Proxxon Collet Set for PD250/E

For accurate use on round components. One of each ER20 collet is included: 2.0, 3.0, 4.0, 5.0, 6.0, 8.0, and 10. Concentric accuracy is just about as good as you can get and much better than a chuck. The included ER20 collet attachment is mounted in the place of the headstock chuck.
