Bosch sanders come in many shapes and sizes. Which one you need depends on the type of job you want to use it for. For example, choose a Bosch belt sander or sheet sander if you want to finish large surfaces, such as a door. If you prefer to sand small corners or curved surfaces smooth, a Bosch delta sander or eccentric sander is a good choice. We also have Bosch sanders for the professional. These are the Bosch Blue sanders.
