Seco has introduced S-Ream Core, a new range of solid carbide reamers aimed at reliable, cost-efficient reaming in P, M, K and N materials. The company positions the range between basic tooling and its high-performance Nanojet solutions, with the goal of consistent hole quality, predictable tool life and a low cost per hole.
According to Seco, the tool is intended for everyday production where dimensional accuracy matters but premium reaming solutions may be more than the application requires. A streamlined geometry, standard inspection and a single universal coated grade are intended to reduce complexity while maintaining repeatable IT7 precision. The range thus targets users who need dependable accuracy without moving to a premium tooling tier.
The range uses straight flutes and a 30° lead. It includes 62 stocked diameters from Ø1.461 mm to Ø11.960 mm (0.057 in. to 0.470 in.), and additional sizes are available through Seco’s MyDesign service. The company groups S-Ream Core within a three-tier reamer portfolio—Core, Plus and Max—to make tool selection clearer and more application-focused.
Seco’s description presents S-Ream Core as a general-purpose option rather than a replacement for its highest-performance reamers. The stated benefits—repeatable accuracy, predictable life and lower cost per hole—are tied to the range’s design and grade. The announcement does not provide independent test results, application case studies or a release date.
