Sanding bits are the most popular dremel bits of all. They are used to hone, polish, or enhance different materials like rock, metal, wood, clay, plastic, or even glass.
There are two types of sanding bits –

a) Drums

Drum bits resemble real-world drums with the skin off the top. They have a round cylinder shape.

First, you attach the drum to the end of the tool and slip up the sanding band onto the drum. Abrasive particles are glued on the band to sand down the substance. Drum bits help you sand large surfaces.
