Do-it-yourself renovator repair tch td 950w

One of the interesting novelties of recent years on the market of household and professional tools has become a renovator or multitool. It is an electrically driven device capable of performing a large number of technological operations required in the construction, repair and processing of hard materials. Its versatility is given by interchangeable attachments of various shapes and purposes, performing oscillatory movements with a high frequency with a small amplitude of movements. This article is devoted to their brief description and comparison of their functionality.

Attachments for multifunctional tools carry the main load during operation, so their choice should be taken seriously and carefully. Usually, one or another of them is present in the kit of the sold renovator, which can be mains or rechargeable. If the set of accessories sold at a reasonable price along with the multitool is too large, then this indicates a low quality of their manufacture. It is better to purchase a unit of a well-known brand with several main incisors, and then buy in addition those of them that you really need in your work. In this case, the design and performance of the part must correspond to a specific purpose and strength characteristics of the material being processed.

Do not be lazy to ask the seller for the accompanying documentation and make sure that the product is marked accordingly.

Since the attachments for the renovator operate in the high-frequency vibration mode, they must be securely fixed in the fastening unit of the working head of the tool. For this, in its body there are curly cutouts, which for different manufacturers of multitool may not coincide in shape. It is imperative to pay attention to this when buying. Fastening can be carried out using:

• hex key;
• special quick-fix clamp.

Exists universal adaptersallowing the use of products from different manufacturers. The differences between the multi-tool attachments relate to the shape of the part, the base material used and surface coatings, and the device of the cutting edge. Their design is optimally suited to a strictly defined type of processing and in most cases allows you to work in awkward places or in confined spaces. Along with the multifunctionality of the tool, this is its main advantage.

Owing to oscillatory movements with sufficient strength of the nozzle, it is possible to perform various types of operations on materials with moderate hardness and even on metal. The design of the cutters is varied, but the maximum practical application is for parts of the optimal shape for each type of work.

Scrapers are used for cleaning surfaces from old coatings and binders, which include:

• paint;
• glue;
• sealant;
• polyurethane foam;
• cement splashes and other contamination.

They have a flat or curved shape with a straight or arched working edge. After such processing, a flat surface remains, which can be prepared for finishing.

This nozzle is characterized by a high surface hardness. With its help you can:

• clean the seams between tiles and panels;
• to embroider cracks;
• remove slugs of cement mortar;
• cut concrete, stone, ceramic products.

It is not designed to carry out a large amount of work, for which it is better to use a specialized high-performance concrete tool... But for a one-time stripping and cutting in hard-to-reach places, such a disc is best suited.

Grinding plates are used for:

• cleaning surfaces from dirt and rough leveling;
• fine grinding;
• polishing products.

The type of processing depends on the grain size of the abrasive layer, which can be applied to the part itself, but more often they are used for this replaceable sandpaper sheets... The shape of the plate has elongated protrusions that allow you to fully sand areas along the walls and in the corners.

The nozzle of this shape is used as a saw... It is made of high quality alloy steel. With its help, you can make precise and accurate cuts on:

• wood;
• plastic;
• other construction materials, including non-ferrous metals and low-quality steel grades.

With such a disk, cutouts are made in drywall, protruding elements are flush cut, the ends of the workpieces are processed or oblique edges are made.

Sometimes for a multi-tool they use straight or curly files elongated shape, allowing you to cut in hard-to-reach places. If a specialty store does not have a nozzle of the desired configuration, you can try to make it yourself.

As a blank, you can take fine-toothed hacksaw for wood with wide saw blade. It will make several durable attachments, since the saws are always made of high quality steel. After marking, the contour of the part is cut out using an angle grinder.

It is hardly possible to accurately reproduce with your own hands at home planting holes of a complex configuration for installation in a renovator, therefore it is easier to saw off the corresponding section from the old nozzle that has exhausted its resource... To connect it to a new plate, two holes with a diameter of about 2 mm are drilled in it.

Doing the same in the hardened metal of the saw will be more difficult. Additional steel tempering operation, which consists in heating the back of the workpiece with a gas burner to a crimson color with slow cooling in air. Then, after marking, two mating holes are drilled in it with the same drill. After making sure that they match exactly, increase the diameter of all four holes to 6 mm.

If you want to curved nozzle, bending of parts is performed using a vice and a locksmith's tool. After connecting them with short M6 bolts with counter nuts, the file for the multitool is ready for work.

A multifunctional tool, called a renovator, and intended for the production of household and construction work, is becoming more and more in demand not only among home craftsmen, but also among professional builders. The very idea of ​​a safe and easy-to-use tool operating at a high vibration speed is good, and all kinds of attachments for the renovator significantly expand its functionality, allowing you to perform a wide variety of work. What are the attachments for the renovator, what do they look like, what are the specifics of their use and how to make the right choice?

