Seco has introduced the S-Ream Core, a new family of solid-carbide reamers intended for general-purpose hole finishing in P, M, K and N materials. The toolmaker places the range between its basic tooling and high-performance Nanojet solutions, targeting shops that need reliable, cost-efficient reaming rather than a premium option for every application.
According to Seco, the line is aimed at everyday production where dimensional accuracy matters but a high-performance reamer could represent an over-investment. The company says the range provides consistent hole quality, predictable tool life and a low cost per hole. A streamlined geometry, standard inspection and one universal coated grade are intended to reduce complexity while maintaining repeatable IT7 precision.
The reamers have straight flutes and a 30° lead. Seco lists 62 stocked diameters from Ø1.461 mm to Ø11.960 mm (0.057 in. to 0.470 in.), with additional sizes available through its MyDesign service.
The S-Ream Core also fits into a three-tier reamer portfolio alongside the Plus and Max ranges. Seco says this structure is meant to make tool selection clearer and more closely tied to the application. For buyers, the range is positioned as a middle option: more capable than a basic reamer but less specialized than the Nanojet line, with stock sizes covering a broad span of small-diameter work.
The single coated grade and standard inspection are presented as ways to simplify inventory and tool selection. With 62 stocked diameters, the range covers common small-hole sizes without special tooling; MyDesign remains available for sizes outside the standard list.
