A bench grinder is a fixed motor-driven tool that spins abrasive wheels for sharpening blades, shaping metal, removing rust, and cleaning up welds. It suits metalworkers, mechanics, and anyone who regularly sharpens chisels, drill bits, or lawn-mower blades. Look at wheel diameter (6-inch is common for home shops, 8-inch for heavier work), motor power measured in amps, and whether the speed is fixed or variable. Variable speed helps when you switch between grinding and buffing. Good tool rests and eye shields matter for safety and accuracy, and swapping the stock wheels for quality ones often improves results more than any single spec. Mount it to a solid bench to reduce vibration.