Construction, installation and repair work involves the processing of surfaces of various types - wood, ceramics, metal, concrete, etc. The multifunctional renovator tool has no restrictions on operation with any one material: thanks to the appropriate attachments, a household or professional craftsman has a full scope of work :

• cutting wood, plastic, soft metal;
• removing the floor covering;
• cutting and removing a thin layer of cement mortar;
• polishing of metal, stone and other hard surfaces is performed using felt nozzles of various degrees of abrasiveness;
• cutting into materials of various kinds at shallow, medium and maximum depth for the nozzle;
• cutting drywall, cutting soft materials - rubber, carpets, cardboard, insulation;
• scraping ceramic tiles, etc.

The accessories for this tool are made only of high-quality materials, and the configuration of a particular nozzle depends on the profile of work and the materials for which it is intended: the saw blade, in particular, has a segmented shape, the equipment for removing the solution is in the form of a drop, sanding sheets for wood processing - deltoid shape. Often, manufacturers, in addition to individual units, offer a set of nozzles: when purchasing such a kit, you can be sure that when carrying out installation, repair or construction work, everything you need will be at hand.

Each nozzle has mounting holes, due to which it is tightly fixed on the hexagonal holder of the tool itself (nozzle sockets can be universal or specialized - only for the tool of the same manufacturer). After installing the nozzle, the bolt with the spring washer securely fixed to it is tightened with a hex wrench. The last step of a fairly simple and quick installation will be to check the correct position of the nozzle and the reliability of its fixation.

Wood is one of the most common materials in construction and finishing work, and therefore wood attachments for a renovator, depending on the specific operation with wood, are different:

• for cutting wood, a spade-shaped, rectangular or other complex-shaped cutting disc, called a saw blade, is useful - its functions include plunge-cut or other sawing not only of wood, but also of other materials (plastic, soft metal, etc.);
• a segmented saw blade has the shape of an incomplete circle, often with a cut edge or part of a segment of a complex shape, sometimes manufacturers complete their multifunctional tools with a full circular disc;
• for cutting work with wood, you may also need a depth gauge - with it you can make cuts of a certain size even without visual control, which will be especially important for hard-to-reach places;
• the rasp disc and sanding pad are used for rough processing of wood, for removing large burrs.

For work on metal (steel, aluminum, copper, etc.), the same types of attachments are suitable as for wood (segmented saw blade, plunge-cut saw blade), but designed specifically for metal working. The material for such nozzles is a composite bimetal BIM - it is distinguished by its strength and wear resistance, which makes nozzles for a metal renovator durable, reliable and safe.

Sanding sheets of various grain sizes allow you to quickly and efficiently sand metal products - you should pay attention: only red sanding sheets are used for working with metal, black and white ones will be too soft and will not give the desired result (they are used for hard stone surfaces, glass, varnished coatings ).

Ceramic is a rather fragile material, therefore, for users of the renovator, special attachments are offered for working with it:

• for high-quality cutting of ceramic tiles, a segmented saw blade with abrasive (diamond) dusting should be used;
• for cleaning tile joints, a segmented nozzle without an abrasive coating is used - the size of the saw blade allows you to choose the equipment suitable for very thin or, conversely, wide joints. In some cases, it is convenient to use a plunge-cut saw blade for the same purposes;
• removal of mortar and grouting in the most inaccessible places is possible with a nozzle for removing mortar of a unique drop-like shape: the sharp tip will be effective for working in the inner corners, the round part of the tooling - along the course of the tiles.

Concrete work most often consists in high-quality preparation of concrete surfaces for subsequent operations. In this case, the following concrete nozzles for a multifunctional renovator will come in handy:

• deltoid sanding pad will allow you to remove mortars or tile adhesive not only from concrete walls, but also from other hard surfaces;
• Scraping concrete surfaces can be greatly facilitated by using a scraper attachment: this attachment effectively removes old paint, glue, silicone and other building compounds. The scraper for the multi-cutter is divided into hard and soft, it can vary in size, most often it is made of high-carbon steel for soft HCS materials;
• a segmented saw nozzle without an abrasive coating will allow you to quickly and efficiently make grooves in aerated concrete for communications.

Among the most popular models of multifunctional renovator tools, Bosch should be noted: blue tools are designed for professional work of a significant volume, green ones - for household work. The sets of nozzles for the renovator, in turn, contain everything you need: the offered 37 nozzles for wood, metal, ceramics, concrete allow you to carry out construction, installation and repair work in a short time, with high quality and without significant efforts on the part of the master.

There is still controversy surrounding this issue on the forums, although the multifunctional tool (MFI) began to gain popularity in 2008. Can it really be used as a full-fledged replacement for a grinder, a saber and circular saw, a jigsaw and a hand chisel, or a renovator, like a can opener, will be needed in rare cases. Let's sort it out in order.

The Renovator uses the principle of oscillation, or simply oscillations. The universal cutter shakes the installed attachments at high speed and minimum amplitude. In the video, you can see how their cutting edges are blurred and trembling. It is the rigging and high-frequency vibrations that make the renovator a multifunctional tool.

