The mill carries a 3.00 mm (0.1181 inch) cutting diameter with a 1.50 mm nose radius and a DUROREY PVD coating applied to the carbide substrate. The extended-reach long-neck geometry — featuring a 2.85 mm neck diameter and a 9.50 mm neck length — allows the tool to reach deep into cavities and pockets without pulling the shank into the cut. A 30-degree medium helix angle supports chip evacuation and surface finish in demanding materials classified under hard material (H) and steel (P) workpiece categories.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for finishing and light roughing passes in hardened steels and other hard-material applications where dimensional precision is critical. The single-end configuration, right-hand cutting direction, and right-hand helical flute geometry make it compatible with standard vertical and horizontal machining centers. The extended reach and small cutting diameter suit it for die and mold work, micro-pocket milling, and detailed contouring where clearance between the tool shank and workpiece walls is limited. It is sold individually and is intended for professional CNC machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDUROREY PVD coating for wear resistance in hard and steel workpiece materials\u003c\/li\u003e\n  \u003cli\u003eExtended long-neck geometry with 2.85 mm neck diameter and 9.50 mm neck length for deep-reach applications\u003c\/li\u003e\n  \u003cli\u003e2-flute helical configuration with 30-degree medium helix angle for effective chip evacuation\u003c\/li\u003e\n  \u003cli\u003e1.50 mm ball nose radius supports precise contouring and finishing passes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 6.00 mm shank fits standard collet and tool-holder systems\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of 0.005 mm for high-precision fitment requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-use tool for CNC machining centers accepting a 6.00 mm straight-cylindrical shank.

The straight-cylindrical shank requires a correctly sized collet or shrink-fit holder torqued to the machine manufacturer's specifications. Inspect the tool shank and holder bore for contamination before seating. Do not exceed manufacturer-recommended cutting parameters for the target workpiece hardness and coating designation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1181 inches (3.00 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\u003eOverall Length\u003c\/strong\u003e: 50.00 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\u003eLength of Cut\u003c\/strong\u003e: 2.40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 1.50 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: 9.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 11.90 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\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.005 mm\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\u003eWeight\u003c\/strong\u003e: 0.045 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 3056304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736000692530,"sku":"3056304","price":83.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60638c19e579978d56152c9d3780ad4c_1bfdc4b1-dc6b-43d6-a70d-3a326040e40e.jpg?v=1788775348","url":"https:\/\/voomisupply.com\/products\/osg-3056304-ball-end-mill-0-1181-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
