How to choose a drill?

Drill-tools necessary for each household and professional master. Without it, no picture does not hang or not to tie the shelf. With drills easily drill a hole in concrete or brick wall, in various wood and metal objects. It will also help in the assembly and repair of furniture and during other construction and repair work.

However, select the drill can be difficult, as manufacturers are now offering a huge variety of models. Therefore, many often wonder: how to buy a drill, and on what parameters to look at? Let's take a closer look at the types of drills and their features.

What classes are divided into drills?

There are three main classes of drills:

Home — they usually have a very simple packaging and are not designed for continuous and heavy loads. The housing is usually made of simple plastic, can be heated, so are not suitable for intensive work. At the same time they are the cheapest and quite cope with the simplest tasks that arise during the repair in the apartment, in the garage or in the country.
Class-Hobbi (semi) — these models are more powerful, can cope with the increased load and suitable for frequent and regular use. But still require periodic breaks. Recommended for use in small shops and workshops. They usually do well with a wide range of tasks. In value-is also at the center, more expensive home, but less professional.
Professional — the most expensive and powerful machines often have additional features that extend the capabilities of the drill and make it the most versatile use. Build quality is always excellent, high quality plastic and used high-quality metal elements. Characterized by the possibility of long-term continuous operation, this drill can work all day without failures and problems.

Types drill

It is a lot, let's look at the features of each type of:

Unstressed drill — these models have no impact function. They can be used to drill holes in wood, metal and plastic, for more solid they will not work, so how to make a hole in the concrete and brick this tool simply can not.
Drill — is small and light. As simple as possible to use, typically they are used in the assembly of furniture or for drilling small holes in the wooden surfaces. Some models may have a built-in flashlight to illuminate when the work is carried out in inaccessible and poorly lit areas.
Cordless drill — all the same as that of the previous one, but these models are powered by a rechargeable battery. Thanks to this tool is more mobile, it can work even where there is no access to a power outlet.
Impact Drill — has 2 modes of operation: drilling and hammer drilling. This increases capacity and allows you to drill hard materials: concrete, brick, concrete block, etc. A great companion for home repairs.
Angle Drill — this is a highly specialized tool that is designed to work in tight spaces. They have a special hull form, which allows them to easily cope with the assembly of complex, angular designs. In everyday life is not usually used as a professional, specific tools for specific tasks.
Drill-mixer — This type includes powerful unstressed heavy drills used for mixing various mortars. Also, they can drill large diameter holes or working bits for wood or metal. Typically, such drills have no cartridge screwed directly into the beater shaft. Used on construction sites, where it is often necessary to disturb large amounts of adhesives, fillers and other compounds.

Main features

At the drills have some basic technical parameters that must be considered before you buy a tool.

Power

The main characteristics that we must look, choosing a drill. What it will be higher, the more complex tasks can handle a tool, but also they will be and harder. It is important to find a balance.

Generally, for home use may best take a power drill 750-900 watts. The weight of such models can range from 2 kg to 6.5 kg.
Have a professional capacity starts at 900 W and can be up to 1500 W and above. But there is a price, as they are quite heavy and long to keep such a machine in the hands of hard, especially without training.
Low-power drill 300-500 W can cope with only a small amount of work, time of continuous operation is also very limited. These models are suitable except for simplest tasks, because the handle can only be with drilling holes in soft and not very thick materials.

However, one is not always enough power to get a convenient and practical tool, it is necessary to look at its functionality as a whole.

Type of gear

This parameter determines the reliability and efficiency of the drill work. The gearbox can be 1-speed and 2-speed.

One speed — these models are well suited for home repair, can be used as a screwdriver. With their help, if necessary, can knead solution or several small holes drilled in the wall. These models are relatively inexpensive.
Two speed — it is expensive multifunctional drill that can absolutely free to carry heavy loads. In addition to the powerful gear they also have reinforced chassis and powerful engine. With their help, you can quickly knead any solutions, drilling brick and thick metal working bits for wood and much more.

It is also important that the material from which made the gear housing. It must be durable good heat dissipation. For home use is better to choose a drill with a metal gear, the plastic can also be considered, but it should be as strong.

Torque

It is also a very important parameter for the drill, it determines the ability of the tool to perform complex tasks without overloading.

The torque-is the force that creates the drill to rotate the drill bit or bits, it is measured in Nm (Newton-meters). The figure is higher, the more dense material can run this tool. Please note that additional transmission links help to increase the torque.

Adjust speed

The availability of this function allows you to increase the efficiency and accuracy in the process of screwing elements. The adjustment of drilling is carried out by pressing the trigger, or by means of additional electronics units which stabilize the number of revolutions, and this value is maintained constantly even under heavy load.

Cartridge

The choice of cartridge is also very important, as it determines the ease and reliability of drill bits or fixation. The cartridges come in 2 types:

Key — the right to call them rack and girth. This is a popular variant of the clamping mechanism. The main plus attachment-the reliability of fastening, even at high power drill will be held firmly. To fix the drill requires a special key.
Quick-action — it is more convenient and practical option as to fix it, you can drill without tools, it greatly speeds up and simplifies the process. Divided into single-seat and double box. Single-seat cartridges difficult to disassemble and fixing them is not the most reliable. Double box consist of two elements, which makes them easier to use. For clamping the drill, it is necessary to hold the lower part of the cartridge with one hand, and the other to twist or clamping the sleeve.

Shot Mode

Instrument having a similar function is more versatile. But do not forget that all the percussion drill-this is not the punch. For them, hammer drilling-not the main feature. With frequent and prolonged with impact drilling gear teeth worn down, which leads to the exit mechanism of action. So remember that drill with fiction hit, it's all the same household drill, which is designed for drilling holes and holes breakdown in concrete and masonry-a handy additional option that extends the possibilities of the instrument.

What is the best drill: wired or battery

The clear answer to this question is difficult, as they both have their own characteristics and advantages.

Wired drill, working from a fixed electrical network 220, reliability and stability-it is a big plus. However, if it is necessary to drill in the area where the wiring is still there, it is better to fit a drill on the battery. Then you do not have to look for a source of energy or to mess with extensions. Choosing a wireless model, it is better to give preference to options with a replaceable battery. It is practical and convenient, do not have to be interrupted to recharge, while one battery is working, and the second will be recharged.

If you need a drill for occasional use and solve minor household tasks, it is fine wire, it is cheaper. For active work in different environments and wide range of applications, it is best to choose a battery with good power indicators. Such a tool would be more effective and longer work.

Remember that the choice of drills-the task responsible. To make the right choice, it is necessary to take into account all the nuances intended use of the instrument and the future burden.