Here are some of the capabilities of MFIs:

• cable channels are channeled to them;
• cut installed sewer pipes and internal wall fittings;
• remove the influx of plaster, glue, polyurethane foam, clean off the paint;
• peel off linoleum from the floor;
• cut nails and screws flush;
• take out grooves in wood and drywall from the end and mortise (submersible);
• cut sheet elastic materials and soft seals;
• trim plinths, fillets and cornices in place;
• embroider the seams on the laid tiles and cut the tiles themselves;
• trim installed door frames;
• sand difficult surfaces and hard-to-reach internal corners;
• sharpen tools.

Let's clarify now - what a renovator is. Professionals define it like this: a tool of last resort. It is indispensable as an auxiliary construction tool in the final stages of work or when reworking. And for home use, the multitool will completely save you from buying several power tools.

According to the class, renovators are divided into professional and household ones. Expensive models have the ability to connect to a vacuum cleaner and have a flashlight that illuminates the work area. Professional power tools let you get more work done in one go and last longer.

According to the type of power supply, the power tool is divided into mains-powered and battery-powered. One of the advantages of the multitool is its light weight and small size. The battery, unfortunately, increases both. The reduced engine power of battery-powered cutters has little or no effect on functionality.

Mains powered renovators consume between 170 and 600 watts. For cordless models, the power is determined by the battery voltage. Low power models up to 100 W are used for cutting soft and non-sticky materials.To work with metals and ceramics, models from 200 W are required. At home, it is enough to buy a medium power tool - up to 250 W or up to 18 W for rechargeable devices.

The frequency range of oscillations at idle speed varies from 5000 to 22000 rpm. There are instruments with a fixed frequency and adjustable smoothly or stepwise. Metal, ceramics and resilient materials are processed at low frequencies, while wood, drywall or plastic is processed at medium to high frequencies. It is important that the tool has a smooth start - this will allow you to start cuts without errors.

The multi-tool allows you to quickly move from one type of work to another. For this, the type of fastening is important - quick-clamping or key. With a quick-release, the nozzle is instantly fixed in place, and with a key, it is tightened with a hexagon bolt. It is also worth paying attention to whether it is possible to use attachments from other manufacturers, with or without an adapter, or not. For some models, you can change the angle of attachment of the files if the work is to be done in hard-to-reach places.

MFIs are optionally completed with cases for tools and accessories. Systems for connecting a vacuum cleaner, cutting depth limiters, protective pads against touching the canvas, adapters for using attachments from different manufacturers are sold separately. Also, on the multi-tool, it is possible to install an additional handle, like on a drill.

A battery with a charger is not an obligatory part of the package, and when purchasing them separately, you need to make sure that they match the voltage.

Consumables for renovators are polishing attachments, knives and files for scraping and cutting. There are different nozzle shapes for different tasks and materials:

• triangular plates for self-adhesive sanding or velcro polishing sheets;
• carbide triangular soles and tongues for grinding and polishing;
• semicircular or triangular cutting nozzles with diamond or carbide chips for sawing metal and slitting concrete and tile adhesive;
• submersible blades with a width of 10 to 70 mm with teeth at the end for wood or metal;
• scrapers (scrapers) for scraping off glued linoleum or the remnants of "liquid nails", silicone and polyurethane foam;
• knives with a double-edged blade for chipping walls or cutting carpet, linoleum, cardboard, foam, fiberglass;
• attachments for attaching narrow cutting flat and spiral blades and threads, as in hand jigsaws.

If you remember that renovators are not designed to perform a large amount of work, then it is difficult to find negative characteristics in them.

Renovator cuts are obtained with smooth, sanded edges. The multitool is indispensable for cutting "sandwiches" from materials of different densities.

There is very little dust when working with a multitool, and it does not fly in all directions. And with a connected vacuum cleaner, you can do minor repairs at home without preparing the premises.

The first renovators were used to remove plaster in traumatology. It is difficult to injure yourself with the tool. And there are no fragments scattering like shrapnel when the canvases are damaged.

The choice of a multi-tool depends little on its class and comes down to consumables and equipment. For the home, it is quite possible to buy a household appliance without a kit and select equipment for it only for the planned types of work. If you do not overload the equipment, it will serve no worse than a professional one. And consumables from top manufacturers in home use are becoming almost immortal.

The most popular professional tools and accessories are made by Bosch, Makita, DeWalt, Dremel and Fein. Renovator, Intertool, Enkor and Ritm devices are popular among inexpensive brands. Household knives and saws should be chosen with the BiM marking as the most versatile.

Renovator what is it? There are things that you don’t feel you need until you start using them. Multi-tool is one of them.See photos, specifications, reviews and feel free to buy. The multitool is not that irreplaceable - it expands the capabilities of familiar construction tools and serves as a lifesaver.
