With a 4.00 mm (0.1575 inch) mill diameter and a 30-degree medium helix angle, it delivers controlled chip evacuation and consistent surface finish in demanding applications. The extended long-neck geometry features a 3.85 mm neck diameter and 16.80 mm neck length, providing clearance for deep-pocket and cavity work without sacrificing rigidity. A DUROREY PVD coating reduces heat buildup and extends tool life when cutting ferrous and hard-alloy workpieces. This tool is intended for use by machinists and tool-and-die professionals running CNC milling operations.\u003c\/p\u003e\u003cp\u003eThe OSG 3056333 is designed for roughing and finishing operations in hard materials, with a primary application in high-hardness steels and a secondary application in general steel. The extended reach and long neck make it well suited for deep-pocket contouring, mold and die cavities, and precision profiling passes where standard-length end mills cannot reach the workpiece. Single-end construction and a straight-cylindrical shank allow direct installation in standard collet chucks and hydraulic toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4.00 mm (0.1575 inch) ball nose diameter with 2.00 mm nose radius for fine contour work\u003c\/li\u003e\n\u003cli\u003eDUROREY PVD coating rated for hard material and hardened steel cutting\u003c\/li\u003e\n\u003cli\u003eExtended long-neck design: 16.80 mm neck length, 3.85 mm neck diameter for deep-reach access\u003c\/li\u003e\n\u003cli\u003e30-degree medium helix angle with helical flute geometry for smooth chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction; single-end construction\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of 0.005 mm for repeatable high-precision fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the OSG Series 8590 high-precision finishing long-neck carbide ball end mill line, designed for use in hard materials (Material Code H) and steel (Material Code P).

Ensure the machine spindle and toolholder are clean and free of runout before seating the straight-cylindrical shank. Confirm collet or chuck clamping torque follows the toolholder manufacturer specification for the shank diameter. Coolant-through is not supported on this tool; use external coolant or air blast as appropriate for the workpiece material and cutting parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1575 inches (4.00 mm)\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: DUROREY (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees (Medium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 60.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 3.85 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 16.80 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 20.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 2.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.005 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel\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: 8590\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 3056333\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744823017778,"sku":"3056333","price":107.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60638c19e579978d56152c9d3780ad4c_692c0997-759c-4c7b-994c-441864ca2aef.jpg?v=1788861002","url":"https:\/\/voomisupply.com\/products\/osg-3056333-ball-end-mill-0-1575-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
