Lever 125 with speed control and soft start: TOP 10 best

Most home craftsmen always have a tool at hand that helps them cut a piece of metal of the required size, sand the surface, or even sharpen a kitchen knife. This is an angle grinder. Its disk rotates at high speed, which ensures efficient performance of work. But not every operation requires maximum speed. Then a grinder with speed control will come in handy, which will ensure quality and safety.

Why is this option needed?

Angle grinders with a regulator have much greater versatility and functionality.
The ability to independently set the rotation speed for a particular type of material allows you to use the device for a wider range of jobs. The adjustment range of different types of angle grinders varies. The linear speed of the peripheral part of the disk increases directly with increasing radius. However, it is limited to about 80 m/s (at higher speeds the disk may collapse). Therefore, grinders with small diameters (115 mm, 125 mm) have high speeds (about 12,000 rpm). Low-power (up to 1200 W) household grinders have this size. Therefore, the device for changing the rotation speed of such angle grinders has the largest range of regulation. However, these devices are not suitable for intensive work. You should take breaks after 5-7 minutes of work so as not to overheat the grinder engine.

For size 150 mm. the rotation range adjustment is reduced to 2300–9000. And when using a circle 180 mm. the maximum speed will not exceed 8 thousand revolutions. For larger diameter discs, the rotation speed will be even lower. These wheel sizes are used in professional tools that can be used for up to 6 hours of continuous use. The power of these devices can reach 3 kW.

Angle grinder (grinder) MAKITA GA4540C with speed control, disc diameter – 115 mm.

Depending on the specifics of the work performed, the following values ​​of the number of revolutions per minute are usually used:

• 2000–3000 – metal grinding;
• 2000–4000 – wood processing;
• 5000–7000 – stone cutting;
• 7000–10000 – metal cutting.

The presence of speed control on an angle grinder automatically places this device in the section of universal devices designed for different types of work. With the help of such grinders you can cut, grind, sharpen, polish various types of materials:

• concrete;
• granite;
• stone;
• metal;
• tree;
• brick;
• plastic.

Therefore, when using this tool professionally, there is no need to use other devices if the surface being processed or the thickness of the workpiece changes. This saves time and money. There is no need to have a set of different angle grinders for each specific case. All you have to do is move the disk and change the speed.

Makita 9565CV angle grinder with speed control

The number of revolutions is usually adjusted when performing the following tasks:

• When cutting metal of different thicknesses, different rotation speeds are used. The thinner the material, the slower the disk should spin. Otherwise, the cutting will not be performed efficiently: when rotating quickly, the disk may move to the side and the cutting path will be uneven. When working with thicker metal thicknesses, there is no cut deformation and it is possible to use modes with high rotation speeds of angle grinder disks.
• Cutting one type of stone at high speed can cause gouges and unevenness at the cut site. At the same time, to process another type of rock, it is necessary to use high speeds. Therefore, the rotation mode is selected individually for each case.
• Grinding and polishing initially imply the ability to regulate speed. An incorrectly selected speed limit can cause damage to the surface being treated, for example, when polishing a car body.
• The surface of diamond wheels quickly becomes damaged when overheated. Therefore, when using them, the rotation speed should be reduced.

Important! When performing various types of work, always select the diameter of the disk and its rotation speed individually for each specific task.

Of course, if you are constantly engaged in the same type of activity, for example, cutting corners with rods or polishing a surface, then you probably shouldn’t bother buying an angle grinder with adjustment. After all, such machines are much more expensive than regular ones.

On the other hand, when changing or expanding the scope of work, additional functionality may be needed. And the savings that were justified earlier are transformed into today’s costs in the form of the purchase of additional equipment.

Other useful features

In addition to speed control, such devices are equipped with additional options that make their operation convenient and safe.

Smooth launch. One of these features is soft start. During the start of operation, the starting current reaches a multiple of the rated current. Such high values ​​have a detrimental effect, primarily on the durability of the motor windings. In addition, large angle grinders with inertial mass can break out of the operator’s hands when starting, which increases the risk of injury.

Angle grinder (grinder) MAKITA GA6040C with speed control and soft start

To avoid this situation, use the soft start option. Its mechanism is an electronic unit that is built inside the angle grinder and is designed to limit the starting current. Thanks to this option, it is possible to avoid the above-mentioned negative consequences and increase the service life of the tool.

Attention! When working with an angle grinder, you must follow safety precautions. Otherwise there is a risk of injury.

Accidental start protection is another feature designed to ensure operator safety. To start the grinder, you need to press two buttons. One, as a rule, is made in the form of a trigger at the bottom of the handle. The other one is on the side. Starting is only possible by pressing the buttons simultaneously.

Option for quick disc change (M-Quick). This function is necessary if you have to frequently rearrange the circles. With its help, after pressing the button, you can unscrew the nut securing the disk without using a key. The first developers of M-Quick were Metabo specialists. Later other manufacturers began to use it.

Jam protection. During operation, cases of disc biting often occur. There may be several reasons for this:

• the nut pressing the disk is not tightened;
• processing of hard material with a dull tool;
• there may be solid foreign bodies inside the processed body;
• The grinder's working tool is incorrectly positioned relative to the object being processed;
• the installed disk does not correspond to the parameters (diameter, thickness, material, etc.) of the technical characteristics of the angle grinder.

