<p>The invention is based on a power tool braking device, in particular a handheld power tool braking device, of a portable power tool, comprising at least one braking unit (14a; 14b; 14c), which is intended for braking a movement of a working tool at least in one operating mode. It is proposed that the braking unit (14a; 14b; 14c) has at least one rolling-contact element (18a, 20a, 22a; 18b, 20b, 22b; 18c, 20c, 22c), which is intended for activating at least one braking mode of the braking unit (14a; 14b; 14c).</p> |
