Seco has expanded its reaming portfolio with S-Ream Core, a new family of solid-carbide reamers intended for general-purpose production in P, M, K and N materials. The company positions the range between basic tooling and its high-performance Nanojet reamers, aiming to balance consistent hole quality and predictable tool life with a low cost per hole.
According to Seco, the line is aimed at everyday manufacturing that requires dimensional accuracy but does not justify a premium reaming solution. A streamlined geometry, standard inspection and a single universal coated grade are intended to reduce complexity while supporting repeatable IT7 precision. These are product-positioning claims; the announcement does not provide independent test results or customer case data.
Specifications and portfolio fit
S-Ream Core tools have straight flutes and a 30° lead. Seco lists 62 stocked diameters from Ø1.461 mm to Ø11.960 mm (0.057–0.470 in), with additional sizes available through its MyDesign service.
The range sits in a three-tier reamer portfolio alongside Core, Plus and Max, which Seco says is meant to make tool selection clearer and more application-focused. For buyers, the launch adds a middle option for routine reaming work, while the availability of custom sizes may help cover diameters outside the standard stock list.
