Part of the OSG Series 9110 Exocarbmax line, it is engineered specifically for materials exceeding 55 Rc hardness. The mill measures 3.00 mm (0.1181 inches) in diameter with a 4.50 mm length of cut and a 50 mm overall length. It features a 6.00 mm straight-cylindrical shank with an h6 tolerance, a 30-degree right-hand helical flute geometry, and a WXS TiAlN PVD coating. The ultra-fine micrograin carbide substrate and two-flute design handle both roughing and finishing operations in a single tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for precision machining in tool and die, mold making, aerospace component work, and general metalworking where tight tolerances and hard-material capability are required. Its stub-length classification keeps the tool rigid during aggressive passes in hardened steel. Secondary workpiece material compatibility extends to stainless steel, superalloys, and titanium, making it versatile across a range of difficult-to-machine materials. It is a single-end tool with a 1.50 mm nose radius and right-hand cutting direction.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3.00 mm (0.1181 inches) ball end diameter with 1.50 mm nose radius for contoured surface work\u003c\/li\u003e\n\u003cli\u003eWXS TiAlN PVD coating rated for hardened steels over 55 Rc\u003c\/li\u003e\n\u003cli\u003eUltra-fine micrograin solid carbide substrate for edge strength and wear resistance\u003c\/li\u003e\n\u003cli\u003e30-degree medium helix, two-flute design supports both roughing and finishing\u003c\/li\u003e\n\u003cli\u003e6.00 mm straight-cylindrical shank with h6 tolerance for accurate tool holding\u003c\/li\u003e\n\u003cli\u003eNo coolant-through, no chipbreaker, no variable helix — simplified geometry for predictable performance in hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for machining steel, cast iron, and hard materials (ISO material codes P, K, H) as primary workpiece materials, with secondary compatibility for stainless steel, superalloys, and titanium (ISO codes M, S).

Confirm tool holder bore and collet size are compatible with the 6.00 mm shank diameter before mounting. Verify spindle runout is within acceptable tolerance for small-diameter end mills to avoid premature tool breakage. Always follow machine tool manufacturer guidelines and relevant shop safety procedures when machining hardened or difficult materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eLength of Cut\u003c\/strong\u003e: 4.50 mm\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 Tolerance\u003c\/strong\u003e: h6\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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Ultra Fine Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: WXS TiAlN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 9110\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 91100311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752597422386,"sku":"91100311","price":197.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df8dbab5d5b86f507cba28b735df88b3.jpg?v=1788929288","url":"https:\/\/voomisupply.com\/products\/osg-91100311-ball-end-mill-0-1181-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
