Rotary hammer is an easy to use and simple power tool that has been designed to ease the masonry tasks. It is also known with the name of pneumatic hammer and it has ability to drill through multiple materials like wood, concrete, plastics etc.
This is a heavy duty power tool that delivers impressive blow rate per minute so even if a user sets the speed at the lowest scale, the rotational speed at lowest scale is good enough to drill through the hard material without any trouble.
A rotary hammer has many different components so if you want to know how to use a rotary hammer, you must know the functions of these components. This information will guide you how to use a rotary hammer for excellent performance.
How To Use A Rotary Hammer
- Switch: Switch is the basic component of every corded rotary hammer. It allows the flow of electricity from the main power point to your rotary hammer.

On the contrary, large gear lowers the speed of rotary but the amount of torque produced by the rotary hammer is high. So if you know perfectly about the transmission of a rotary hammer then you can use it in a better way.
