Introduced as an economic alternative to the Super Precision chuck, these slightly slower rated chucks are an ideal replacement for fitting to an older lathe where high speed and super accuracy are not such an issue.
They also have a body made from high strength nodular iron with hardened and ground jaw strips and convenient, through the body mounting holes.
These chucks use the same wide range of ready to fit adaptor plates as Super Precision chucks.
