Comparison Intertool DT-0523 vs Elektromash VMR-570

The electrical power consumed by the tool during normal operation. Usually, the characteristics indicate the power at the maximum speed / frequency of movements of the working nozzle.

Usually, the higher this indicator, the more intense the tool can act on the material being processed, the better it is suitable for difficult conditions (large volumes of work, hard materials). At the same time, note that high power significantly affects energy consumption; in mains-powered models (see below), this puts strain on the wiring, and in battery-powered models, it requires the use of bulky and heavy batteries and significantly reduces battery life. Yes, and this parameter significantly affects the dimensions, weight and price of the tool itself. Therefore, it is worth choosing a model according to power consumption, taking into account the specifics of the work for which it is planned to be used: for example, it hardly makes sense to purchase a high-performance professional tool for minor repairs around the house or in the country.

Specific recommendations on the optimal power values, depending on the type of tool and the purpose of its use, can be found in special sources.

The vibration frequency of the working head, provided by the tool in the renovator or delta grinding mode (for more details on the modes, see "Replaceable heads"). For different types of work and different materials, the optimal frequency values \u200b\u200bwill also be different; therefore, when choosing, it is worth consulting the reference literature or a specialist and making sure that the selected model will provide the required number of oscillations.

In some models, this parameter can be adjusted - this makes the tool more versatile.

Types of nozzles supplied with the tool.

— Delta platform. Grinding nozzle with a characteristic triangular shape. It is an obligatory element of equipment for tools with the function of a delta grinder (see "Interchangeable heads"), however, it is also often found in renovators (see "Device").

— Segmented disk. A nozzle in the form of an "incomplete" disk — a circle that has no segment. Such a nozzle is only suitable for processing using vibration, and therefore it is found exclusively in tools with a renovator function (see "Device", "Interchangeable heads"). At the same time, the shape of the nozzle allows you to work with both the front and side parts, which gives you freedom of manoeuvre.

— Chaber. A scraper usually means a plate of a rectangular (or close to it) shape. Such a nozzle is one of the most popular in renovators (see "Device", "Replaceable heads") due to its versatility: it is suitable for scraping, cleaning surfaces, cutting, etc. In addition, the scraper is traditionally used as a regular nozzle for electric chisels .

— Saw blade. Specialized nozzle for sawing various materials. Its design and method of operation may vary depending on the specifics of the tool: for example, in electric jigsaws (see "Replaceable heads") the saw blade is designed to move back and forth and looks...like a characteristic strip, in renovators it looks like a narrow plate, etc. .

— For stitching seams. Nozzle for processing joints between tiles, bricks, etc. to give them a neat appearance. It is worth considering that the shape of the jointing can be different (convex or recessed, straight or rounded, etc.), respectively, and nozzles for such work can have a different shape; specific features should be specified separately for each instrument model.

- Sheets for grinding. Sheets for grinding and polishing stone, wood or metal products on a special plate with fastening to the executive body of a multifunctional tool. They often have a triangular shape; sandpaper or diamond coating is used as the material for their working surface.

Note that these are far from all types of nozzles that modern universal tools can be equipped with, but only the most popular ones. In addition to them, other devices may be included in the kit — for example, a variety of sanding sheets. And the “set of nozzles” option is indicated for tools (mainly engravers, see “Device”), the equipment of which includes several dozen devices; in some models, this number may exceed one and a half hundred.

The presence of an additional handle in the design or delivery set of the tool (it can be either built-in or removable).

This handle makes it easier to hold the tool with two hands, which is important when processing hard materials that require significant effort — or in delicate work, where precision and maximum control are important. Note that, as a standard, it is done based on right-handed users, however, many tools allow you to change the location of the handle, for the convenience of "left-handed" work.

The presence of a case or cover in the tool kit.

A case is a hard container, a cover is a soft one; the main differences between them are due to this difference in materials. However, the purpose of both devices is the same: they provide ease of storage and transportation. This convenience is provided both by additional protection (in the case of covers — from dirt, in the case of cases — also from hits and shocks), and by the fact that all attachments and additional accessories, usually, are placed inside the cover/case, thereby reducing the risk of losing any of these items.

The weight of the tool can be indicated according to different rules: some manufacturers take into account only the body without a nozzle, others — with a standard working nozzle, for multi-tools (see "Device") the weight of the main unit without a replaceable head, etc. can be indicated. These points are usually specified in the specifications or detailed documentation.

In the case of a power tool, weight has a dual meaning. On the one hand, the smaller it is, the easier it is to hold the unit in your hands during long work and the more convenient it is to carry out fine, accurate processing. On the other hand, a light tool is less stable and has an increased tendency to jerk, which is important under difficult conditions and hard materials.
