What affects an angle grinder's wattage
An angle grinder is rated around 1,200 W, but the real figure shifts with a few things:
- Model and rating: An angle grinder ranges from about 700 W on efficient units to 2,500 W on larger or older ones — a spread of ~1,800 W.
- Usage: the real draw depends on the material and load you put it under.
- Run time: because an angle grinder only runs in short bursts (a few minutes at a time), hours of use matter as much as raw wattage on your bill.
