How to choose an angle grinder for your home or garden correctly

In order to make the right choice of a grinding machine that meets all the necessary requirements, it is necessary to determine the tasks that will be assigned to it. Most importantly: determine what you will cut with the angle grinder, and how often.

As practice shows, household angle grinders with a working disc size of 125 mm and a power of up to 1.5 kW are best suited for home and summer cottages. Such machines are lightweight and lightweight, easy to operate, and equipped with additional features. For a wheel diameter of 125 mm, many additional attachments have been released that turn the angle grinder into a universal tool.

The table shows the comparative characteristics of some brands of angle grinder from different companies on the electric tool market.

Budget angle grinder (angle grinder) Caliber MSHU-125 / 955E, 950W power and speed control

I greet everyone who looked at the light. The review will focus, as you may have already guessed, about an angle grinder Caliber MSHU-125 / 955E, powerful enough for its class, with a power of 955W, a circle diameter of 125mm and smooth speed control. This model is interesting, first of all, for its low price and high characteristics, namely, increased power, compact dimensions, as well as the ability to adjust the speed over a wide range. As far as I know, in the models of this class (circle 125mm) and price range, there is no speed control at all, and most models do not have a comfortable ergonomic handle. In the review, as usual, there will be a detailed description and disassembly, so anyone interested, you are welcome under the cut.

Purchase background:

General view of the angle grinder Caliber MSHU-125 / 955E:

– Model. MSHU-125 / 955E

Equipment:
– angle grinder Caliber MSHU-125 / 955E

The angle grinder is supplied in a light box made of heavy corrugated cardboard:

The box contains the company logo, the appearance of the product, as well as some features of the model. The main performance characteristics are indicated from the end of the box:

Since Caliber is a Russian trade mark, the instruction is completely in Russian:

Appearance:

Angle grinder Caliber MSHU-125 / 955E is a power tool designed for cutting, grinding and cleaning products made of metal, stone and other materials. It is made in the usual dark green color for the manufacturer:

The layout is standard for this type of device: the slewing gear is located in the front, the collector motor in the middle, and the handle with controls at the back. There are openings for air intake and outlet from the ends of the case:

The main controls are housed in a slim, ergonomic handle, namely, a latching start button and a speed control. Unfortunately, it is not rubberized and is made of matte plastic, a little rough to the touch:

Even in spite of the absence of rubberized inserts, in wet hands the grinder lies confidently in the hand and does not slip during work. I would like to note that for most users the version with an ergonomic grip will be preferable, since with this version the hands get tired much less than with the version with an “integrated” grip, in which it is part of the body. The only caveat of this design is that compactness suffers somewhat, so who often works with an angle grinder in narrow places, it is better to look at the option with an integrated handle. Also, do not forget that with small wedges of the disc, it is much easier to hold a sander with a longer handle than with an integrated.

One of the interesting features of this model is the adjustment of the spindle speed, which allows you to perform a variety of operations from cutting to metal polishing with a few reservations. To do this, there is a special regulator on the back of the handle that allows you to smoothly change the speed from 0 to 11000 rpm (position from 1 to 6):

Unfortunately, the regulator does not have the function of maintaining the set speed (without feedback), so the speed “floats” depending on the pressure on the tool. From my own experience, I can say that it is possible to polish with this grinder, but for a very short time, since at low engine speeds, the cooling air flow is small and the tool may fail from overheating.

On the body there is a sticker (nameplate) with the model name, main characteristics and serial number, judging by which, the grinder was produced in March 2017 (the last 4 characters):

The slewing gear is enclosed in a metal housing that looks like a magnesium alloy:

The wall thickness is decent, small protrusions on the body serve as a kind of stiffeners:

On the rear side of the gearbox there is an outlet for the outlet of cooling air, as well as a button for stopping the spindle:

The set of accessories is sufficient and consists of the following elements: a removable side handle, a protective cover and a steel key for mounting the circle. The wrench is strong enough and is designed to install / remove the disc by tightening / unscrewing the pressure flange:

The protective cover, unfortunately, is not quick-detachable, tightening is done with a regular screw:

The side handle is removable, not anti-vibration, although at such a low cost of the tool, this is not surprising:

In this case, most of the sparks will fly under your feet during operation. I would like to remind you that it is not recommended to use the grinder with the cover removed and without goggles, and given the sufficiently high power of this model, the side handle will clearly not be superfluous. With all the recommended accessories, the sander looks like this:

Recommended for installation circles with a diameter of no more than 125mm:

Since a collector motor with double insulation (class II) is used in the grinder, there is no need to use grounding, therefore, the plug is used here a conventional cast, designed for 16A:

The length of the mains cable is 2m, which should be enough for most users. Wire marking. H05VV-F, cross-section 2×0.75mm2.

