Built to Series 857 standards, this stub-length tool features a 0.09-inch mill diameter, a 0.1350-inch length of cut, and a 0.0450-inch nose radius that produces accurate ball-nose profiles for contoured surfaces and pocket finishing. The 2-flute, right-hand spiral geometry with a variable helix angle between 35 and 40 degrees supports both roughing and finishing passes. The bright, uncoated finish allows for straightforward visual inspection of tool condition during service intervals. Licensed machinists and toolroom operators typically spec this tool for close-tolerance work on small-diameter features.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, aluminum and other non-ferrous materials, high-temperature alloys, and hardened materials. The single-end, straight-cylindrical shank with a 3\/16-inch (0.1875-inch decimal) diameter fits standard collet chucks and tool holders found on CNC machining centers, manual mills, and die-sinking setups where small-diameter ball profiles are required. The stub-length configuration provides added rigidity, reducing deflection during aggressive cuts in confined cavities or near-net-shape finishing work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction supports elevated cutting temperatures and improved wear resistance over high-speed steel\u003c\/li\u003e\n  \u003cli\u003eVariable helix angle (35 to 40 degrees) reduces harmonics and chatter during both roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry into the workpiece without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with a wide range of cutting fluids and coolant strategies\u003c\/li\u003e\n  \u003cli\u003eStub-length geometry maximizes rigidity in short-reach milling applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-application cobalt ball end mill for use on steel, stainless steel, cast iron, aluminum and non-ferrous metals, high-temperature alloys, and hardened materials in standard collet or tool holder systems accepting a 3\/16-inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify collet size matches the 0.1875-inch shank diameter and torque the collet nut per the tool holder manufacturer's specifications. Confirm runout is within acceptable tolerance before commencing the cut, particularly given the small mill diameter where even minor runout can affect surface finish and tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0900 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1350 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0450 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 to 40 degrees (Variable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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 \/ -0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 857\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 934-000-241\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689420816690,"sku":"934-000-241","price":34.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1312f55ce9b0003d1839d1f1075c5555.jpg?v=1788259235","url":"https:\/\/voomisupply.com\/products\/value-collection-934-000-241-ball-end-mill-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
