New range of circular saw blades STARK has introduced the Olympic range, dedicated to tube cutting applications. The line includes circular saw blades suitable for differing applications. stainless steel inox and also non-ferrous material. The most common applications are fly-cut machines with single or double cutting heads, orbital cutting machines (including stainless steel cutting), and automatic cut-off machines suitable for tube cutting.

The Olympic range also includes a line of TCT circular saw blades suitable for orbital cutting machines. For cutting tubes with large dimensions using orbital cutting heads equipped with two to four blades, Stark developed a new PVD-coated, re- sharpenable blade with special tooth shape, aimed at reducing effort during cutting and achieving a longer tool life. According to the section and the material to be cut, the company can supply different toothing geometries specially developed to obtain the highest cutting performance. The Stark Group has a network of distributors, and four branches – Stark GmbH in Germany, Stark do Brasil Ltda in Brazil, Frund-Stark SA in Argentina, and Stark Tools (Suzhou) Co Ltd in China.

For its Olympic HSS circular saw blades, Stark wanted to join the best surface coating (PVD technology) developed in its well- equipped laboratory with the HSS blade produced with the lowest tolerances. The new coating is suitable for cutting high tensile strength material and abrasive materials, and perfect for dry cutting. Thinner cutting edge and very narrow blade manufacturing tolerances grant very low cutting efforts, higher cutting quality and longer blade life. All of the blades are individually checked and their measured tolerances included in a quality report. This type of HSS circular saw blade is suitable for materials including carbon steel, alloyed steel with high tensile strength,

Olympic TCT throw away circular saw blades are designed to meet requirements for steel’s higher tensile strength values, greater tube thickness and faster production line speed. When the hardness and thickness of the material to be cut increase, it is possible to reduce machine down times using Olympic blades instead of traditional blades; according to Stark, the circular saw lasts longer while granting a faster cutting operation. The blades have a PVD surface coating for this specific application. Every blade is inspected and marked with a batch number to guarantee cutting performance consistency.
