Renovators: what is it, what is it for and what types are there?
The multifunctional renovator tool appeared at Fein half a century ago. Initially, this device was used to repair the bodies of cars and trucks. Ten years ago, the patent ended, this wonderful tool began to be produced by various companies that found wide application for it: it is in demand in many different areas.
What it is?
The renovator in Russia was presented in the popular show “Shop on the Sofa” 10 years ago. In another way, the renovator is called "multitool"; in translation from English, tools means a tool. This device is advantageously distinguished by the fact that various attachments can be attached to it, with which you can do a wide range of works:
- grinding;
- cleaning;
- scraping;
- drilling
- creation of grooves and grooves.
The renovator is based on the principle of oscillation (German Oszilation
The device itself consists of a sturdy case, to which you can attach a variety of attachments-attachments. The nozzles are working elements that are in direct contact with the material.
Now let's move on to the pros, cons and, in general, talk about the capabilities of the renovator and areas of use.
If we talk about the negative countries of this instrument, then this is an opportunity to work with small volumes of material for a short time.
What is it needed for?
The purpose of the renovator finds its place in everyday life for the widest possible use. If you need to do some minor repairs, for example, remove a nail that is sticking out of a block, or remove a "blot" of old dried glue. The multitool can even cut steel sheets or pipes, but to a strictly limited extent. For such work, it is still better to use a turbine.
If it becomes necessary to cut a sheet of plywood according to a drawing, he will cope with such work as easy as shelling pears. But if the volume is too large (10 square meters), then it is more rational to use an electric saw for cutting. The renovator is convenient to use in places that are difficult to access:
- narrow space between pipes;
- deep and narrow niches;
- attic floors and so on.
Craftsmen know and appreciate this feature of the instrument. Oscillatory movements of the renovator can reach 330 per second, they do not have large amplitudes, therefore, devices are in great demand in finishing during construction.The multitool is good for making small grooves and grooves in the tree. With the help of a special nozzle, such an innovative tool can be used to remove old coatings (varnishes, paints, primers). The renovator is suitable for removing old tiles or porcelain stoneware from walls and floors, but such a chamber tool is unsuitable for large volumes of work (processing large areas).
The renovator is appreciated for its versatility and compactness. On the farm, he saves a whole "gentleman's set" of tools, which are optional:
- grinder;
- jigsaw;
- grinder and much more.
Principle of operation
The renovator works on the principle of oscillation, that is, the nozzle moves along the axis by 1.6-3.1 degrees back and forth. The frequency is high, more than 14 thousand vibrations per minute, that is, at least 250 cycles occur per second. The tool can be immersed in soft material up to 10 mm without any interference. The power plant of the unit is an electric motor, it can be found in any power tool.
The essence of the renovator's work is in the functioning of the eccentric, which is located at the extreme point of the shaft, it creates vibrating impulses in the working area. It is exposed to considerable loads, therefore, it is usually immersed in an oil substance so that active abrasion does not occur. The renovator is also remarkable in that it is possible to use a huge number of different attachments. This fact makes the multitool a versatile unit that can be used in a wide variety of areas.
Powerful renovators are characterized by a high torque impulse, the performance of such devices is noticeably higher. When working with dense material, such "machines" do not get very hot. For small volumes, renovators with a capacity of no more than 200 watts are sufficient. If it is necessary to process porcelain stoneware tiles, then devices from 350 W must be used here. Vibrating tools can only be an add-on; they will never perform as efficiently as tools that function by means of a reciprocating mechanism.
The deflection angle of the vibrating element is only 1.6 degrees, the devices are safe and cannot harm the health of the worker. The maximum number of vibrations in multitool can reach up to 600 cycles per second, with similar indicators, even concrete and porcelain stoneware can be cut.
Setting the vibration frequency is an important functionality that must be taken out separately, combined with the trigger. In this case, it will be possible to change the operating mode in a second.
Views
The electric multi-tool is divided according to the power principle; an electric multitool can be:
- network;
- rechargeable.
Rechargeable devices are compact, necessary, for example, for plasterboard works, when clips should be installed under the ceiling. The lightweight instrument can be held at arm's length for a long time.
The disadvantage of battery packs is that chargers are quite expensive and have a limited lifespan. Over time, batteries, "exhausted", stop working.
In chargers, the most reliable are lithium-ion batteries, the energy in such cells is stored longer, their service life is longer. The disadvantage of such batteries is that it is completely forbidden to discharge them to zero, otherwise the battery life is significantly reduced. It is recommended to take into account the fact: at negative temperatures, lithium-ion batteries cease to function. The capacity of a charger is measured in ampere-hours or watt-hours, the less the device costs, the weaker its battery.
The more sections in the battery, the more guarantees that it will work more reliably for a long time. There are models where there are massive batteries, sometimes such devices are extremely necessary when you need to do an impressive amount of work in a short period of time. Most often they buy network units (in 80% of cases); Various attachments are very popular. There are high-power renovators, respectively, the size of the devices is much larger.
You can even work with them on concrete, large-sized mechanisms are rarely needed at home.
Rating of the best models
According to user reviews, rating reviews are compiled every year, including those of renovators. Last year, the best domestic renovators were:
- "Enkor" MFE 400E;
- "Interskol" EShM-125270E - this Russian manufacturer is widely known for inexpensive and high-quality tools not only at home, but also abroad;
- Bosch GOP 10.8 V-LI is considered a good model from Bosch - these devices are versatile, reliable, durable.
Makita is a long-time rival of Bosch in Japan in the field of power tools - also excelled last year with the Makita TM3000CX3 and Makita BO5041.
