Sheets
Sheets can be AO cloth, AO paper and SiC paper. Flint Garnet and emery are also used for specific applications in wood work and electrical applications

The usual size for a sheet is 9” x 11”. Other common sizes are fractions of this such as 1” x 11” for file board use and 3 x 11” sheets for hand sanding pads.

Nonwoven sheets are referred to as handpads and are an essential item in any maintenance shop for general clean up. Their advantage over coated abrasive sheets being their conformability and  inherent resistance to water and metalworking fluids.
