Angle -grinding machine for home use. Network angular grinder 115 mm

How to choose a corner grinder?

The angular grinding machine is useful for cutting and polishing blanks made of metal, wood or stone, as well as for stroke and removal of old coatings. To make it easier to decide on the choice, we will consider the types of corner grinding and the scope of their use.

  • The network corner machine depends on the presence near the outlet. Useful for prolonged use.
  • The battery angular grinder works from lithium-ion or nickel-cadmium battery. It is useful when work is required in the distance from the network.
  • A pneumatic angular grinder works on a compressor or compressed air supply system. Used for professional construction work or factory production.

Disk diameters

It is the diameter that will determine the sphere of work with a corner grinder. Consider the most popular options:

  • 115 mm the smallest diameter of the disk for cutting parts up to 30 mm thick. Useful for grinding small areas, cutting nails or thin sheet metal. common diameter, cut the workpiece to a depth of up to 40 mm. The most universal size, light and at the same time productive. Suitable for removing a layer of paint, removing corrosion or stripping welds. Not the most popular disk size, cuts the part up to 50 mm thick. Convenient for dismantling pipes, cutting reinforcement. The second most popular diameter, cut depth from 40 to 60 mm. Used to make grooves, as well as for cutting brick and concrete. The largest disk size, cuts the workpieces to a depth of 80 mm. It is used on heavy construction work for cutting rails and thick pipes, asphalt or paving slabs.

Corner grinder which company choose

Tips for choosing the size of the cutting disk

It is the diameter of the disk that is the key factor that determines the area of ​​work performed by the tool. It is worth noting that the planting diameter for circles has a standard size. 22.2 mm. But the larger the diameter of the cutting circle, the higher the speed of rotation and the power of the corner grinder. The minimum diameter is 115 mm, the maximum possible is 230mm.

The diameter of the disk is selected depending on the thickness that will need to be cut. Based on the fact that not all, but only a part of the circle protruding outside the tool can be used as a working one, it is necessary to pay attention to the size of the case. For example, if the case has a width of about 60 mm, then when using a disk of 125 mm, it is not difficult to understand that only half of its surface will work. That is, it will be possible to cut out the material with a thickness of not more than 35 mm, but in reality even less. 30 mm. After some time, the cutting surface of the disk is stuck, which will significantly reduce this indicator. With the help of such simple calculations, the necessary disk size is selected. But it is strongly recommended to use circles of larger diameter than allowed by technical documentation.

To make it easier for you to navigate, we will analyze in more detail the types of Bulgarians based on the size of the disk:

  • 115 mm angular grinder. the minimum size for the simplest work. Most often used for grinding, since cutting is very inconvenient for such a size. A smaller diameter implies a lower weight, which means a lower power. Weight lies in the range of 1.5-3 kg, and power is not more than 1000 watts. But the “small” corner grinder has the maximum speed-10-11 thousand.rpm. There is the possibility of capturing both one and two hands. The size of the tool does not affect the price, and such a compact tool can have both a small value and vice versa. There are models equipped with many additional functions for professional use.
  • 125 mm angular grinder is the most popular model. It has sufficient power, the optimal weight and size, affordable cost for ease of work. In any store, the most extensive selection of grinding or cutting circles with a diameter of 125 mm. This is an optimal tool for home use, if it is not planned to cut too thick details.
  • 150 mm angular grinder. unlike the previous model, does not use such demand, although it is an excellent alternative option for home use, if you need not a small, but not a big model. It is convenient to perform both grinding and upable work. But many argue that the purchase of a separately small one is a more convenient solution. 125 mm and large. 180 mm angular grinder. This tool has an average power of 1000-1500 W, an average rotation speed-8-10 thousand.about./min and medium weight-3-5 kg. “Golden mean” for home craftsmen.
  • 180 mm angular grinder is a suitable option for construction work. The depth of the cut will easily cope with the cutting of brick (though it is necessary to cut it all the same on both sides), a thick pipe and other elements. This means that doing smaller work with such a tool may not be quite convenient.
  • Corner grinder at 230 mm. the maximum provided for by manufacturers. It is called the “large” angular grinder. It has a more significant weight-5-8 kg, a powerful engine-1500-2000 W, speed-6-8 thousand speeds.about./min. They are equipped with two handles. the posterior stationary and lateral with the possibility of installation from different sides of the case. They differ in high cost, which justifies the number of functions. With its help, gross work is performed, where force is necessary, for example, cutting metal pipes, stroke of walls for wiring, etc.D. For small work, such models are absolutely not suitable, even grinding seems to be a small. But with large repairs or construction work, they will be as possible.

