Seco has introduced S-Ream Core, a new line of solid carbide reamers for general-purpose reaming in P, M, K and N materials. The toolmaker positions the range between basic tooling and its high-performance Nanojet solutions, targeting everyday production in which dimensional accuracy matters but a premium reamer may be more than the application requires.
The company says the range is designed to deliver consistent hole quality, predictable tool life and a low cost per hole. Its geometry has been streamlined, and the line uses standard inspection plus one universal coated grade. According to Seco, these choices reduce unnecessary complexity while supporting repeatable IT7 precision.
S-Ream Core tools have straight flutes and a 30-degree lead. Seco stocks 62 diameters from 1.461 mm to 11.960 mm, or 0.057 in. to 0.470 in.; additional sizes can be requested through the company's MyDesign service.
The reamers sit within a three-tier portfolio—Core, Plus and Max—that Seco says is intended to make tool selection clear and application-focused. In practice, the new line is presented as a cost-efficient option for standard production, not as a replacement for the premium Nanojet range. Its stated value rests on repeatable dimensional results, predictable tool life and a lower cost per hole rather than on the highest possible performance.
