With a 0.5 inch cutting diameter and a 1 inch length of cut, this single-end tool features a 2-flute, right-hand helical geometry at a 30-degree helix angle. The micrograin carbide construction provides the rigidity and edge retention needed for both roughing and finishing passes. The bright uncoated finish suits applications where coating interaction with the workpiece is a concern. Machinists and tool-and-die professionals rely on this geometry for contoured surface work, 3D profiling, and radius slot milling.\u003c\/p\u003e\u003cp\u003eThe 402-5000-BN is suited for use in vertical machining centers and CNC milling machines handling a broad range of workpiece materials. Rated secondary workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The straight-cylindrical shank measures 0.5 inches in diameter and seats directly into standard ER or end mill holders. At 3 inches overall length with a standard length classification, this tool fits typical production setups without requiring extended-reach tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge retention in demanding materials\u003c\/li\u003e\n\u003cli\u003e2-flute right-hand helical geometry at 30-degree helix angle supports chip evacuation during roughing and finishing\u003c\/li\u003e\n\u003cli\u003eBall nose profile with 0.25 inch nose radius enables contoured and 3D surface milling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish for compatibility across a wide material range\u003c\/li\u003e\n\u003cli\u003eSingle-end design with straight-cylindrical shank for standard collet and end mill holder fitment\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker, no variable helix, no coolant-through — optimized for straightforward CNC milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use on steel (P), stainless steel (M), cast iron (K), non-ferrous metals (N), superalloys and titanium (S), and hard materials (H) per ISO workpiece material classification.

Seat the straight-cylindrical shank fully into the holder before torquing the retention mechanism per the holder manufacturer's specifications. Verify runout with a dial indicator before initiating a cut. Confirm that programmed feeds, speeds, and depth of cut are appropriate for the workpiece material and machine rigidity before running the first pass.\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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: +0.0000\/-0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 402BN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 402-5000-BN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747812933938,"sku":"402-5000-BN","price":89.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13264e1cd9069aa28ee37d4db0c3248e.jpg?v=1788885780","url":"https:\/\/voomisupply.com\/products\/osg-402-5000-bn-ball-end-mill-0-5in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
