How to choose
- Read the chuck type and diameter from its body (e.g. 3204-160).
- Match jaws to the chuck series and number of jaws – the filters work the same way as in the lathe chucks category.
- Match the adapter plate to the spindle nose (type and taper size) and to the chuck diameter.

FAQ – frequently asked questions
What is the difference between hard and soft jaws?
Hard (hardened) jaws are for standard clamping; soft jaws can be turned on the lathe to the shape of a specific part, which improves concentricity in series production.
What is an adapter plate for?
It sits between the chuck and the spindle – it lets you mount a chuck with cylindrical mounting on a type A, C or D spindle nose.
