Sanding drums are cylindrical tools used in woodworking and metalworking to smooth surfaces. They are typically made of a metal core wrapped in sandpaper, allowing for efficient sanding of various materials. Sanding drums come in different sizes and grits, making them suitable for both fine and coarse sanding tasks. These tools are often mounted on a drum sander or a router, enabling users to achieve a consistent finish on flat or curved surfaces. Sanding drums are popular among woodworkers and DIY enthusiasts for their ability to save time and effort while delivering high-quality results.
