Handpads are versatile, general purpose tools that are used for a wide variety of manual applications such as grinding and polishing of glass, ceramics, stone, porcelain or composites. They are often used dry, but if using resin pads to obtain a more polished finish, they must be used wet, - plain water is usually perfectly ok. Diamond hand pads are available in galvanic or resin bond, in grits from 30 to 7000.
