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 company positions the range between basic tooling and its high-performance Nanojet solutions, targeting everyday production where dimensional accuracy matters but a premium tool may be an over-investment.
According to Seco, the range combines a streamlined geometry, standard inspection and one universal coated grade. The company says this approach removes unnecessary complexity while supporting repeatable IT7 precision, consistent hole quality, predictable tool life and a low cost per hole.
Stocked sizes and portfolio position
S-Ream Core features straight flutes and a 30° lead. It is available in 62 stocked diameters from Ø1.461 mm to Ø11.960 mm (0.057 in. to 0.470 in.), with additional sizes offered through the MyDesign service.
The range sits within a three-tier reamer portfolio—Core, Plus and Max—that Seco says is intended to make tool selection clear and application-focused.
The introduction gives manufacturers a middle option for production reaming, balancing cost and precision without moving directly to premium tooling. Seco’s claims focus on repeatability and cost per hole; the range is presented as a standard, application-focused solution rather than a high-performance upgrade.
