There is a wide range of power tools on the market, but not everyone knows how to make the right choice. Therefore, it is worthwhile to understand the classification and purpose of products before starting. Each requires its own equipment and tools. Understanding this issue is not so difficult. And today we will look at the types of power tools, purpose, application and features.
Main differences
There are several different classifications. The very first - by appointment.
- To create holes, various recesses and threading, there are: drills, screwdrivers, rotary hammers, jackhammers and thread cutters. There are other options, but this list is the most common and frequently seen on the market.
- For wood finishing. These are planing, sawing, and milling. This includes a jigsaw, a planer, a variety of saws, milling cutters and a grinder. These are the main types of power tools that a person needs. If needed, you can buy moresomething.
- To make the part flawless, it is ground and polished. It is not always possible to do this manually. So, there are files, grinders and wall chasers. With them, the part becomes flawless in a short period of time.
- There are also such 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 home appliances. There are such in every house or apartment.
There are different types of hand power tools. These are the ones that can be carried and used anywhere. They can be used depending on the need, which is very convenient. But there are also those with which you can do some work, but you will not be able to transfer it all the time.
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 high-quality work. It's good to have both of these options at hand to get the job done.
Types of power tools by type of email. security
You can find this classification:
- 0 - this includes tools in which all parts are live, there are no components for grounding;
- 0I - also all parts with current, while there is grounding and working insulation;
- I - power tools with the same component as the first two (insulation and ground contact);
- II - all parts are live and well insulated, but groundedmissing;
- III - voltage not more than 50 V, the power tool is powered by safe low voltage.
Another division method
Today the whole tool is divided into classes. They make it easier to understand what to choose and how to work. The main types of power tools by purpose:
- 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 complete tasks for long periods of time, while others will need to be given a break or recharged. Before making a purchase, it is worth considering this. Otherwise, the service life may be reduced.
Industrial
This is the name for tools that last 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 distinguished by a long service life and reliability. In addition, repairs are often not required. There is one feature. Power tools of this type usually work in enclosed spaces, and therefore must be completely environmentally friendly.
Ergonomics is another requirement for such installations. Calling Industrial devices multifunctional will not work, because they have limited capabilities. They are allowed to people with special education, so the level of security is low. Before starting work, it is worth creating certainoperating conditions:
- the desired voltage level in the network and the maximum reliability of the wiring;
- Indoor humidity indicator;
- temperature at which the device will not fail;
- dust level.
Only in this way will the tools be able to fully work and perform their tasks. If the conditions are not met, devices can quickly fail, although this is unusual for them.
Heavy duty
Translated from English, this means "heavily loaded." This includes such types of instruments that, in terms of their characteristics, can be compared with the first. Although there is a significant difference, there is no need to create certain conditions. This is achieved by changing the design:
- additional moisture protection;
- dust guard;
- high impact resistance.
But the positives don't end there either. It is possible to use consumables and parts from simpler models during operation. They cannot be found on the shelves of ordinary stores, 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 kind of professional tool. They are actively used at work. With their help, the most durable components and parts are created. The whole structure is highly reliable during operation. In addition, these devices have the followingproperties:
- assembly accuracy;
- high level of performance and long service life;
- easy maintenance;
- adaptability to serious loads and adverse conditions.
Devices can function non-stop for up to 9 hours. This is enough for one shift for workers. In terms of environmental performance, this tool is inferior to the first two, but only slightly. But the ergonomics are lower, since the period of work is no more than 9 hours. Although there is a big plus - this is an increase in the level of safety during the period of work. This means that not only masters can work with them. In the event of failure, finding a replacement part will be easier than with power tools of the first two types.
Hobby
Many need a household power tool. Hobby can be amateur, garden, garage. And it is not used often (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, high-power engines are not used, since a high efficiency index is not required at the output. But devices can work during the day up to five hours. However, minor breaks are made in the process so that the unit does not fail.
There are also significant drawbacks. So, much attention is not paid to ergonomics, namely the protection of the user. But these types of tools are used by many, since additional skills and experience are not required. The whole arsenalunits should not be subjected to harsh operating conditions, because most often one person works with him. But the level of maintainability is low. Maintenance is not required (except for a personal inspection before starting work).
These are the main types of power tools into which the entire 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 a wide variety of functions. In addition to their main purpose, they are able to do something additional. This is not even one operation, but several. This includes a screwdriver, because it: tightens screws, makes holes, can act as a construction mixer, but subject to high power. The drill is another representative of this group. His abilities are great - puncher, screwing, 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 slight minus. Not always additional work will be performed qualitatively. And to understand why this happens is not difficult. Any process implies its speed, power and duration. From this it can be seen that it is sometimes necessary to have highly specialized electrical installations in order toachieve the desired result and quality in work. Performing at the limit of its 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, the devices differ significantly in price. In such a situation, it is clear that in some works one cannot do without a highly specialized power tool. Not everyone needs such a unit all the time. In this case, you can take the device for a while or rent. But work with him will turn out much better and faster. The main thing you need to know: choose the right types of power tools. Scope - what you need to pay attention to.
