You should check the cutting blade and pilot drill of your tank cutter regularly to see if they need replacing. After extended use, you will need to purchase replacement parts to ensure that your tool continues to work effectively.
Cleaning
After use, you should clean the cutting blade of your tank cutter to remove any unwanted material. To do this, apply a cleaning solvent like WD-40 and carefully wipe with a cloth.
Storage
You should wrap your tank cutter in a rag or cloth to protect its cutting blade, before storing it in a cool, dry place like a toolbox. This will help to prevent corrosion or rust from damaging the tool.
