917","url":"https:\/\/voomisupply.com\/products\/osg-484-7500-bn-ball-end-mill-0-75in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
