There are two important factors to consider when buying sander parts. One is what you are using the sander for, and the other is why your sander needs a new part. These two considerations can help you find the parts you need. If you find yourself continually replacing the same parts, however, perhaps you need to use a different type of sander for your projects.
The first thing to consider when buying sander parts is cost. Cost is a major influence on deciding whether to buy used parts or new parts. Used parts are always less expensive than new parts, but that doesn't always mean you'll save money. For example, if a used part saves you $20 US Dollars on a $60 USD purchase but lasts only one month, you probably will end up spending a lot more than the $20 USD that you originally saved.
Used electric sander parts should be inspected carefully for wear and tear. Make sure that all moving parts move smoothly, and always check for any cracks in the parts before you buy them. Used sander parts can be a great bargain as long as there is little to no damage present. Little scuffs on the part or discoloration shouldn't be a problem for the functioning of the part, but how much aesthetics matters is up to you.
Some parts, such as sandpaper or sanding belts, need to be replaced a lot more often than other parts. The sandpaper and sanding belt wears down when it's used, because of the very nature of its function. The only thing that really needs to be considered when buying sandpaper or sending belts is what kind of sanding you are doing. It is a good idea to keep plenty of sandpaper and different types of belts on hand with different levels of abrasiveness so that you are prepared for any project that comes your way.
Another example of commonly used sander parts are sanding pads. Sanding pads are used to secure the sandpaper to your sander. The type of pad you buy should be determined by the type of sander. If you're unsure, it's a good idea to ask the salespeople what they think is appropriate for your specific sander.
Make sure that your part is compatible with the model of your sander. There are many types, models and brands of sanders. A part might look the same and function the same, but tiny mechanical differences in models can prevent a different model's part or different brand's part from functioning with your sander. Check with a guide or salesperson before finalizing your purchase to ensure that the part you buy is compatible with your sander.
