It carries a 3.00 mm (0.1181 inch) mill diameter with a 1.50 mm nose radius and features an extended long-neck geometry, providing 13.90 mm of reach length with a reduced 2.85 mm neck diameter. The DUROREY PVD coating is applied to extend tool life in demanding hard-material applications. The 30-degree medium helix angle promotes chip evacuation while maintaining edge stability during fine finishing passes. Licensed machinists and CNC toolroom technicians are the primary installers and operators of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is built for hard material and steel applications requiring long-reach access into deep pockets, slots, or contoured surfaces where standard-length tools cannot reach. The extended neck design allows the 3.00 mm cutting diameter to reach into confined features while the 6.00 mm straight-cylindrical shank seats securely in standard collet chucks or end mill holders. The 50.00 mm overall length supports use on vertical and horizontal machining centers in both roughing and finishing operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.00 mm (0.1181 inch) ball end diameter with 1.50 mm nose radius for precise contour finishing\u003c\/li\u003e\n\u003cli\u003eDUROREY PVD coating optimized for high-hardness steels and hard materials\u003c\/li\u003e\n\u003cli\u003eExtended long-neck geometry with 13.90 mm reach length and 2.85 mm neck diameter\u003c\/li\u003e\n\u003cli\u003e2-flute right-hand helical flute design with 30-degree medium helix angle\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003eSingle-end design with straight-cylindrical 6.00 mm shank for standard collet compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard collet chucks or end mill holders accepting a 6.00 mm straight-cylindrical shank.

Confirm collet chuck runout is within tolerance before use, as carbide tools at small diameters are sensitive to radial runout. Power down and lock out the spindle before loading or removing the tool from the holder. Do not exceed the tool manufacturer's recommended cutting parameters for speed, feed, and depth of cut when machining hard or hardened materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3.00 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 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\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\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\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\u003eOverall Length\u003c\/strong\u003e: 50.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.40 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 2.85 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 11.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 13.90 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: h4\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 (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\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 Weight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.65 inches L x 0.6 inches W x 0.4 inches H\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: 3056305\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748647043378,"sku":"3056305","price":83.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60638c19e579978d56152c9d3780ad4c_f045f12f-3781-4913-9ca5-a8bc20cbc883.jpg?v=1788896146","url":"https:\/\/voomisupply.com\/products\/osg-3056305-ball-end-mill-0-1181-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
