Seco has introduced S-Ream Core, a new range of solid-carbide reamers intended for reliable, cost-efficient reaming in P, M, K and N materials. The toolmaker positions the range between basic tooling and its high-performance Nanojet solutions.
According to Seco, S-Ream Core is aimed at everyday production where dimensional accuracy is required but premium tooling may represent an over-investment. The company says the range is designed to deliver consistent hole quality, predictable tool life and a low cost per hole.
The design uses a streamlined geometry, standard inspection and one universal coated grade. Seco says these choices reduce complexity while supporting repeatable IT7 precision. The reamers have straight flutes and a 30° lead.
Seco lists 62 stocked diameters from Ø1.461 mm to Ø11.960 mm (0.057 in. to 0.470 in.), with additional sizes available through its MyDesign service. The range forms part of a three-tier reamer portfolio—Core, Plus and Max—that the company says is intended to make tool selection clear and application-focused.
The three-tier structure places Core alongside Plus and Max, giving the lineup a clearly defined general-purpose tier below the company's Nanojet performance range. Seco describes Core as an entry point for production work that needs accuracy without a premium tooling investment, and the new range extends that position with specified diameters and a single coated grade.
