Seco develops new Duratomic grade for stable finishing of heat-resistant alloys

Seco has introduced the TS0501, a new Duratomic finishing grade engineered for the precise and reliable turning of high-hardness superalloys, including modern aerospace materials and established alloys such as Inconel 718. Developed for lights-out machining, the grade aims to increase tool life, process stability and surface quality in demanding aerospace and energy applications.

The TS0501 builds on Seco’s established turning portfolio with a focus on consistent finishing of heat-resistant superalloys. Its Duratomic coating and optimized cutting-edge design support high accuracy in environments where machining interruptions are costly and process variation must be minimized. According to Seco, the grade is engineered to maintain repeatable performance in unmanned operations, addressing the growing need for stable processes in automated production lines.

With improved wear resistance and thermal stability, the TS0501 is intended for applications where component quality and structural integrity are critical. The grade is offered in multiple geometries and chipbreakers to match specific finishing requirements across different setups. Full compatibility with existing toolholders enables manufacturers to adopt the new solution without reconfiguring their tooling systems, creating a straightforward transition for production facilities.

Optimized for reliability in lights-out machining

In sectors such as aerospace, where modern high-hardness alloys are becoming standard, machining reliability is a central requirement. Mikael Lindholm, Global Product Manager General ISO Turning, emphasizes this need: “When you’re machining modern, high-hardness aerospace components, there’s zero room for error. That’s exactly why we developed TS0501, to give manufacturers a tool they can trust to deliver flawless finishes, also on superalloys, shift after shift, even when no one’s watching the machine.”

The Seco TS0501 is designed to meet these expectations by providing predictable tool behavior under high thermal and mechanical loads, supporting longer unattended machining cycles and reduced downtime.
