The hammer drill is used not only for making holes in stone and concrete. It can be used as a chipper to remove tile coverings, dismantling works, and ditching channels for wiring. This equipment is designed for high loads and can work with extremely durable materials.
What is important at the time of purchase
When choosing a hammer drill, you should first pay attention to the power and strength of the impact. Performance depends on these two parameters. For example, if the power is 850 W, and the impact energy is 3.2 joules, then this equipment can work with soft concrete and brick. This model can be attributed to the light class, and its weight will be only 4 kg. The device will be able to make 20 mm holes if you need to install fasteners. You will be able to install plasterboard partitions and false ceilings.
Features of more powerful models
If we take as an example a rotary hammer with a power of 1,500 W, and the impact energy in it will be 20 joules, the device will weigh more than 10 kg, and it can be attributed to the professional class. The equipment will be able to handle hard materials like concrete and stone. The tool is designed for knocking out large holes for sockets and is used for installation work, chipping tiles and shredding channels.
Which rotary hammer to choose for domestic tasks
If you want to decide for yourself the question of which punch is best to buy for a home, you should also pay attention to the location of the engine. Horizontal models, for example, have the usual convenient shape for most home masters. If the device has a vertical layout of the engine and an L-shaped design, it will manifest itself more balanced and will be more compact. It is more convenient to work with such a puncher in difficult positions, for example, when drilling a floor or ceiling. This is due to the fact that less vibration is transmitted to the handle, the tool cools better and is able to withstand intense loads.
But the first of the options described is more suitable for solving problems at home. You can also pay attention to the type of food. The equipment may be battery or electric. These two models do a good job with concrete. The only difference is that the battery does not require a network connection and is designed for longer work.
Battery life is limited by battery power. But home masters quite often choose precisely such devices, because they are compact, cheaper, which means they are more suitable for those consumers who are used to using the tool only from time to time.
