Grinders are tools used to perform abrasive cutting or cleaning of materials, usually metal. They are handheld and fitted with a disc to suit the job at hand. Grinder manufacturers will offer a number of discs to suit different jobs, but as the grinders and discs will typically adhere to various design standards, it is not necessary to purchase discs from the same grinder manufacturers as the grinder itself, with available to locate necessary suppliers. Any grinder trader should also supply replacement discs. A large enough grinder trader will also be able to supply wholesale grinders, too.

Grinders can perform such tasks as cutting, cleaning, and polishing, depending on the disc they are fitted with. The disc is seated onto the grinder and fastened in place by holding down a locking mechanism to prevent the disc turning and then tightening the locking nut using a pin spanner. When in use, the grinder spins the disc at high speeds. Cutting discs and grinding discs are essentially the same disc, the main difference being that the grinding discs are much thicker. While a cutting disc is held perpendicular to the surface being worked, cutting a fine line with every rotation, a grinding disc is typically held at an angle and dragged, skimming the surface of the material rather than cutting directly into it. Abrasive discs, which consist of a series of abrasive flaps, can be used to polish a surface without removing too much material.

The market for wholesale grinders is a healthy one; metalworking is a tough job, and even the highest quality grinders have a limited lifespan when used constantly. There are many accessories, consumables (such as the discs themselves), and spare parts to consider, suppliers of which can be sourced at
