Attention! Sale of discounted goods. The reason for the markdown: in this batch, the diameter of the mounting hole of the cartridge has a positive tolerance instead of the manufacturer's declared -0.02 mm. Accordingly, an "interference" fit on the motor shaft is not always ensured if the shaft also does not have a positive diameter tolerance.
It is recommended to use a chuck in cases where the spindle shaft is made specifically for this instance of the chuck and the fit can be adjusted.

Collet for CNC machines.
For installation on a shaft with a diameter of 8 mm, tolerance -0.02 mm.
