It features a 0.0197 inch (0.50 mm) mill diameter with a 0.25 mm nose radius and a 30-degree medium helix angle. The extended-reach long neck design provides a 7.60 mm reach length and a 0.48 mm neck diameter, giving machinists the clearance needed to access deep cavities and fine features without sacrificing rigidity. The tool is finished with a PVD-applied DUROREY coating for improved wear resistance in demanding cutting applications. Installed by CNC machinists and toolroom operators working in precision mold, die, and aerospace component production.\u003c\/p\u003e\u003cp\u003eThis end mill is part of the OSG Series 8590 and is built for use in hard material and steel machining applications where tight tolerances and fine surface finishes are required. The right-hand cutting and right-hand flute direction, combined with the helical flute geometry, support both roughing and finishing passes. The straight-cylindrical shank at 4.00 mm diameter ensures compatibility with standard collet systems. Its single-end, extended-length configuration makes it particularly well-suited for deep-cavity profiling and contouring work on CNC machining centers where access is limited.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0197 inch (0.50 mm) ball end diameter with 0.25 mm nose radius for fine-feature profiling\u003c\/li\u003e\n\u003cli\u003eDUROREY PVD coating rated for hard materials and high-hardness steels\u003c\/li\u003e\n\u003cli\u003eExtended long-neck design with 7.60 mm reach length and 0.48 mm neck diameter\u003c\/li\u003e\n\u003cli\u003e30-degree medium helix angle with helical right-hand flute geometry\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003eSupports both roughing and finishing material removal in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining applications involving hard materials and steel workpieces.

Ensure the machine spindle is fully stopped and the tool changer is disengaged before loading or removing the tool. Verify collet bore size matches the 4.00 mm shank diameter before clamping. Do not exceed the manufacturer-recommended runout tolerance of 0.003 mm for this diameter class, as excess runout will accelerate tool wear and compromise surface finish on hard workpieces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Inch)\u003c\/strong\u003e: 0.0197 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (mm)\u003c\/strong\u003e: 0.50 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\u003eNose Radius\u003c\/strong\u003e: 0.25 mm\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\u003eLength of Cut\u003c\/strong\u003e: 0.40 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 7.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.48 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 7.60 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 45.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.003 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: DUROREY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.6 inches L x 0.6 inches W x 0.35 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 3056147\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748659134770,"sku":"3056147","price":102.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60638c19e579978d56152c9d3780ad4c_5ad19ed4-4b10-4aa2-94c9-309359437d9b.jpg?v=1788896315","url":"https:\/\/voomisupply.com\/products\/osg-3056147-ball-end-mill-0-0197-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