After analyzing the five possible sizes of this tool, it is clear that everyone has its own advantages and disadvantages. If you are engaged in construction work at a professional level, then the best solution for you will be to purchase two corner grinders. Small. 125 mm for accurate work and medium. 180 mm. If you have repairs or construction, then a tool is suitable for 150 or 180 mm.

When you decided exactly what size of the instrument you need, you can proceed to the choice of the following parameters:

  • The power of the corner grinder is the main indicator of the tool performance. A possible power range varies from 0.5 to 2.7 kW, and the increase in power is not directly proportional to the diameter of the working disk. The performance indicator should be selected according to the same principle as the size. depending on the degree of complexity of the upcoming work and their duration. It is clear that using the maximum diameter of the working circle, it is necessary to choose models with a power indicator of about 2 kW to ensure high speed and increase continuous operation time. But for small tools with a minimum disk diameter, you sometimes need high power, especially if you have to continuously clean the hard welds for several hours. A small tool with a power indicator of 0.5-0.9 kW is considered domestic and is quite suitable for a small volume of work, which does not imply prolonged cutting of pipes or grinding concrete surfaces. For more difficult work, models with a capacity of 1 to 1.5 kW are suitable, which are classified as professional. To perform construction work, it is preferable to corner grinder with a capacity of 1.3 to 2.7 kW.
  • Rotation speed angular grinder lies in the range from 6,000 to 15000 about./min. It is believed that the higher this indicator, the faster you can perform grinding work or clean the surface from rust and other contaminants. In practice, this indicator for each tool is selected individually depending on its weight and is the best. The only thing you need to know is that the angular speed of rotation depends on the diameter of the working disk. Therefore, for large Bulgarians, it is preferable to have a function of adjusting the number of revolutions. When erasing the working edge, this indicator must be reduced, thereby normalizing the speed of angular rotation. For domestic use, there is enough tool with a minimum indicator. 6000 about./min. If there is a construction or work that includes polishing wooden surfaces or making a wood fence, you will need a model with an indicator of 7000-11000./min. To clean up car bodies and other metal surfaces, choose a tool with an indicator of 15,000 about./min. Such can often be seen per hundred.
  • The weight of the tool determines the duration of the work. Do not forget that when working, a load on the hands and back is created. The lightest tools, the weight of which starts at 1.2 kg, is suitable for daily work lasting no more than 4 hours. The average corner grinder weighing from 3 to 4 kg are suitable for work for 2-3 hours every day. For hard work, it is necessary to choose more overall models that will cope with the task faster and do not require much effort from the operator. Their weight is 6-9 kg.
  • The number of handles. corner grinders are one.handed and two.handed. This immediately catches your eye when visiting specialized stores. All models have the main handle, which is screwed at the spindle itself and has the ability to rearrange on different sides of the case. This makes work with the tool equally convenient for both right.handed and left.handed. The second pen is either the case itself, or an additional handle at the end. This makes it possible to hold the tool with both hands if necessary. The choice of the number of handles is based again on the nature of the upcoming works. It will be equally convenient to perform update work both with one handle and two, and grinding work is dangerous to perform a one.armed tool. During operation, the corner grinder can strongly bring it and even a physically strong person will hardly hold it. Therefore, choosing powerful models for grinding, look only at two.armed. Corner grinding ground for fine grinding of low power can be one.armed. The main handle should preferably have protection for fingers in large tools and expansion in the upper part of small. This will prevent the sliding of the tool from tired or sweaty hands. The auxiliary handle should have a mushroom shape and in an ideal case to be able to twist in several positions. This will do work with a corner grinding of the most convenient. Both handles must have a rubberized coating.
  • Tank or battery capacity. Gasoline models have a tank volume from 0.7 to 1.5 liters. If you have the opportunity to carry an additional canister with fuel with you, then this indicator does not matter. Battering angular grinders have a battery capacity of 2-4 a/h. Thanks to this, the speed of rotation of the spindle reaches the indicator up to 11000./min. Accordingly, the larger the capacity, the greater the time of the tool. For short.term work, there is enough minimum indicator.
  • Air supply and air supply. for pneumatic models. Speed ​​is important in maintaining high speeds. This indicator reaches from 100 to 540 liters/min. The larger the diameter of the disk, the higher the feed rate should be. The pressure at the same time reaches 6 to 6.5 atmospheres.

