With a 0.0591-inch (1.50 mm) mill diameter and a 0.75 mm nose radius, it produces accurate contoured surfaces and fine detail passes at small scales. The extended-reach neck geometry — 7.90 mm reach length and 1.45 mm neck diameter — allows access to deep pockets and complex features without tool deflection issues. The 25-degree medium helix promotes smooth chip evacuation and stable cutting action. A DUROREY PVD coating extends tool life in abrasive, high-hardness workpiece conditions. Licensed machinists and CNC toolroom technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThe OSG 3042002 is designed for finishing and roughing operations on hard materials, with steel as a secondary workpiece material. Its extended-reach configuration makes it well suited for deep-cavity mold work, die profiling, and tight-tolerance finishing passes where standard-length tooling cannot reach. The single-end, straight-cylindrical shank fits standard collet systems. The 50 mm overall length and 4.00 mm shank diameter make it compatible with common ER-style and precision collet chucks used in CNC machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard-material applications\u003c\/li\u003e\n\u003cli\u003eDUROREY PVD coating rated for high-hardness steels and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eExtended-reach neck (7.90 mm reach length, 1.45 mm neck diameter) for deep-pocket access\u003c\/li\u003e\n\u003cli\u003e0.75 mm nose radius with 0.005 mm mill diameter tolerance for high-precision finishing\u003c\/li\u003e\n\u003cli\u003e25-degree medium helix, right-hand cut, right-hand flute — helical flute geometry\u003c\/li\u003e\n\u003cli\u003e2-flute design optimized for fine finishing and detail work at small diameters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option within the OSG Series 8510 line.

Secure the straight-cylindrical shank in a clean, properly sized collet or toolholder to the manufacturer torque specification for the chuck system in use — do not exceed collet capacity. Verify runout with a dial indicator before cutting, as excessive runout at this diameter will shorten tool life and degrade surface finish. Follow shop-standard speeds and feeds for carbide tooling in hard materials; refer to OSG Series 8510 application data for recommended cutting parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0591 inches (1.50 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\u003eOverall Length\u003c\/strong\u003e: 50.00 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\u003eLength of Cut\u003c\/strong\u003e: 1.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.75 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 1.45 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 6.70 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 7.90 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 25 degrees (Medium)\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\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extended\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: h4\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 8510\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: 0.03 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: 3042002\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732760592690,"sku":"3042002","price":78.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32ca8f99de15acb42167cf7232b65bca_96fca3b2-ca5a-4d6f-b4d4-fad5296910da.jpg?v=1788746423","url":"https:\/\/voomisupply.com\/products\/osg-3042002-ball-end-mill-0-0591-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
