The best cordless grinders (angle grinders)

Angle grinders are often also called simply "grinders", because the first of them came to us from Bulgaria. There are network and battery grinders - the first need to be connected to the network, and the latter work autonomously. We will consider the features of the second category further, and at the same time highlight the five best models of cordless angle grinders.

Pros and cons of cordless grinders

Cordless grinders are gaining more and more popularity along with an increase in power and a decrease in the average price. They have several advantages over networked ones:

1. Portability - for use, you do not need to have a nearby power grid, it is this factor that often becomes the main one when choosing a rechargeable grinder, because often you have to use it in those deprived of electricity places.
2. It's much more convenient to work without wires - the rechargeable grinder allows you to work in any hard-to-reach places.

In general, using a cordless grinder is easier and more pleasant than a heavy and noisy one. Due to its relatively low power, it will not try to jump out of hand during operation. But it also has disadvantages compared to the network one:

• The cost is higher with comparable quality.
• More weight due to the battery.
• Lower power.
• The battery power runs out quickly - rarely are there models that can work on one for more than an hour.

With the help of a network tool, it is much better to cut metal and generally carry out work of a large volume and of high complexity. The rechargeable one is needed primarily for those who use the grinder only from time to time.

By what parameters to choose a battery grinder

There are a number of criteria by which you can choose a grinder from the models on the market. This is:

• Disc diameter. There are several options: the 115 mm disc is suitable for grinding and small work; on 125 it is the most widespread, since most of the household work can be carried out with it; discs for 150 are used for cutting metal pipes, bricks, concrete - they are practically not found on battery models, and even more so discs for 180 and 230 mm.
• Speed - the speed at which the disc rotates. For most household needs, 7,000-10,000 rpm is sufficient.
• Battery capacity and operating voltage - they determine how long the grinder can work autonomously and how productive it will be.
• Weight - here everything is clear anyway: the lighter the tool, the easier it is to work with it.
• Additional useful functions. Among the latter, it can be noted: "soft start" (at the beginning of work there are no abrupt jerks); self-balancing of the disc, which reduces the level of vibration; automatic regulation of its rotation speed; dust removal system. A technologically advanced grinder is much more pleasant to use than the simplest tool without all these functions, which means that work with it will go faster, and the result will please you more.

The best manufacturers of cordless grinders

Several manufacturers have recommended themselves best of all: among them the German Bosch - its products are expensive, but very reliable; Japanese Hitachi and Makita are able to compete with the Germans in reliability, although they are slightly inferior, like the American DeWalt. These are the companies that lead the market. In addition to them, the Swiss DWT can also be noted, Ryobi products are popular in the segment of inexpensive battery angle grinders, and in Russia, cheap Interskol grinders are also added to the list of leaders.

Among all the battery grinders presented in domestic stores, we have identified the five best. They are well suited for everyday tasks, although more powerful network models are better for major repairs and metal cutting. The grinders in the list are sorted by price in descending order - accordingly, their characteristics are also falling.

1. Bosch GWS 18-125 V-LI

Most notable for this model is its low power consumption. The kit includes a spare battery, and the charging time is only half an hour - that is, with the help of a Bosch grinder, you can work without interruption.

2. Metabo W18 LTX125 Quick

The Metabo company is known for its reliable and efficient angle grinder, equipped with powerful LiHD lithium batteries. These batteries are equipped with a heating control system and overload protection, and their capacity is the best on the market. The W18 LTX125 Quick model is also equipped with them, and therefore works for a long time without recharging. True, even this is not always enough, and there is only one battery in the kit, so if you need a tool for voluminous work, you will have to buy a second one or constantly interrupt to recharge.

The disc diameter of the model is 125 mm, the rotation speed is up to 8,000 rpm. She weighs a lot - 2.6 kg. The device is well thought out, pleasant to use and easy to maintain. So, removing and installing filters is very simple, you don't need to disassemble the grinder itself, the battery can be rotated - and this helps a lot when working in cramped conditions. The motor is brushless, electronically protected against overload and completely dustproof, so there is no need for maintenance. There is a mechanical brake, which is not often found among tools with a 125 mm disc. The model costs about 11,000 rubles - considering all the conveniences, this price can be called justified.

4. DeWalt DCG412N

DeWalt is a well-established brand that produces, among other things, reliable mid-range devices such as the DCG412N. At a cost of about 8,000 - 9,000 rubles, this model has a good set of functions. The grinder weighs quite a lot for a battery - 2.9 kg, but this is compensated by a good weight distribution and balance - you can work with one hand.

The rotational speed of the disk is up to 7,000 rpm, therefore, in terms of capabilities, this model is inferior to the previous ones - for example, when cutting metal, the battery sits down very quickly. Nevertheless, if it is not planned to solve too complex problems with the help of this grinder, in terms of price-quality ratio, it will be a good choice.

5. Ryobi R18AG-0

This model takes primarily a low price - it can be purchased for about 4,000 - 4,700 rubles. At the same time, Ryobi is a Japanese manufacturer, and its products are significantly superior in reliability to cheaper Chinese or Russian counterparts. But one should not expect high performance: the disc diameter is only 115 mm, and its rotational speed is 6,500 rpm, there are no batteries in the kit. The grinder can operate on both modern lithium and outdated cadmium-nickel batteries.

The weight is small (2.2 kg), the case is quite reliable, it is convenient to hold the grinder. If it is needed only for grinding and cutting with a depth of no more than 28 mm - this model will be a good option, in other cases it is worth looking at more powerful ones.

Popular questions

Are cordless grinders suitable for grinding metal?
Powerful models are suitable for this. So, from those presented in the top above, with the help of the first three grinders, metal can be grinded and cut. The fourth, in theory, gives such an opportunity, but it is better not to use it, because the engine is rather weak and the battery runs out quickly. In general, if the need to grind and cut metal occurs often, it is better to use a more powerful network grinder.

conclusions

In recent years, cordless grinders have become powerful enough and cheap enough to be purchased instead of network grinders in many cases. This applies mainly to situations when they are planned to be used only from time to time for small volumes of work.