The most comfortable to use are mechanisms in which you can use the change of attachments without using a key. The Bosch corporation from Germany is actively promoting just such units on the market. Keyless bits are simple and reliable. They are not unscrewed randomly during work operations.
The most popular and simplest models are renovators from the Enkor company:
- MFE-260 has a power of 265 W;
- MFE-400E has a power of 410 W.
In the first case, the manufacturer sells just a tool, in the second case, the kit contains a small set of unpretentious attachments.
The second model is more functional, capable of doing a large amount of work, while the price of the "400" is comparable to the "260"
It makes sense to buy the first option if you need a compact unit. Renovators from Skil and Ryobi corporations are well known in the market. For example, the Skil 1472 LA model has a 200-watt engine and shows itself in the most positive way.
The Ryobi RMT 200S model is more expensive, but has more performance (sold in a special backpack).
The "king" of renovators is considered a priori Bosch PMF 250 CES. The price of this "toy" is almost 2 times more, but there is (and this is a big plus) keyless fasteners for various attachments.
The Bosch company is known on all five continents, the products of this corporation are reliable in operation, costly, and are distinguished by their durability.
If funds permit, it is better to buy a good branded item from Bosch or Interskol than to spend even larger sums later on repairing a bad multitool.
Another well-known manufacturer from the USA is DeWalt. The DeWalt renovator is distinguished by its reliability in operation and productivity. It is convenient to use such a unit in works:
- removal of old sealant;
- dismantling of wooden structures;
- trimming laminate and parquet;
- grinding of porcelain stoneware panels;
- sharpening of tools;
- compaction of concrete mass.
The power of the power plants of most units (they are professional) from this company does not exceed 360 watts. All mechanisms have a function of protection against unauthorized switching on and off.
Components
A large number of different sets of attachments largely determines the versatility of the multitool. Each individual operation requires a special size nozzle; these useful elements can be installed at different angles. Manufacturers usually detail the purpose of each attachment and how best to work with it. The most popular ones are:
- files;
- knives;
- blades;
- abrasive elements;
- all sorts of spatulas and so on.
It is important to remember that the tool that is present in the renovator cannot replace, for example, a victorious or corundum chisel, which can process ultra-strong reinforced concrete for a long time.
Attachments are often sold in a certain thematic layout:
- plumbing;
- putty;
- auto;
- repair of windows.
It is best to use attachments that are attached with a quick-release method. (an invention of the Bosch company). It is comfortable to work with such a tool: the lever is turned, the nozzle is instantly fixed. Thanks to adapters, the tooling can be quickly replaced, therefore it is possible to buy different accessories from both Bosch and Makita.
For more serious work, semi-professional sets of equipment are used, we will list the most popular ones.
For plumbing work, models of fairly large power are required with mandatory vibration frequency control. When the power control is in sight, it is easy to handle the following nodes:
- pipe thread;
- chamfering;
- expansion of the seams;
- cleaning surfaces from solution, sealant, old primer;
- cutting tiles or porcelain stoneware;
- drilling holes.
For interior decoration, the multitool is used as an accessory. It is most often used in sawing wood, plasterboard, plywood. It will also be necessary to install drywall frames, grind the planes of walls and ceilings. Dismantle various bars, metal elements, pipe scraps and so on.
When repairing a car, it is often used for cutting various body metal and PVC elements. In auto repair shops, renovators are needed quite often, they should always be at hand. Car attachments are sold in large separate kits.
Many models can be equipped with an additional handle, which is very convenient in some cases.
Additional examples of different hard surface tips:
- special "soles" of a triangular shape are used for polishing;
- for chipping concrete surfaces, you can find special nozzles with a victorious or diamond coating;
- many different attachments for working with wood;
- there are special scrapers that allow you to remove dried substances (PVA glue, primer, etc.);
- blades sharpened on both sides for cutting linoleum and PVC boards.
When the renovator is working, you can connect a vacuum cleaner, then microparticles will be almost completely absent in the atmosphere of the room. Another undoubted advantage of renovators: their work is not associated with the appearance of large quantities of small particles (fragments, shavings) that could fly in different directions. In a private household, this feature contains undeniable advantages.
How to choose?
Choosing for a home is a serious matter that requires maximum awareness. The tool should work properly for more than one year, while performing the maximum number of different tasks. First of all, you should pay attention to the power indicator of the power plant of the device, as well as the number of revolutions. If you have to process hard materials (metal, concrete, marble), then the number of revolutions can be low.
The tool of different brands has advantages and disadvantages. It makes sense to buy branded items, even if they are more expensive. Any eminent brand carries an informational message: the thing is reliable, it will function for a long time without any complaints. The best renovators are produced by corporations:
- Interskol;
- Bosch;
- Makita;
- AEG;
- Hammer.
Let's consider the choice of a multitool using two models as an example:
- "Enkor MFE-260";
- "Diold MEV-0.34".
The first "representative" has a low power, but the speed is noticeably higher, it is contraindicated to work with such a unit on concrete, it will quickly burn out. The second "machine" has great power, it can interact with solid materials for a long time.
If the renovator has a low power, then the attachment will "stick", the work will be unproductive. Units that have a motor with a power of more than 360 W are quite suitable for solid materials. If the power plant "outputs" up to 210 W, then the mechanism will heat up significantly, which will adversely affect its service life. Such mechanisms do a good job with such materials:
- drywall;
- plywood;
- PVC plates;
- plastic.
In the renovator, the function of the speed regulator is important, which must be present in a conspicuous place. Selecting the optimal speed allows you to extend tool life and more efficiently solve material processing problems.
