Designed as a single-end, 4-flute tool with a 0.5-inch mill diameter and a 30-degree medium helix angle, it handles both roughing and finishing operations in a single tool. The extra-long 3-inch length of cut and 6-inch overall length make it well suited for deep-cavity work and extended-reach applications where shorter tools fall short. Micrograin carbide construction provides the rigidity and edge retention needed when cutting steel, stainless steel, cast iron, non-ferrous metals, and hard materials. The bright uncoated finish keeps the tool ready to use without additional prep.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard machining center and CNC mill applications in job shops, tool rooms, and production environments. The straight cylindrical 0.5-inch shank seats directly into standard ER collets, hydraulic chucks, and shrink-fit holders without adapters. Its reach length of 3.0 inches and 0.25-inch nose radius make it a practical choice for contour milling, 3D profiling, and finishing passes on molds, dies, and complex part geometry. The right-hand cut and right-hand flute direction follow standard spindle rotation, requiring no special programming adjustments on most machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention in steel, stainless, cast iron, non-ferrous, and hard materials\u003c\/li\u003e\n\u003cli\u003e4-flute, helical flute design supports both roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003eExtra-long 3-inch length of cut with 6-inch overall length for deep-cavity and extended-reach work\u003c\/li\u003e\n\u003cli\u003e30-degree medium helix angle balances chip evacuation and cutting forces across material types\u003c\/li\u003e\n\u003cli\u003e0.25-inch nose radius for smooth ball-end profiling and contour passes\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish; right-hand cut and right-hand flute direction for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with steel, stainless steel, cast iron, non-ferrous metals, and hard materials as noted in the workpiece material classifications P, M, K, N, and H.

Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before loading or changing the tool. Seat the shank fully into the toolholder to the recommended gauge line before torquing the retention mechanism to the toolholder specification. Confirm runout with a dial indicator after clamping, as excessive runout accelerates edge wear and reduces dimensional accuracy.\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\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\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\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\u003eFlute 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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 484BN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\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\u003eWeight\u003c\/strong\u003e: 0.5 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: 484-5000-BN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727184986418,"sku":"484-5000-BN","price":206.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c31f262fdb0d8a0f0945f023f7bb4b42.jpg?v=1788674452","url":"https:\/\/voomisupply.com\/products\/osg-484-5000-bn-ball-end-mill-0-5in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
