The range of power tools on the market is large, but not everyone knows how to make the right choice. Therefore, it is worth starting to understand the classification and purpose of products. Each requires its own equipment and tools. Understanding this issue is not so difficult. And today we will consider the types of power tools, the purpose, application and features.
The main differences
There are several different classifications. The very first - by appointment.
- To create holes, various recesses and threading there are: drills, screwdrivers, punchers, jack hammers and thread cutters. There are other options, but this list is the most common and often found on the market.
- For wood finishing. This is planing, sawing, as well as milling. This includes a jigsaw, a plane, a variety of saws, milling cutters and a grinder. These are the main types of power tools that a person needs. If necessary, you can buy something else.
- To make the part perfect, it is polished and polished. This can not always be done manually. So, there are files, grinders and chippers. With them, the part becomes flawless in a short period of time.
- There are also types of power tools, without which it is difficult to imagine any work. These are hair dryers, a vacuum cleaner, a soldering iron and other related equipment. They are classified as household appliances. Such are available in every house or apartment.
There are various types of hand held power tools. These are those that can be carried and applied anywhere. They can be used depending on the need, which is very convenient. But there are those with the help of which you can do some work, but transferring constantly does not work.
It is clear that portable ones are capable of performing a wide variety of functions, but the advantage of a stationary one is the performance of complex and quality work. It’s good to have both of these options at hand for the job.
Types of power tools by type of el. safety
You can find the following classification:
- 0 - this includes tools in which all parts are energized, components for grounding are completely absent;
- 0I - also all parts with current, while there is grounding and working insulation;
- I - power tools with the same component as the first two (the presence of insulation and grounding contact);
- II - all parts are energized and with good insulation, but there is no grounding;
- III - voltage no more than 50 V, the power tool is powered by a safe low voltage.
Another subdivision method
Today, the entire tool is divided into classes. On them it is easier to understand what to choose and how to work. The main types of power tools by appointment:
- Industrial
- Heavy duty
- Professional
- Hobby.
Each of them has its own characteristics and features. In addition, it is worth understanding how they work. Some are able to perform tasks for a long period of time, while others will have to give a break or recharge. Before making a purchase, it is worth considering this. Otherwise, the service life may be reduced.
Industrial
This is the name of tools that work for a long time without breaking. Most often they are attributed to the conveyor process, so they do not turn off for 15-18 hours. Such units are characterized by a long service life and reliability. In addition, repairs are often not required. There is one feature. Power tools of this kind usually work in confined spaces, which means they must be completely environmentally friendly.
Ergonomics is another requirement for such installations. It is not possible to call Industrial multifunctional devices, because they have limited capabilities. People with special education are allowed to them, so the level of security is low. Before starting work, it is worth creating certain conditions for operation:
- the desired voltage level in the network and the maximum reliability of the wiring;
- humidity indicator in the room;
- temperature at which the device will not fail;
- dust level.
Only in this way can tools fully work and perform assigned tasks. If the conditions are not observed, the devices can quickly fail, although it is unusual for them.
Heavy duty
Translated from English, this means "heavily loaded." This includes such types of tools that can be compared with the first in their characteristics. Although there is a significant difference, there is no need to create certain conditions. This is achieved by changing the design:
- additional protection against moisture;
- a fence for capturing dust;
- high level of impact resistance.
But the positive aspects do not end there. You can use consumables and parts from simpler models during operation. They can not be found on the shelves of simple shops, as this is a specialization of a narrow spectrum. If necessary, they are made and delivered by special order.
Professional
This is the most popular type of professional tool. In work, they are used actively. With their help, the most durable units and parts are created. The whole structure is highly reliable during operation. In addition, these devices have the following properties:
- assembly accuracy;
- high level of work and a long period of operation;
- ease of maintenance;
- adaptability to severe loads and adverse conditions.
Devices can function without stopping for up to 9 hours. This is enough for one shift for workers. In terms of environmental indicators, this tool is inferior to the first two, but not significantly. But ergonomics are lower, since the period of work is not more than 9 hours. Although there is a big plus - this is an increase in the level of security during the execution of work. So, not only masters can work with them. When a failure occurs, it will be easier to find a replacement part than to the first two types of power tools.
Hobby
Many need a household power tool. Hobby can be amateur, garden, garage. And it is not often used (from period to period). From this it is clear that he will not be able to work for a long time without stopping. When assembling, do not use high power engines, since the output does not require a high coefficient of efficiency. But the devices can work up to five hours during the day. However, minor breaks are made in the process so that the unit does not fail.
There are significant disadvantages. So, much attention is not paid to ergonomics, namely the protection of the user. But many people use these types of tools, since they do not require additional skills and experience. The entire arsenal of units should not be subjected to harsh operating conditions, because most often one person works with it. But the level of maintainability is low. Maintenance is not required (unless a personal inspection before starting work).
These are the main types of power tools, into which all the commercially available composition is divided. From this list, everyone understands what exactly he needs to purchase. Although there is another group worth knowing about.
Universal devices
Today on sale you can find such power tools that have many diverse functions. In addition to their main purpose, they are able to do something additional. This is not even one operation, but several. This may include a screwdriver, because it: tightens the screws, makes holes, can act as a construction mixer, but subject to high power. A drill is another representative of such a group. His abilities are great - a punch, screwing in screws, creating holes. In such electrical equipment, you only need to change the nozzle and add or reduce power.
But giving preference to units that have many functions, do not forget about a minor minus. Not always additional work will be performed efficiently. And to understand why this happens is not difficult. Any process implies its speed, power and duration. From this it is seen that sometimes it is necessary to have highly specialized electrical installations in order to achieve the desired result and quality in work. Performing actions to the limit of their capabilities, the tool will simply fail or the consumable will break.
Conclusion
So, we examined the types of power tools and their scope. Types can be very diverse. Also, devices differ significantly in price. In such a situation, it is clear that in some works you cannot do without a highly specialized power tool. Not every such unit is required constantly. In this case, you can take the device for a while or for rent. But working with it will turn out an order of magnitude better and faster. The main thing you need to know: choose the right type of power tool. The scope is what you need to pay attention to.
