How to choose the right chisel drill?

Choosing your chisel drill involves considering several criteria, particularly depending on the nature of the work you wish to carry out. So, how is this type of device used and what are the elements to take into account to make the right choice? We’ll tell you more throughout this article.

What are chisel drills used for?

These tools are used particularly in masonry works to drill concrete walls and other surfaces such as metal or wood. It can also be used to screw and unscrew, and its chiseling function is used in demolition work, such as replacing tiles or partially destroying a partition. To choose your chisel drill , you must first determine what use will be made of the chosen device.

The device can be available in several forms depending on whether it is intended for occasional, regular or sustained use. The difference between each device lies in particular in the speed (in revolutions per minute) and the power (in watts). Occasional use models deliver on average 3,000 impacts per minute and a power of 900 W, while the power of devices dedicated to intensive use can go up to 1,200 W.

What are the different models?

It is first necessary to distinguish between wireless models and wired devices. Choosing a chisel-spinner drill allows you to work completely independently from a power outlet and does not pose the problem of charging which is the responsibility of the batteries. These devices are also more powerful than cordless tools, and allow you to work more efficiently on relatively resistant materials, such as reinforced concrete.

For their part, wireless models are ideal for small sites without electricity. Their power is limited, as is their ability to work on particularly resistant supports. However, they offer better maneuverability.

We also distinguish between electromechanical hammer drills and electro-pneumatic models. The first provide percussion mechanically and have limited power, which is why they are often used by amateur DIYers. If you need ideas for carrying out small jobs at home with this tool, 

Electropneumatic models, for their part, are intended for larger-scale works, such as sustained use or demolition work carried out by professionals.

What characteristics should you take into account when choosing your chisel drill?

But how do you choose a chisel drill that suits your work and your needs? Here is a list of technical characteristics to consider to make the right choice:

  • Check the chisel strike frequency, expressed in number of strokes per minute.
  • The striking force is expressed in joules and it should be considered that a device with a striking force of 3 joules may be suitable for small sites. Professionals prefer models with a force greater than 5 joules.
  • Not all models are necessarily equipped with the three operating modes of rotation, perforation and chiseling. If you need all three, make sure your model can achieve them.
  • The rotation speed is the ability of the device to pierce your support. We consider that the average rotation speed of your device should be between 300 and 1,000 revolutions per minute.

There are different types of chucks and batteries which each have their specificities. As you will have understood, there are numerous criteria to take into account to obtain the right tool, so do not hesitate to seek the advice of a professional before making your decision.
