Abstract (en)
[origin: EP3235596A1] A screwdriver bit assembly includes a magnetic ring (2) mounted in a front end of a sleeve hole (14) of a sleeve (1). A retaining ring (3) is made of a material more rigid than the sleeve, is mounted in the sleeve hole (14), and is located behind the magnetic ring (2). A screwdriver bit (5) includes an insertion end (51), an extending section (53) behind the insertion end, a flange section (54) behind the extending section, and a clamping section (55) behind the flange section. The front end of the screwdriver bit extends through the sleeve hole (14) of the sleeve (1), the retaining ring (3), and the magnetic ring (2). The insertion end (51) extends beyond the sleeve and is located in front of a front end face (11) of the sleeve. The flange section (54) abuts the retaining ring (3). The clamping section (55) is held by a holding device (4) mounted on the sleeve (1), providing a holding force towards a longitudinal axis of the sleeve hole (14).
