The tool measures 0.0197 inches (0.50 mm) in cutting diameter with a 0.25 mm nose radius and features a 30-degree medium helix for stable chip evacuation during demanding cuts. A DUROREY PVD coating improves wear resistance and thermal performance at the cutting edge. The extended-reach, long-neck design provides clearance in deep-pocket and confined-feature applications where standard-length tools cannot reach. This mill is a single-end, right-hand cut and right-hand flute configuration suited for CNC machining centers running tight-tolerance finish passes.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use on hard materials and steels in precision machining environments, including die and mold work, aerospace components, and medical part manufacturing where small-diameter, high-accuracy cuts are required. The extended neck length of 8.10 mm and neck diameter of 0.48 mm allow access to features with restricted radial clearance. It is designed for use by machinists and tool-and-die professionals operating high-speed CNC equipment. The Series 8590 designation identifies it within OSG's line of high-hardness finishing tools.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.50 mm (0.0197 inches) cutting diameter with 0.25 mm ball nose radius for micro-feature finishing\u003c\/li\u003e\n\u003cli\u003eDUROREY PVD coating for improved wear resistance in hard and steel workpiece materials\u003c\/li\u003e\n\u003cli\u003eExtended-reach long-neck geometry with 8.10 mm reach length and 0.48 mm neck diameter\u003c\/li\u003e\n\u003cli\u003e30-degree medium helix angle with helical flutes for smooth chip flow\u003c\/li\u003e\n\u003cli\u003eSolid carbide substrate for rigidity and dimensional stability in high-hardness applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute, single-end configuration for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in hard materials (H) and steel (P) workpieces as specified by OSG material classification. Primary application is high-hardness steels. Consult OSG Series 8590 tooling documentation to confirm feeds, speeds, and machine compatibility before use.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool requires a CNC machining center with a collet or toolholder sized for a 4.00 mm straight-cylindrical shank; verify holder runout before use, as concentricity errors are amplified at this diameter. Power down the spindle and confirm zero-energy state before loading or changing the tool. The small neck diameter and extended reach make the tool susceptible to deflection — use the minimum stick-out necessary for the application. Follow the machine manufacturer and OSG recommendations for feeds and speeds when cutting hard materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0197 inches (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\u003eCoating\u003c\/strong\u003e: DUROREY (PVD)\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 (Medium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable Helix: No\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eLength of Cut\u003c\/strong\u003e: 0.40 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 8.10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 7.70 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\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\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel (P)\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\u003ePackage Dimensions\u003c\/strong\u003e: 2.6 x 0.6 x 0.35 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: 3056148\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728860184882,"sku":"3056148","price":89.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60638c19e579978d56152c9d3780ad4c_a45011ae-d077-44b1-80f9-0b9c0cf40cd2.jpg?v=1788697022","url":"https:\/\/voomisupply.com\/products\/osg-3056148-ball-end-mill-0-0197-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
