Seco Tools has introduced Seco® S-Ream Core, a new range of solid carbide reamers for general-purpose reaming in P, M, K and N materials. Offered in 62 stocked diameters from Ø 1.461 mm to Ø 11.960 mm, the range sits between basic tools and Seco’s high-performance Nanojet™ solutions.
According to the company, S-Ream Core is designed for everyday production where dimensional accuracy matters but a premium reaming solution may represent more investment than the application requires. The range targets consistent hole quality, predictable tool life and a low cost per hole.
Simplified geometry, one coated grade
S-Ream Core uses a simplified geometry, standard control and a single universal coated grade. Seco says this approach removes unnecessary complexity while delivering repeatable IT7 accuracy.
The reamers feature straight flutes and a 30° lead angle. The 62 stocked diameters correspond to 0.057 in to 0.470 in; additional sizes are available through the company’s MyDesign service.
A three-level reamer portfolio
S-Ream Core is part of Seco’s three-level reamer portfolio of Core, Plus and Max. The company says this structure makes tool selection clearer and more application-focused.
Jean-Bernard Hantin, Seco’s product manager for reaming, said customers need reliable reaming performance without unnecessary cost or complexity, adding that S-Ream Core focuses on the essentials of precision, consistency and easy tool selection.
