The CELSIO heat-shrink system delivers high performance through induction heating, creating an almost homogeneous connection between the toolholder and the cutting tool. The Cool Flow variant features integrated coolant channels adjustable with M3 screws to direct coolant precisely to the cutting edge, while the Dual Contact version ensures optimal interface compatibility for machines with both conical and flat surfaces. Designed for high-speed machining (up to 50,000 rpm) and suitable for HSS/HM tools, it guarantees precision ≤ 0.003 mm (ISO 69882-8), excellent surface finish, and repeatability. Its reinforced shank combines slim design with rigidity, making it ideal for milling, drilling, and HSC applications. Balanced for G2.5 at 25,000 rpm, it is compatible with CELSIO SVL extensions, ensuring maximum flexibility and productivity.
