Getting Started for Repair Works For the first time, men, and sometimes even women, begin to pick up suitable tools for certain works. Initially, they borrow inventory from friends or neighbors, but subsequently understand that the main tool that may most often need it better have its own. One of these devices is a drill - a convenient and practical tool designed to drill holes in any material. Apply it in many works, namely in construction, household, grinding and other points when working with many materials.

Drill: Main characteristics

Drill power

This is one of the main parameters of this type of tool. From its characteristics depends on the operating time and service life. In this case, it is necessary to clearly decide for what purposes will be needed tool.
Usually, for home use, devices are selected with a small power, about 500 - 800 W. The tool of this force is ideal to drill the wall or mix the solution.
The average power also works well in the work on the assembly of furniture, for example, quickly fasten the self-tapping screw or a number of screws.
For more labor-intensive work, you need to choose the aggregates more powerful, already from 1000 W and higher.

Rotation frequency drill axis

The number and speed of revolutions directly depends on the power of the device. What it is higher, the faster and tidy the hole will turn out.
Speaking of grinding and polishing work, high speed here is no longer so necessary. In domestic use for screwing the screw or self-pressing, there will be a speed of 400 - 500 revolutions per minute.

Drill drilling diameter

This parameter must be specified in the Tool Passport. The minimum diameter is 0.6 cm, and the maximum - 25 cm.

Drill speed regulators

This is an extremely useful characteristic of a drill. When drilling it is better to use high speed, and to twist and unscrewing screws, so as not to harm yourself, the speed is suitable on slow revolutions, because at the time of screwing the self-pressing it has the property to scalin and lean. Therefore, the start button reacts to the slightest press. If you press it the maximum speed increases and vice versa, if you smooth, it decreases.

Fixators drill

With long work is a very convenient function. You can fix the speed and continue to work, not straining with your hand.

Additional drill parameters

Each manufacturer tries to invent additional features for more comfortable work and client attracting. This may concern, for example, backlighting the device, adjusting the cartridge, a set of spare batteries, a smooth start and other parameters for comfortable operation of a separate brand drill.

Principles of feeding drill

The time when the drill was manual and the speed of it directly depended on the endurance and the magnitude of the wizard, twisting the handle, has long passed. A shift manual tools came drill electric on the battery.
Nowadays, there are 7 types of devices of this type with a different functional set. From this considerable number of drills, you need to choose the one that is suitable for your needs.
To begin with, you need to decide for what purposes you need such a tool, and in what work you will use it. After all, by choosing and buying a professional drill for stealing money to twist the screws, take advantage of it only 2 - 3 times it does not make any sense. For such rare cases, it is enough to have a classic hand tool. And vice versa, a beginner master who will apply a drill in the professional sphere every day, while saving and buying a tool easier, risks it to regularly repair, stopping the workflow at the same time.
Construction tools are made to divide on professional and household. The first are intended for active and regular use, they are an order of magnitude harder and have a shockproof case. The price of such a tool doubly exceeds the cost of a simpler household appliance.
Home-sample drills are designed for use in everyday life. Often they are easier arranged, lighter, practical and convenient to use modern owners. Of course, their value is an order of magnitude lower, but starting to choose a drill, you should not forget that the miser pays twice. Even by choosing a household drill to buy, it should not save, it has to stop you a lot of years.

It is used to drive holes in simple materials, twisting the screws, hanging pictures and photographs, making stools and other household issues to the ambulance hand. The kit must have a sufficient number of drills.
It should be borne in mind that such a drill does not have special mobility, because it works only from the network, so when buying, pay attention to the length of the wire. Also during work, you need to do regular breaks by about 15 to 20 minutes, so as not to overheat the tool.
Work a classic drill can approximately 4 hours a day. Such a small amount of continuous work time is explained by the fact that household drills are equipped with low power and case material not one of the strongest.

Drill on the battery

Such a tool is extremely conveniently acquired for dachensors, where much has to work in the garden, on the plot, wherever the wire can not reach: on the arch for curly plants, for the roof construction, for the construction of benches arbor and other affairs on the plot.

What better to choose a battery drill? Specialists recommend paying special attention to the battery power, it depends on it, as far as the tool can work.

In addition, it should be borne in mind that, as a rule, the power of such a plan of drills is low, suitable for drilling not too hard materials.

Drill-screwdelt

This device is very convenient in home use. It will become an indispensable assistant when assembling furniture, twisting and unscrew the screws on the plinths, and other surfaces.
The screwdriver can work both from the battery and from the network. When choosing a battery drill, the screwdriver is not wondering what to buy, experts recommend to take with a speed controller that helps to set the mode at certain works. For example, when twisting the self-pressing is better at the initial stage, the speed is slower, so as not to harm the fingers, as it is tested to be tilted in different directions, and only later, when the screw will be screwed into the material by 20%, gradually increase the revolutions.
When choosing an electric drill, you need to pay attention to the length of the wire, but it can work longer in continuous mode.

Drill mixer

This is a classic drill, easily transforming into a building mixer.
Its feature is the presence of a special support handle, which is intended mainly for construction work, for example, kneading concrete, solutions, paints and other mixtures, no more than 10 liters.

Often, during construction or repair work, it is hard to get into hard-to-reach places, especially for the assembly of furniture.
For convenience, such situations invented a special angular drill. With its help you can get into the most hard-to-reach areas of work.
The tool itself has low power and has a narrow specialization. It is equipped with an angular gearbox, so the rotating shaft is perpendicular to the drill case.
Acquire such a drill is not always cost-effective. It is better to buy a regular device with a special angular nozzle that is put on a direct tool.

Hammer drill

One of the most solid, powerful and heavy drills of all listed is the drum tool. It refers to the construction devices of a professional sample.
Drill is used for processing mainly with solid materials. The principle of operation is that the axis of the tool is not only rotating, but also creates the impressions up - down, thereby performing the blows of a small amplitude. This approach is necessary for such works as a tile buckling, the holes in the concrete, brick. Such works can be compared with drilling wells.
What make a shock drill? Basically, the main factor here is power, the higher it, the topics and performance will be effective. And of course, you need to pay attention to the quality of the material and the protection of the tool.
