Lathe chucks from TOS are an excellent choice for every machine shop, known for their reliability and quality. Equipped with 3 steel reversible and self-centering clamps, they ensure the concentricity of the workpiece with the chuck, offering accuracy and ease of use. The reversible clamps facilitate quick switching from internal to external clamping without requiring the complete removal of the jaws from the chuck. This series features a shoulder on the back (according to DIN6350), ensuring stability and easy mounting with the cooperating plates. The chuck-plate retention is done with 3 tightening screws on the front side.
