HYGIENE
How can I prevent rust on my surgical drills?
To prevent this, we recommend paying attention to purity of materials. This means only reprocessing instruments that, according to the manufacturer, are suitable for this purpose.
For example, steel and carbide drill bits should not be processed together. Furthermore, care should be taken to avoid processing oxidized instruments to prevent surface rust.
How do I know how to prepare or store a drill bit?
Our product data sheets, which provide information on processing and storage, can be found in our shop under Downloads for the desired item.
