Diamond is the hardest substance on earth and is used to cut and polish other hard substances. In the past, all diamonds were mined, but now industrial diamond grit is man-made to ensure uniform shape and size of the particles. The process uses extreme heat and pressure to emulate the natural conditions that cause diamond crystals to form. Grit particles are bonded together onto an assortment of backings to be used for polishing and smoothing of all types of stone.

Polishing and Grinding Machines

Machines for use with diamond polishing tools include electric and pneumatic hand-held polishing machines. Diamonds create extreme heat when rubbed against stone, and most diamond tools have attachments for water to be distributed over the stone while grinding. A bevelling edge is a tool used in conjunction with a hand-held polishing tool to help create a consistent angle when bevelling the edges of stone countertops or tiles. A floor polisher is a larger walk-behind machine with the same basic properties.

Diamond Polishing Pads and Discs

Diamond polishing pads are round, usually three to six inches in diameter, and are made to fit hand-held angle grinders or polishing machines. They come in varying grit coarseness to suit all types of stone. Diamond polishing discs are similar to the pads and are for use on floor polishing machines. Most diamond pads and discs are made for use with water but some are specially designed to work without water for cooling.

Diamond Cup Wheels

Diamond cup wheels have hollow convex metal cores with metal diamond-impregnated segments brazed or laser welded onto them.They are used with hand-held machines and are coarser and more durable than the pads for grinding down rough or raised areas of stone. They are made to be used with or without water for cooling.

Diamond Hand Pads

Rectangular diamond hand pads are made from industrial diamond grit bonded with resin or electroplated onto a pad backed by a foam grip, similar to a chalkboard eraser in size and shape. The pads come in varying sizes of grit from coarse to fine. They come in choices to suit all types of stone, including granite, marble and travertine to name a few. The pads are used for hand polishing. Some pads must be used with water while others can be used dry.
