Cutting concrete is never a simple task, however when using the right angle grinder, the job can be accomplished relatively easily.
An angle grinder is sometimes known as a disc grinder or side grinder and is a hand held power tool which is used for polishing and abrasive cutting.
These versatile tools are ideal for all kinds of cutting tasks including cutting tile and paving thanks to their ability to handle a range of accessories and wheels, with the possibility of installing them in several configurations for the greatest flexibility of use.
However, when planning on cutting concrete, it is important to choose one with a more powerful motor as it will be more capable of handling such a heavy duty task.
One which draws somewhere between 5 and 9 amps should be adequate to complete concrete cutting with ease.
The best angle grinder for concrete is one that features a dry cut diamond blade as this is the best choice for performing difficult cuts through concrete materials.
