Orbital sanders can also be used to buff metal. Because these are small sanders, they will cover less ground than a larger sander, but have the potential, when combined with an appropriate sanding sheet to give a fine finish for detailed work.

• The key consideration when choosing an orbital sander is the size & shape of pad most suited to the work. This size of orbital sander is for medium sanding. Orbital sanders with a round backing pad can also be used to polish as well as buff wood & metal.

• Some orbital sanders have a variable speed function ie. allowing for a slow start on the trigger. Additionally some have more than one speed setting. Most sanders are mains operated although there are some cordless now coming to the market. **Battery words**
