what kind of disk sander
Benchtop sanders are one-of-a-kind sanding machines that are built to last and offer more power, and control for larger sanding projects. They are commonly used by both do-it-yourselfers and professionals and are commonly found in home workshops. Benchtop sanders are less portable than handheld sanders but they offer more power and more versatility. The most versatile sanders offer a belt and a disc built into a single sander. Higher grade sanders are a good investment if you want to work with larger pieces of material or need to complete a lot of sanding work.