Disassembly and main parts:

I think that it is no secret to anyone that with proper operation and good care of the tool (timely cleaning and lubrication), it will serve for many years. This grinder is no exception. Since when cutting or cleaning metal, dross (sparks) and soot are constantly emitted, it is advisable to clean it periodically. In addition, some work can be carried out in dusty rooms, and since the cooling of the tool is air-flow (air is driven through the entire body), some of this soot / dust is deposited on the walls and various electronic elements. In this model, the intake of cold air occurs from the side of the handle, therefore, it is in this place that the greatest accumulations of dust / dirt will be observed. To access the elements inside the handle, you need to unscrew only four screws:

After that, the handle will open into two halves and the following components will become available:

Now let’s dwell in more detail on the most important components. The FD-26-413A triac regulator, designed for 250V / 12A, is responsible for adjusting the spindle speed (it has a cooling radiator on the reverse side):

The regulator is quite simple, it does not maintain the set power (does not have feedback). The power button is rated for 250V / 6A:

Its stroke is quite soft, and thanks to the presence of a latch, it makes work much easier. These are the most vulnerable components, so for trouble-free operation, I recommend cleaning them occasionally or simply vacuuming them.

Let’s go further. By unscrewing 4 screws from the end of the body, you can disconnect the rotary gear, which is responsible for transmitting torque from the rotor (armature) to the spindle at an angle of 90 °:

There are no complaints about the quality of workmanship: the lubricant is present in sufficient quantity, there are no beats, the body is made of a durable magnesium alloy. I would like to note an important feature of the gearbox, namely the use of a hypoid gear transmission instead of a spur gear:

This allows you to reduce the noise during the operation of the tool, because gear engagement is smoother. In addition, due to the increased clutch area (compared to spur gear), hypoid gears can handle much higher maximum torque without damage.

Larger view of the hypoid gear on the motor shaft:

We smoothly move on to the very “heart” of the grinder. the rotor (anchor) of the electric motor. Here we will dwell in a little more detail, since this is the most vulnerable part in any power tool. It is from its quality of manufacture, first of all, that the service life of the tool as a whole depends. In our case, everything is just fine: there are traces of rotor balancing, armor protection of the winding and a deflected collector. I suggest you take a look and see for yourself:

I wrote about the advantages of having a balancing in previous reviews about the power tool. I will only say that this is some guarantee that the bearing units will last longer and there will be no beats of all kinds that will gradually disable the rest of the parts. The balancing here is somewhat “barbaric”. some upper part of the plates is simply milled out. The downside is that in this place the plates turned out to be, as it were, short-circuited, although, according to the idea, each plate is isolated from the neighboring one by applying varnish or a special thin micanite gasket to it, or scale. This makes it possible to achieve a reduction in eddy current losses. In any case, thanks for the fact that balancing is present, because without it, the service life of this tool would be much shorter.

If you look more closely at the manifold assembly, you will notice that the manifold is bent, i.e. removed mikanite insulation between the lamellas to a depth of 1 mm, and the junction of the windings is filled with a compound:

For additional protection of the winding, a bandage in the form of a non-magnetic wire and lacquer filling both from the side of the collector and from the side of the gearbox are used. This is done so that the centrifugal force does not fluff the winding (after all, 11000 rpm), as well as to protect against various particles, since even the impact of a small dense crumb on a winding rotating at a breakneck speed can easily strip the insulation from the wire.

It is also important to use in this model closed bearings (marking 607V) and a protective lining that prevents the ingress of various dust / dirt into the bearing assembly:

The service life of such bearings is much higher than similar ones, but without the protection of the balls, and given the “dusty” scope of the tool, this is a very big plus.

Next, we turn to the stator of the electric motor. Its winding is covered with a plastic cap in case of protection from the fan blades, as well as to create the necessary air flow (it is close to the “fan”):

There are no complaints about the quality of the stator: the winding is fixed, for additional insulation there is a layer of varnished cloth and an additional layer of plastic insulation (double insulation):

If you look closely, you can see stiffening ribs along the inner perimeter of the case, designed to increase the mechanical strength, as well as to cool the entire tool. In addition, the body itself is made of impact-resistant plastic, so it easily withstands a careless attitude. As mentioned earlier, air intake occurs from the manifold side and passes through the entire engine (through the stiffeners), thereby cooling it. Outlets are located on virtually all sides at the front of the chassis.

