Which tool to choose: renovator abo engraver, reviews and differences

Thanks to one multifunctional power tool, you can perform many different jobs, which with the usual set of tools may require professional skills and a lot of time. In this article we will talk about the capabilities of engravers and renovators, consider positive and negative feedback, as well as about, what you need to pay attention to when choosing tools.

By multifunctional electrical equipment means oscillatory tools based on the oscillations of the working part. They are usually called "renovator", more precisely, universal tool for repairs, finishing, restoration work. But there is no exact name, some manufacturers or stores call them: oscillating grinding tool, vibrating universal machine, universal cutter, multimaster and even vibrating.

The principle of operation is similar to vibratory grinders, in other words - processing of material by means of vibration of a working part. But the possibility of installing different nozzles, just makes this equipment a universal device. Dozens can be produced with just one renovator, including: cutting and cutting of almost all sheet materials; cut plastic parts, wood, drywall, ceramics, brick or iron; dismantling, stripping the surface from plaster, silicone, putties, glue; cut a rectangular hole, a slice in an inaccessible place or an exact slice; grout, emery grinding or grinding, etc.. d.

Varieties of multifunctional tools

According to reviews, to date, the most popular solution is the already described renovator. It can be in a set of home tools or replace them a whole range. To be an additional tool during installation work, products, repair. It can even be the main tool, if you do not have a large amount of work, and you face non-standard and different tasks.

Some manufacturers have gone even further in multi-renovation: the intermediate nozzle is connected to the electric drive, which makes it possible to change the principle of operation of the equipment. The change of specialization is due to variable heads, each of them corresponds to a specific type of tool - the renovator, drills, etc.. d. The end nozzle of the intermediate head can make it move forward, vibrate or rotate. These kits are called "multi tool", their capabilities depend directly on the configuration.

Experience of dentists in the extraction of material from the "details", fragmentation, grinding and micromilling can be completely transferred to the world of the master. This is a set of tools, having the traditional principle of rotation, called "rotary engraver". These tools are designed for small volumes of work and are perfect for cases, if accuracy and precision are important. Possibilities of home use also depend directly on a set and a complete set of nozzles.

Electric chisel, perforator, jackhammer in miniature belong to the section "percussion engraver". Used for minting and engraving. It, definitely, the least popular version of the multi-tool.

Advantages and differences of renovators

A lot of work, which are made by hand tools, differ only in pendulum or reciprocating motions. If you make them electric, but reduce the amplitude of the working area by increasing the frequency, then we will have all the benefits of a hand tool, and at the same time increase productivity. As a result:

  • ease of work, without "professionalism";
  • high quality and accuracy of materials processing;
  • tool safety and work safety (Moreover, unlike high-speed tools, which create the effect of ejection of equipment and material);
  • a small amount of dust, minimal workmanship;
  • opportunity to carry out non-standard works;
  • the ability to work with materials of any elasticity and hardness.

Nozzles and complete set of the renovator

Every specific job can be done with the help of a renovator, only if a certain nozzle is included. There are two common ways to choose a renovator:

  1. We buy a renovator in a set with nozzles, which provide versatility of works and the widest range of use. With the growth of tasks and practice, we increase the range of nozzles separately or buy a ready-made "box" in the set.
  2. We choose the renovator on the basic parameters without a set of nozzles or with the minimum set, and nozzles are purchased separately for a specific task. According to experts, this approach is more "professional": funds are invested in the main unit and several specific nozzles. Money is not spent on nozzles, which you will not use. This method is suitable for savings, when you specifically know, what to do. The disadvantage of this option is that, that the purchase of nozzles one by one will cost more.

Regardless of the approach you need to pay attention to:

  • The presence of positive feedback about the tool.
  • Availability or availability of nozzles for the selected model of the renovator.
  • What nozzles are needed for your work, whether they are in the set, on sale.
  • Availability of a set of adapters to fix the equipment of other companies or the ability to purchase this adapter separately.
  • Versatility of the seat on the renovator, the possibility of installing nozzles from other manufacturers.
  • In some sets of nozzles the total number of nozzle heads in a set and is described, usually, this number is "caught up" by nozzles of grinders.
  • Location in the trunk for storage of nozzles, purchase a separate trunk or save and provide storage by other means.

The most popular method of fixation, when the nozzle is fastened with a screw (under the hexagon). More expensive provides quick replacement of nozzles with a lock of special design.