This video explains the features of the tool

Among the variety in the market, Japanese, German and American ones are considered the best grinders. But in recent years, the domestic segment has also advanced well, the tools of which can be found at a completely budget price. Of the many companies for home use, you can make a certain rating of the Bulgarians:

These companies on the market are already enough time and managed to prove themselves as manufacturers of high.quality tools.

Of all the companies, it would be wrong to choose 2-3 and make a corner grinder rating for them, since different models have its own purpose, so you should not compare a professional tool with the house for home. They differ not only by purpose, but also. There are reviews of users who will help distribute tools as popular:

One of the budget samples that produces the domestic market. This tool has that diameter of 230 mm and power 2600 W. Rpm. reach 6500, which allows you to work with solid materials. This model is connected to the network, and also has a speed adjustment and a smooth launch mechanism.

Of the advantages, one can distinguish: a sealed body of magnesium, which protects against overheating, dust and external damage, affordable price, as well as a three.position handle. This model is very heavy because of its size.

This is a corner grinder that is collected in Asia from German details. Well suited for home use. Its power is 900 watts, and the maximum circle is limited to 125 mm. Speed ​​of 11,000 rpm and small size allow you to work with ceramic details or iron.

If there are doubts about which angular grinder of 125 mm to choose, then you can stop the choice on this copy. Advantages: wide functionality, good equipment (spare brushes, casing, spare handle and the key to replace the circle), simplicity of control, small weight, price. Of the shortcomings, one can distinguish that the length of the cable is only 2 meters, so you have to use the extension cord.

A German tool that is suitable for any task and is a frequent choice among professionals. Its power reaches 1200 watts. The ability to change the revolutions allows you to configure the tool for yourself, and their maximum number is limited by 11,000.

The size of the disk of this model is limited to 125 mm. Smooth launch and adjustment of the position of the handle make an angular grinder more convenient, and blocking the work when overloading and jamming will help to avoid a breakdown of the tool.

This is a Japanese production model that is well suited for home use. She has a battery, which is able to work up to 30 minutes on one charge. It has a circle of a circle of 115 mm and speed speed up to 10,000.

The disadvantages include greater cost, as well as overheating of the mechanism that occurs when using a circle of more than 1.4 mm thick, since due to small power it is strongly strained.

Before choosing the tool, you should carefully familiarize yourself with its capabilities and reviews, as this will help to find out for what purposes it is suitable for, but for which no.

Criteria for choosing a good corner grinder

Before buying, you need to study the main characteristics of the tool. For the selection of the best Bulgarians, the diameter of the disk, intensity and revolutions, all kinds of protection are taken into account. It is also necessary to understand how much equipment will consume electricity, it is better to choose the most profitable option with its savings.

Disk diameter

The disk is considered the main supplies that is responsible for cutting, polishing and cleaning. Manufacturers offer 5 varieties:

  • up to 115 millimeters. the minimum size is used for grinding and small works;
  • 125 millimeters. a popular diameter of a household tool, drinks to a depth of 40 mm, cuts almost all types of materials;
  • 150 millimeters. used for brick, concrete surfaces, metal pipes;
  • 180 millimeters-designed for repair and construction procedures.

Interesting! A 230 millimeter.diameter disk is suitable for equipment intended for commercial purposes. The weight of the equipment in the collected form depends on its size.


At the expense of it, the stable functionality of the apparatus is ensured, it helps the equipment work without a break. For household purposes, equipment with an intensity of 600 to 900 watts is used. With complex or long.term events, you will need a tool with indicators from 1.5 VC.

angle, grinding, machine, home, network, angular


The speed of spindle rotation depends on the volume of the disk:

note! Good equipment has a manual regulator that allows you to reduce the speed of spindle rotation.

The number of handles

The parameter provides convenience and safety, devices are with one or two handles. The first option is found in home and commercial corner grinding, the second. in severe versions for mass processing of surfaces.

Smooth start

Provides a phased increase in the number of disk rotations, reducing the network load when starting equipment. The lack of a starting jerk prolongs the life of the gearbox.

Automatic maintenance of revolutions

Functionality is necessary to reduce the frequency of rotation of the disk during hard work. It is used to grind metal products or when cutting concrete surfaces.

Re.launch protection
