Possibilities of renovator - multifunctional tool

Relatively recently, in the outfits of professional and home craftsmen, a universal tool appeared, called the renovator or multitool. Its feature is the numerous nozzles, with the help of which one can mechanize a large number of technological operations used in construction, repair and other fields of activity associated with painstaking and monotonous work. This multifunctional tool does not compete in performance with highly specialized models of saws, grinders or grinders. Its advantage lies in the ability to perform fine and precise work in hard-to-reach places.

Design and principle of operation

Any power tool has an engine connected by means of a drive with a working element acting in one way or another on the workpiece. Such a mechanism usually performs rotational or reciprocating motion. At the heart of creating a renovator, in contrast to traditional devices, there are two basic principles.

1. Using one motor with many easily replaceable nozzles, which extends functionality multitool compared to any of the specialized models of the usual type.
2. The use of high-frequency oscillations with a small amplitude, which allows work extremely accurately and accurately.

Most renovators have an elongated body to which, for the convenience of the operator, ergonomic handles can be attached. The internal device consists of an electric motor, the rotating shaft of which is associated with an eccentric. Its vibrations are transmitted to the capture with a nozzle fixed in it.

The design usually provides the ability to position the working surface of the tool at different angles, depending on the conditions of use and the type of operation being performed.

Vibrotool is experiencing high loads during operation, so its most critical components are made of high-quality steel, and all friction parts are always lubricated. The most advanced models are equipped soft starter, allowing to minimize the peak of negative impact on the unit, falling on the initial moment of work.

The strengths of renovators include:

• a wide range of operations performed;
• ease of use, based on a careful study of the design and low weight;
• high reliability with long service life;
• simple control and effective overload protection;
• full safety for the operator.

Renovator classification

The electric multitool is primarily characterized by power. According to this indicator, the following types of devices are distinguished.

1. Home appliances up to 100 watts, designed for the periodic processing of thin and pliable materials.
2. Professional modelsthat consume more than 300 watts, which can be used intensively when exposed to hard surfaces, including work on concrete, non-ferrous metals, cement or ceramic substrates and strong plastics.
3. Semi professional devices, occupying an intermediate position according to their characteristics.

Depending on the power used, the hand-held electric multitool can be either mains or battery. The first is convenient to use on an equipped workplace. The second is characterized by high autonomy, which limits only the battery capacity.

For most models, manufacturers have provided the ability to control the frequency of oscillation. In this switching can be carried out stepwise or smoothly.

In what situations is required multitool

The scope of the universal cutter is directly related to the set of supplied nozzles, which are also easy to purchase additionally. Renovator can do a large number of technological operations, which include:

• dismantling old wall, floor or ceiling finishes to a solid foundation;

• cleaning seams;
• performing figure cutting on materials that do not differ in extremely high hardness;
• production of technical channels of non-standard form;
• milling of small blanks;
• rough fitting of the mating parts;
• cutting sheet materials;

• cutting pipes or structural elements located in hard-to-reach places;
• jointing cracks;
• cleaning, leveling and grinding of any surfaces;

• sharpening cutting tools.

All these types of work can be done in other ways. The decision that it is more profitable to apply: jigsaw or multifunction tool, accept, based on specific conditions. For cutting large volumes in a convenient position, you need a powerful specialized unit. In the case of short-term use, and even in a hard-to-reach place, a mini tool is required. An industrial grinder works well on straight sections of a large area, but it is not capable of cleaning the surface near corners. Renovator will not do it so quickly, but extremely high quality and neat.

Types of used nozzles

Renovator work depends on type of nozzle used: the more they are attached to the instrument, the higher its capabilities. The most common types of work items:

• semi-circular blades used to clean seams and cracks;
• scrapers for removing old finishing coatings installed at different angles;
• jagged semicircular cutters, used as a vibratory saw on wood, drywall and other pliable materials;
• grinding plates of various shapes, allowing work in corners and other difficult areas.

For the reliability of holding the nozzle in the latch, its body has shaped cuts, which can be different for different manufacturers. Correctly fix the working plate in the device allows hex key or special clamp.

There are universal adapters that adapt the products of most manufacturers to each other.

What you need to know when buying a renovator

In 2017, the sales of renovators continued to grow. This means that the consumer appreciated the advantages of this tool and began to actively use it in economic activity. Such a device can not be attributed to cheap acquisitions, so its purchase must be treated very responsibly. If you decide to choose a suitable model for your home, try to follow simple rules:

• better to buy a tool from famous manufacturer;
• the apparent savings from the purchase of cheap baits will result in additional costs for their frequent replacement;
• if you need to work with a powerful device in a workshop or at home, stop your choice on network model;
• if, during trial switching on of a renovator, it works with an unpleasant vibration for hands and quickly heats up, discard this option.

The correct choice of the multitool and its accessories should always be based on a precise understanding of the nature of the work ahead and personal feelings from contact with the instrument. Only in this case, it will bring you maximum benefit and satisfaction from the results obtained.