The description of any nozzle indicates its purpose and materials, which will be possible to process (ceramics, tree, glass, concrete, plastic, etc.). Nozzle sockets or "sharpened" for a particular manufacturer, or can be universal.

The most popular nozzles for household use

Segmentation disk. It is made in the form of an incomplete circle, with part of a segment of complex shape or with a truncated edge. Some manufacturers complete the tool with solid discs. Most often, they all specialize in the type of materials and the task. The disk is rasp, grinding and polishing, vigilant.

Delta platform. This nozzle gives the chance to carry out works on grinding. Taking into account the manufacturer, may vary in size. Abrasive grinding sheets are fixed to this nozzle.

On inexpensive models, usually, solid platform. On more expensive, which have a system of connection of vacuum cleaners - with holes for dust removal. Do not forget, that on the established emery sheets there should be the same apertures.

Triangular nozzles with a diamond crumb for sawing are also made, carbide, for polishing.

Saw blade. Has a complex or rectangular shape. Gives the opportunity to perform immersion or other sawing of various materials. It is selected for the material and the task.

Depth limiter. Element, which makes it possible to make cuts of certain sizes and depths, even when it is impossible to visually control the depth of cut.

Shaber. Often called a scraper, scraper, chisel. Removal of the remains of construction mixes and glue for cleaning of surfaces is used, trimming and dismantling of coatings, clearing seams, etc.. d.

With the popularity of renovators and consumer feedback, the sphere of their use also increases, improvement of nozzles, expansion of applied tasks. Now you can see universal holders on the market, they make it possible to include in the kit many new forms of cutters, tips, shlif-nozzles, saw blades, etc.. d.

Features of the choice of the renovator

Before purchasing, pay attention to the location of the buttons, the form of the device, availability of protection and hobbies. The reverse function can add comfort in work, smooth start system, the possibility of connecting a vacuum cleaner or an additional handle.

Although during the renovation of the dust does not go to the pillar, but the quality of work decreases, which is all the more relevant when grinding. The ability to connect a vacuum cleaner in this case is not superfluous, but simply a necessity. How to connect the pipe, convenient or not to operate and hold the tool, as far as the review is visible?

Without a smooth start, it is difficult to crash into the responsible part, without error.

Carrying out non-standard and complex works, you will get tired quickly with heavy equipment. Therefore, when buying a renovator, focus on reviews, the weight of the device and your endurance. But remember that too, that lighten the tool with plastic easily, but to make plastic parts durable harder. Quality winding and motor armature will always be massive.

Renovator power and power

These tools are powered, like many, from batteries or the mains. All the advantages and disadvantages of battery packs, generally suitable for all electrical equipment, visible here, but with a slight clarification: even network models do not require much power. Therefore rechargeable, although a little worse, but not globally. You can forget about power choices. Select the battery model according to the criteria of service life, amenities and reviews.

According to the level of power, all existing models can be divided into the following groups:

  • To 100 Watts - for unpretentious and easy tasks. From cardboard to plywood there will be no problems, as well as with plastics and linoleum. Small in volume and simple operations on grinding and stripping are quite feasible.
  • 100-200 Watts - the average level of loads, suitable for periodic use and many rare household chores.
  • 200-300 Watts - allows you to work with any materials without overload, specified in the instructions. Is a semi-professional tool.
  • Over 300 Watts are durable equipment, which works easily with any materials. Usually used for professional purposes.

Oscillation angle, frequency and speed

Revolutions are more important for multi-tools with a nozzle, which is used for rotation. For renovators the main level of fluctuations of a working zone is more important. For different types of work and materials, the optimal frequency is also different. Therefore, the mode of speed control or oscillation frequency is of paramount importance.

On different products, the adjustment is stepped or smooth. The minimum limit for renovators is significantly different, and the maximum limit is usually no more 22 000 moves / minute. When cutting metals and solid materials, minimum frequency limits are set, for plastics - medium, for plaster and soft wood - maximum, as well as for grinding works.

Indicator, not adjustable by the user - the angle of oscillation (often indicate - oscillations). It differs in each model insignificantly: 1.3 – 1.7°. Some manufacturers do not indicate the amplitude from the middle position, and full, in this case, this figure looks like this: 2.7 – 3.3°. None of the manufacturers substantiates the information on the amplitude, although easy to understand, what exactly it affects: on the size of the stroke of the working part of the nozzle. The higher the amplitude, more or longer in the diameter of the nozzle, the longer it is to move the part. The choice of tool is almost not affected by this parameter.
