Seco has introduced the S-Ream Core, a new range of solid carbide reamers intended for reliable, cost-efficient reaming across P, M, K and N materials. The company positions the range between basic tooling and its high-performance Nanojet solutions. Seco says it is aimed at everyday production where dimensional accuracy is essential but premium tools may be an over-investment.
Seco describes the S-Ream Core as delivering 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. According to the company, these choices reduce unnecessary complexity while supporting repeatable IT7 precision.
The range has straight flutes and a 30-degree lead. It includes 62 stocked diameters from Ø1.461 mm to Ø11.960 mm (0.057 in. to 0.470 in.), with additional sizes available through Seco’s MyDesign service. The reamers sit within a three-tier portfolio—Core, Plus and Max—that Seco says is intended to make tool selection clearer and more application-focused.
The S-Ream Core therefore gives general-purpose users a defined option below the Nanojet line without moving to basic tooling. Its stated benefits are consistent with Seco’s positioning of the product for cost-sensitive, repeatable holemaking, while the announcement presents them as company claims rather than independently verified results.
