Likely, in each modern dwelling there is electric tool. It can simplify considerably many works and also will allow to make life more comfortable. The hammer drill is one of the most widespread electric tools.
1. Distinctive feature of such drill is the principle of its work. Besides that rotational motions are carried out, the mechanism also carries out forward blows. Their force is 2 J. By means of the hammer drill it is possible to make opening even in very solid material. To benefit from it the tool at most, it is necessary to approach its choice thoroughly.
2. For a start it is necessary to pay attention to power supply of drill. It can work not only from network, but also from accumulators. The network drill has the small weight as in it there are no accumulators. However by means of the tool which works on the storage battery it is possible to make opening even in those places where sockets are not provided. At the drill working from network, big power in comparison with battery room. For this reason it is much simpler to work with it. Consider if the accumulator fails, you should buy new for decent money.
3. After you have chosen energy source, can pay attention to power. The tool is more powerful, the it will be simpler to work with it. It will be more expensive. It is recommended to get powerful drill. For many years you will enjoy ease of its operation. The drill which has the power of 700-900 W perfectly is suitable for domestic needs. It is worth to remember about ratio "more than the power – simpler operation".
4. At the hammer drill there are a lot of various characteristics. The main of them are the power rating, rotational speed idling and also diameter of the formed openings for various materials in the mode with blow. On sale you can meet tools which have the rotation velocity adjuster. It is possible to regulate by force of pressing the start-up button. In some types there is special disk regulator. At the moment there are models with the processor which chooses and supports optimum rotational speed. Speed depends on chosen like material and from diameter of drill. The good drill surely has reverse. This mechanism allows to rotate drill in both parties. It is necessary to take out drill which has got stuck in the processed material.
