With a 0.125-inch mill diameter, a 0.25-inch length of cut, and a 1.5-inch overall length, this tool handles both roughing and finishing passes in a single-end configuration. The micrograin carbide substrate delivers consistent edge integrity and dimensional stability under cutting loads. A 30-degree medium helix angle promotes efficient chip evacuation while maintaining surface finish quality. The bright uncoated finish makes it suitable for applications where coating interaction with the workpiece material is a concern.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for machining steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It fits standard CNC machining centers, manual knee mills, and Swiss-style lathes equipped with live tooling. The 0.125-inch straight-cylindrical shank seats directly into ER collet chucks or precision end mill holders. It is a standard-length tool appropriate for general-purpose cavities, contours, and profiling operations where extended reach is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for consistent tolerancing and edge durability\u003c\/li\u003e\n\u003cli\u003e0.0625-inch nose radius for true ball-end profiling and 3D contouring\u003c\/li\u003e\n\u003cli\u003e30-degree medium helix angle for balanced chip flow in both roughing and finishing\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for non-ferrous metals and applications where coatings are undesirable\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of plus 0.0000 \/ minus 0.0020 inches for repeatable fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials per OSG material codes P, M, K, N, S, and H.

Verify that the collet or tool holder is clean and free of debris before seating the shank, and confirm runout with a dial indicator before production use. Power down the spindle and engage machine lockout before changing tooling. Do not exceed the recommended length of cut of 0.25 inches to avoid tool deflection or breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0625 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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0000 \/ minus 0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: plus 0.0000 \/ minus 0.0005 inches\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: 412BN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 412-1250-BN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737571787058,"sku":"412-1250-BN","price":24.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebc575ff0cf6afffd57d4e58388bd8d2.jpg?v=1788790625","url":"https:\/\/voomisupply.com\/products\/osg-412-1250-bn-ball-end-mill-0-125-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
