The next-generation Duratomic insert technology from Alcester-based Seco Tools (UK) Ltd (www.secotools.com/uk) has been put to the test up and down the country by precision component manufacturers and cutting-tool distributors and dealers looking for the most productive turning solutions.

One leading tooling and cutting-tool distributor in the South West recently put the Duratomic TP2501 grade through its paces, as Seco’s area business manager, Tony Butterworth explains.

“The TP2501 grade was used to machine a large, precipitated stainless-steel component. It was benchmarked against a competitor’s insert under the same test conditions and using the same cutting data — a speed of 120m/min, a feed rate of 0.32mm/rev and a depth of cut of 3mm.”

To machine the part using the competitor’s product required the use of three insert edges; with the new TP2501 grade, the part was machined complete using just one edge — a significant improvement in insert edge productivity and one that represents a considerable reduction in the cost per part.

“TP2501 is an incredibly tough and wear-resistant grade that improves productivity, performance and process reliability. It has been designed to machine a wide range of steels where unstable machining conditions exist, and where heavy-duty interrupted cuts are the norm.”