A little trick for quickly cooling the electric motor of the tool, which many do not know about. just run it idle at maximum speed for a couple of minutes. A similar “fan” will blow through the windings and thereby cool the motor to an acceptable level. This will significantly extend the life of any tool.

The bearing seat is molded with rubberized inserts (bushings), so you can forget about any shifts or beats. Access to the brush-collector assembly is simple, there is no need to disassemble the entire tool (for more information on replacing brushes, see “Service”):

That’s all for disassembly, the assembly is done in reverse order. If there is a need to turn the gearbox, then thanks to the successful design, this will not be difficult. To do this, unscrew 4 screws and turn the gearbox to the required angle (90 ° / 180 ° / 270 °). In the photo below, an example of turning the gearbox by 90 °:

In total, there are practically no complaints about the quality of workmanship, everything is assembled fairly well with a good margin. At first, I doubted the declared power of the electric motor, since, judging by the dimensions of the stator / rotor, we have an honest electric motor with a capacity of 800-850W. So I decided to check the power consumption with a wattmeter. Since the electric motor is a pronounced reactive load, the readings of the wattmeter can be a little twisted. In the video below, the angle grinder Caliber МШУ-125 / 955E with a “good” load consumed more than 1kW:

It should be noted that I conducted the tests in a country house with very mediocre electrical wiring. In the video, you can see how the voltage sags under load (sank to 210V), so with high-quality wiring, this grinder will consume more than 1.1kW. Be that as it may, to work with 125mm circles this power is enough for the eyes.

Tool maintenance:

I already mentioned earlier that it is necessary to periodically disassemble the tool and clean the main components from dirt / dust. It is also necessary to monitor the condition of the brushes and, if necessary, replace them. For this, a pair of spare brushes are supplied in the kit. Thanks to the successful design of the grinder, this operation will take very little time. no need to disassemble the entire case. It is enough just to unscrew the plastic clamping screws:

And finally, a couple of recommendations for work:

A small demonstration of how it works:

Pros:
good workmanship
compactness
high power
availability of a speed regulator
hypoid gear in the gearbox
Safety class II (double insulation)
adjustable angle grinder (direction of rotation, gearbox rotation)
quick access to brushes
price

Minuses:
– there is no function of maintaining the specified revolutions depending on the pressure on the tool

Conclusion: the tool is really high quality, there are no complaints about the work. Due to the sufficiently high engine power and the presence of a speed governor, this model allows you to solve most of the tasks. I definitely recommend buying.

Angle grinder motor power

The more engine power, the more force the tool develops, the more dense materials it is able to cut. With increasing power, the weight of the device increases. The industry produces tools with motors from 0.5 to 3 kW. For home and summer cottages, it is recommended to choose an angle grinder with an engine power of 0.8 to 1.2 kW. The more powerful mechanism is more difficult to hold in the hand, it consumes more electricity during operation.

A professional tool is designed for long-term operation, it has a higher service life. If large-scale construction is planned in the country, cutting steel bars, assembling formwork. you can use a tool with a motor up to 1.5 kW.

Additional features

Additional features offered by the manufacturer will make working with an angle grinder convenient and safe:

• Smooth engine start. A very useful function. the disc spins up to working speed gently, without “explosive” jerk at the start.
• Automatic disk balancing. Reduces vibration of the instrument in the hands. Particularly helpful when using an unevenly worn disc.
• Number of handles. For household angle grinders, as a rule, there are two threaded holes and one handle that can be rearranged. This is very convenient if you need to change your hand while working in order to get into a narrow place.
• Rotation speed regulation. The electronic circuit maintains a constant speed of rotation of the motor shaft, regardless of the load on the disc. Work goes faster, the motor and gearbox will last longer.
• The presence of a dust protection system. An important function for concrete work. the gearbox and shaft are protected from the ingress of cement particles, increasing the service life of the tool.
• Possibility of connecting a construction vacuum cleaner. Along with personal protective equipment. respirator, goggles and gloves. it increases the comfort and safety of work. The workplace will stay clean.
• Locking the start button. For extended operating conditions such as grinding or polishing, the operator does not need to hold down the button in the operating position.
• Auto power off. If the light is turned off during operation, the machine de-energizes the tool so that it does not start itself when the power supply is restored.

What parameters are important when choosing an angle grinder?

Table: technical data of angle grinders with a disc diameter of 125 mm

Understanding the models: how to choose an angle grinder

The minimum mark is located, as already mentioned, at 115 mm. The use of the unit is limited to small household chores. It is forbidden for them to cut even non-dense materials.

