Multi-sanders are flexible tools that are used to sand small areas and carry out detailed work. These sanders come in a range of designs and configurations and typically support different types of sanding sheets. This allows these sanders to be used for sanding, polishing and buffing wood and metal. They are often used by decorators, cabinet makers and other woodworking trades.

• Most sanders are mains operated although there are some cordless now coming to the market. Choosing your power source: The first choice is between a mains (110v or 240v) or a cordless tool. 240v tools are used with normal mains power whilst 110v tools are used on construction sites for safety reasons.
• With regards to cordless (battery powered) tools there are a variety of chemical types; Li-ion is the latest technology, prior to that it was Ni-MH and Ni-Cad was the original. The higher the Ah (Ampere hours) the longer the interval between charges; the fewer times you recharge a battery the longer it will last. Some cordless tools can also come without batteries - sometimes referred to as naked, bare units or body only. These tools are supplied without a battery or charger and more often than not without any accessories; as a result they are significantly cheaper in price.
