Description
The WI-75 E/KM is W&H’sentry-level 20:1 implant contra-angle handpiece, designed to deliver reliable performance for routine implant placement and osteotomy at an accessible price point. Built around a durable stainless-steel body and precise gearing, the WI-75 E/KM supports predictable torque transmission and stable handling during implantology procedures.
Manufactured by W&H, this contra-angle features a push-button chuck with a hexagon chucking system and the Kirschner/Meyer internal bur cooling system to support efficient irrigation during implant site preparation.
Clinical indications
Implant placement
Osteotomy
Key features
20:1 reduction ratio for implantology applications

Important maintenance and usage note
The WI-75 E/KM cannot be dismantled for in-office servicing. For this reason, strict adherence to W&H-recommended cleaning, lubrication, and sterilization protocols is essential.
Improper maintenance can increase the risk of internal wear or seizure, potentially interrupting a procedure. In busy implant practices, it is strongly recommended to maintain multiple implant contra-angle handpieces to ensure procedures can be completed without disruption in the event of a handpiece failure.
