Abstract

The dental device comprises an abrasive disk having a hub made of synthetic material and a spindle with a collet, the opening of the hub having an inner bead and the collet a rotation lock and an axial lock for receiving said bead in the hub opening, the greatest diameter of the spindle with its rotation lock being greater than the diameter of the hub opening with its bead. This construction allows, on one hand, an easier mounting of the abrasive disk on the spindle, and, on the other hand, a high torque transmission.
