Abrasive Discs: The grinder's effectiveness comes from its interchangeable abrasive discs, which are typically equipped with diamond or silicon carbide segments. These segments come in various grits, from coarse to fine, to achieve different levels of grinding and polishing.
Motor and Power: Concrete grinders are powered by electricity, gas, or propane. The motor drives the rotation of the abrasive discs, with more powerful machines capable of tackling larger, tougher jobs.
