A 4-1/2 inch angle grinder is a corded handheld tool used with grinding and cutting wheels on metal and masonry. For metalworking the main choices are motor amps, no-load speed, weight and whether the switch is a slide or a paddle.

The six grinders below are all corded 4-1/2 inch models. Specs, weights and included parts come from each product’s listing page. We have not used these products ourselves. Read the manual for wheel limits, guards and handling before use.
