About this product
A spiral-cut aluminum flexible shaft coupler that joins a 6 mm shaft to a 10 mm shaft, with an outer diameter of 25 mm. The spiral cut tolerates slight misalignment between shafts while staying stiff in rotation, which suits precision CNC and 3D printer motion systems. It uses two sets of double set screws.

It connects a 6 mm motor shaft to a 10 mm shaft or rod in CNC machines, linear axes and 3D printer builds, while reducing the effect of minor shaft misalignment.
