Rechargeable grinding machines: features and comparison of models

Rechargeable grinders – a kind of portable equipment that allows you to significantly expand the range of use of Bulgarians. As a rule, such models are compact, possess modern design and suitable for cutting metal, wood, stone for insignificant depth.

But among miniature devices, there are real “working horses”, complying with the requirements of the professional market and allowing long-term continuous work for a long time.

Main characteristics

The basic characteristics of grinding machines on the battery are quite standard, they allow even with a small market analysis of such equipment to obtain an idea of ​​the requirements for the acquired tool. Among the important parameters it is worth highlighting a number of characteristics.

  • Supported disk diameter. As a rule, it varies in the range of 115-125 mm.
  • Battery Duration. The most effective is the lithium-ionic versions of 18 V with a resource reserve by 5000-5500 a * h.
  • The number of spindle speed per minute. What it is lower, the more intense consumables are spent, the stock of the circles will have to replenish regularly. The indicator is not lower than 8,000 rpm – for rechargeable equipment, the indicator is quite impressive.
  • Motor design type. Brushless ushs are more expensive, but in the long run, it turns out to be more profitable acquisition. Collector (with brushes) is easier by design, more often fail.

In addition to other parameters, when selecting rechargeable equipment, it is worth clarifying the possibilities for its operation in a different range of atmospheric temperatures, climatic conditions.

Varieties

All rechargeable grinding machines can be divided into household and professional options. The first have ultra-compact dimensions and quite expected set of characteristics: batteries at 3 a * h, supported disk sizes up to 115 mm and low weight – on average about 1.5 kg. Budget value makes such mini-options for ESM optimal for home use. But on the duration of work without recharging, they are significantly inferior to the analogues. On average tool enough for 10 minutes of continuous grinding or cutting. The depth of immersion in the material does not exceed 25-28 mm.

Professional models also lose full-size wired counterparts in the parameters of the supported disks – It reaches 125 mm against 180/230 mm in large Bulgarians. But in the rest of the mobile devices there are many advantages that allow you to fully control the whole process, work without a break for 30-45 minutes depending on the type of operation performed. Vectors are common among professional models. They are focused exclusively on metal cutting, equipped with special pulse acb.

Advantages and disadvantages

The ushm on the battery has a number of advantages and disadvantages. It can be attributed to its advantages:

  • High mobility – can be used where there is no access to the network;
  • Minimum weight – the lightest models have a mass of 1.5 kg, without creating a significant load on the brush of the hands during the work;
  • Small noise level – in comparison with network models, the difference is very noticeable;
  • Comfort associated with the lack of wires and restrictions on moving on the object;
  • The most simple design, to cope with the start and debugging which may even unprofessional.

Among the most frequently mentioned deficiencies of portable Bulgarians, you can allocate a high cost, significantly higher than similar indicators of network models. In addition, the range of products in this case is significantly limited and is presented from all popular brands.

Rating popularity

Make a rating of battery levels on the market is not difficult. Conducting a comparison, it can be noted that there is a significant difference between professional and household appliances. The market leaders include several popular models.

  • Metabo WB LTX BL 125 Quick Equipped with a brushless motor, modern electronics to ensure work safety, charge indicators. Innovative Akb LiHD holds a charge for a long time, believing one of the best on the market, has a swivel design. At the same time, 9000 rpm idling enough to demonstrate high performance.

  • MILWAUKEE M18 CAG125XPDB-0 Differs in a brushless motor, professional class and modern filling. Batteries are usually proposed to buy separately – the manufacturer claims capacity of 5 a * h. Among the advantages can be noted the presence of a filter, a quick nutrition nut for changing the equipment, the presence in the configuration of an additional handle.
  • Dewalt DCG 412 M2 Equipped with a protective bracket, a battery of 4 a * h, when working it develops to 7000 rpm at idle. The model provides an additional two-position handle, there is a start button block.

As for direct wood machines, here, when performing work, it is not the number of spindle revolutions, but the ability of the equipment to cope with the tasks set before him. Straight USM is designed for closing the surface to the desired smoothness. Among her differences – a special shape of the body, resembling a classic corver. The fastening of the equipment is performed ahead, in a special nest, the range of possibilities depends on the status of the model – household or professional.

Rechargeable EMPs for woodwork have power up to 800 W, while cope with the basic set of operations. For long grinding on a large area, it is better to choose a more powerful professional equipment in 2000 W, supporting work with disks with a diameter up to 150 mm. For accurate material processing, you will need a small snap, the wider there will be a choice of opportunities, the easier it will be to achieve the desired goal. Among the leading brands, Metabo, Makita, Bosch can be highlighted here.
