CERATIZIT showcased its OptiLine solid carbide end mills series at EASTEC 2025. OptiLine end mills are crafted from premium substrate with unparalleled tool geometry and superior Dragonskin coating. In addition, the solid carbide end mills are manufactured at CERATIZIT’s Sacramento, California facility and available in inch-assortment. “The OptiLine series represents one of our key differentiators as a cutting tool supplier," says Troy Wilt, managing director CERATIZIT USA. “We leverage our control of the entire carbide supply chain, from tungsten ore extraction to precision-crafted carbide end mills, to consistently deliver high quality, reliable tools to our customers.” Available in 4-, 5-, 6- and 7-flute options, OptiLine was developed for high performance machining for a wide range of materials, applications, and strategies. The 4-flute features variable helix and pitch and provides maximum stability for demanding operations. With constant helix and variable pitch, the 5-flute excels in a wide range of materials, making it a versatile workhorse of any shop. The OptiLine 7-flute end mill is perfect for HEM machining and light finishing. Its constant helix and variable pitch design ensure optimal performance across various metals. OptiLine’s 6-flute has an asymmetrical variable helix and variable index flute configuration that ensures enhanced stability during cutting operations and includes chip splitters designed for applications involving 2.5 x D cutting lengths. Exclusively introduced to the U.S. market in July 2024, the 6-flute was engineered specifically for titanium and super alloys. Much like the OptiLine 6-flute, the MaxiMill – 211-DC was developed for heat-resistant materials like titanium and other super alloys. At EASTEC, CERATIZIT featured the additively manufactured MaxiMill – 211-DC indexable insert milling system with advanced coolant supply. The milling system was created through in-house additive manufacturing with 3D-printed cooling channels. Additive processes allow the patented shoulder mill to funnel the optimum amount of coolant directly on the insert flanks. In turn, it provides process reliability when machining heat-resistant materials. The MaxiMill – 211-DC has 60% longer tool life compared to tools with standard cooling. Further, despite the complexity of the coolant holes inside the tool body, the MaxiMill – 211-DC is compatible with standard adapters with through-coolant supply without requiring any standard coolant on the chip breaker. "Our customers across all industries – aerospace, defense, and energy to name only a few – are machining difficult, heat-resistant materials every day,” Wilt says. “They require more from CERATIZIT, and we apply strategies like additive to deliver the high-performance results they need."
