There are a lot of cases when you have to demolish a wall or something else at a construction site. While you can do this using a hammer and a chisel, that can be quite time-consuming. Hence, it is recommended to use a demolition hammer in such cases because of the following things offered by them:Motor Power: As these demolition hammers are powered by an electric motor, checking the power rating is highly important. Just like any other tool, this power rating is given as 10 amps or 20 amps, where a higher power rating results in higher performance.Speed: Demolition hammers also come with a speed rating that is given in BPM or blows per minute. While some options are rated at 1900 BPM, more powerful ones will have a speed rating of 2600 BPM.Chisel Size: There is a chisel on one side of any given demolition hammer that is responsible for the demolition process. Some of these have a 1 ¼ inch chisel, while others might have a 1 ¾ inch chisel depending on the model that you get. Out of these two, the larger chisel size offers better performance to the user.Specifications:Two modes setting: Rotary drilling & hammer only with idle position.