End users fall in love with the angle grinder for its low weight and maneuverability. The palm grinder among the demanded angle grinders is held by the model with a disc diameter of 125 mm.

The model has the optimal rotation speed for most finishing and grinding work.

The only significant drawback is not the ability to “bite” into too hard surfaces, but for these cases there are more powerful models:

The weight of the product and the diameter of the disc are two significant indicators that speak about the ability of the angle grinder to cope with the task assigned to it. Low-power models equipped with a 125 mm disc are used exclusively for finishing work. In the event that it is necessary to build a new structure, it is wiser to opt for a 230 mm angle grinder.

Additional functions: all the pros and cons

In some cases, the model differs from competitors by the option of “soft start” or “auto-balancing”. It is not easy for a beginner to figure out what is needed and which option can and should be discarded. To answer this question, it is necessary to consider in detail possible technical innovations.

Soft start options mean a smooth start to work. This is true for those who are not sure of the strength of their own hands.

The second option allows you to reduce the physical load on the disk. A beginner cannot independently determine which part of the working surface has worn out to a greater extent. The “auto-balancing” system will do it for him.

Besides the two options mentioned, there are a number of others:

• Automatic switching off of brushes. its advantage will be appreciated by those who work in conditions of an increased probability of a voltage drop;
• Dust Removal. Expensive angle grinders can independently remove dirt from hard-to-reach places.

Best Angle Grinders in 2020. Top 6 Angle Grinder Picks

The importance of disc size: how to choose an angle grinder for your home

The degree of intensity and the purpose of use are the criteria from which you need to build on. Official suppliers always indicate the diameter of the circle on the surface. The minimum mark is 115 mm and the maximum is 230 mm. The obligatory consideration of these numbers will help to choose the right angle grinder. For example, for work on metal and wood, a disc is required, the diameter of which ranges from 170 to 230 mm. It all depends on the degree of strength of the material.

There is an important caveat when talking about cutting wood and metal surfaces. Even the strongest blade cuts exclusively with the part protruding from the body. For example, the case width is 50 mm. In this case, you can only cut ½ x disc diameter = 25-30 mm.

It is not only the operational dimensions that matter, but also a number of other nuances:

• The unit must be equipped with a protection system against overheating and voltage drops in the network;
• Grinding work at home is done with a 125 mm disc;
• It is better to cut pipes using an angle grinder (angle grinder) equipped with a disc with a diameter of at least 180 mm.

The existing needs will help you decide which angle grinder you need to choose for your home and summer cottage. Similar gadgets are used for grinding and less often for cutting. If exactly the second is needed, then the final choice is due to the type and thickness of the material.

Power characteristics: how to choose the right angle grinder

The lower bar is at 0.5 kW, and the upper one is 2.5 kW. There are two common misconceptions that need to be dispelled when talking about power. First, there is no relationship between the diameter of the working surface and the power. The second ingrained stereotype says that a high-quality, angle grinder can only be found with maximum power.

Based on the information collected, the optimal power is selected:

• Standard home furnishings are best done using 125 mm / 1.5 kW;
• For those who plan to rebuild pipes in the country or at home, it is recommended to take 150 mm / 2 kW;
• A professional builder should give preference to a model with a 230 mm circle and a power of at least 2 kW.

Don’t put the most powerful option in your shopping cart right away. Excess power is the cause of most of all waste during the practical operation phase.

Unit rotation speed: which angle grinder is better

It is useful for a beginner to know that even two angle grinders identical in terms of power and diameter of the working surface differ in the speed of its rotation.

When it comes to sanding, a good machine is of the utmost importance. The diametrically opposite is necessary when it comes to cutting.

Continuing this topic, users should focus on the number of pens. The very first angle grinder on the market had only one handle located at the spindle. The small weight and diameter of the disc allowed manufacturers to limit themselves to this option.

Until a certain point, this was quite enough, but as technical development progressed, people began to look for more efficient options in all respects:

• Models available for left and right handers;
• The degree of fastening of the holder depends on the weight of the product and the diameter of the working surface;
• An angle grinder with two handles is best for sanding dense surfaces, otherwise serious injury may occur.

The number of handles on a construction tool depends on the speed of rotation and the diameter of the working surface. The higher the mentioned indicator, the more pens are needed. Otherwise, it is easy to get hurt.

Builders note how to choose an angle grinder: 5 criteria

How to choose an angle grinder

The correct choice of angle grinder depends on understanding the purpose of its use. It analyzes what and how often it is planned to process it. The model with 125 mm disc is only suitable for grinding, and 2 times the diameter is required for cutting. Do not lose sight of the power of the product. The harder the material is processed, the more power is needed.
