WS-91 L G Surgical contra-angle with 1:2.7 speed increasing ratio, featuring mini LED+ light. The LED light is produced by generator built into the handpiece. The contra-angle with 45-degree head combines the advantages of straight and contra-angle handpieces.

Triple spray guarantees sufficient cooling of the instrument and the surgical site. Works with surgical burs, drills, cutters with FG (Friction Grip) shank 1.6 mm and 25 mm length. Push-button chucking system. Can be dismantled for cleaning.