Angle grinder (grinder) METABO WEVA 15-150 Quick with speed control and quick disc change option
In such a situation, the grinder can break out of the worker’s hands and cause injury. There are often cases when the abrasive breaks and scatters into pieces, which also leads to sad consequences. To protect the worker in these cases, manufacturers have begun to install an anti-jam system. It comes in two types:

• mechanical;
• electronic.

The operating principle of the first type is based on the use of a special coupling, which, in the event of jamming or overload, begins to slip and does not transmit torque to the nozzle. In the second type, a special electronic unit is responsible for this. It reads the electrical parameters of the angle grinder. When a disk jams, the current increases sharply, which is detected by sensors and transmits information to the unit, which, in turn, gives the command to turn off the power to the device.

Reference! In order to protect the operator in case of abrasive breakage, protective covers are used.

Automatic disk balancing. Auto-balancing is necessary when working with circles of increased diameter (from 180 mm and above). During operation, the abrasive wears unevenly. As a result, the center of mass shifts from the axis of rotation of the working tool, which causes vibration. This is especially noticeable on large disks. It can be difficult to make an accurate cut with such a tool. And here you can’t do without automatic balancing.

Load stabilizer. When the density of the material being processed changes, the rotation speed changes. The stabilization function will help maintain the specified number of disk revolutions. This option is useful when cutting natural materials: granite, marble, stone.

Continuous operation mode. For long-term non-stop use of the tool, manufacturers place a special button on it for continuous use. Having pressed and fixed it once, you can continue to work without pressing anything else. This is very convenient when doing long grinding or cutting tasks. The grinder will rotate the circle until the operator turns it off.

Why do you need a soft start and speed control on an angle grinder?

On drills and screwdrivers with similar capabilities, the rotation control mechanism has a trigger design. The operating features of grinders do not allow the use of such devices, since the shape of the tool implies a full palm grip. In addition, safety requirements prohibit changing the set rotation speed of the disk of a running angle grinder.

A smooth start-up and drive rotation control circuit can only be implemented in devices using commutator-type electric motors.

Angler grinders with the function of speed control and gradual start are highly reliable due to the reduced load on the electrical elements and the mechanical part of the tool.

In conventional angle grinders, at the moment of starting, excess voltage is applied to the rotor and stator, sharply increasing the starting current on the coils. This has a negative effect on conductive elements. Despite the fact that manufacturers provide for operation in this mode, voltage drops in the home network sooner or later lead to an interturn short circuit.

A sharp transition from a state of rest to increased speed greatly wears out the gearbox, forcing it to operate in overload mode. Anyone who has ever used an angle grinder knows the feeling when it breaks out of your hands the moment you turn it on.

Using an angle grinder with a soft start allows you to avoid voltage dips in the network. This means that switched on household appliances will not be at risk of burning out.

Let's consider the practical benefits of the speed control function:

1. It becomes possible to qualitatively cut thin-sheet products from tin or soft materials. Operation at high speeds will lead to melting of the edges of the product due to exposure to temperature.
2. Some ceramics are cut at low speeds. Otherwise, small particles may break off on site, which will spoil the appearance of the workpiece and may cause injury.
3. Grinding of different materials is carried out at different speeds. The adjustment mechanism will help you choose the optimal operating mode without the risk of damaging the surface. This is especially important when polishing products with low melting points.
4. The spindle speed depends on the consumables used. For example, diamond discs are operated at reduced speeds to avoid overheating of the contact surface.

It weighs a little less than two kilograms and, compared to others, seems like fluff. Like other sanders of this class, it will take wood, ceramics and metal. The main thing is to choose a disk. Among the advantages, we highlight the spindle lock for high-speed changing of equipment, a comfortable grip and a casing to protect the operator. However, it is still better to wear glasses. By the way, unlike the previous participant in our best rating, here the casing is adjustable without a key. There are several ventilation holes on the case, through which heat is dissipated. Judging by the reviews, the thing is necessary, but not completely improved, because there are many complaints about overheating during prolonged work. The declared power of 900 W is a decent indicator.

For some reason, angle grinder manufacturers fell in love with the sea green color, so our rating again includes a device in this range. This time from another German tool manufacturer. The sample has all the qualities of a good grinder: quick change of discs due to the locking mechanism, an additional handle, which can also be located on the left and right. By the way, you can insert a marking tool into it, the so-called scriber. You'll have to buy it separately though. You can lock the power button so you don't have to hold your finger on it. The mechanism includes integrated units that are responsible for a smooth start - an important nuance for angle grinders, which was not previously presented in the mentioned samples. The electronic components of this device are generally praised: in case of abnormal operating situations, it will simply turn off and then calmly resume operation. The RPM is adjustable to suit different materials. The casing rotates with the wave of your fingers, without the need to use a screwdriver.

How to work correctly?

When working with an angle grinder, you must follow safety precautions, as this tool is quite dangerous. The basic rules for using a sander are:

• hold the tool tightly so that it does not fall out of your hands or bounce off the material being processed;
• install only those grinding wheels whose diameter the angle grinder is designed for;
• make sure that the network cable does not get caught under the rotating disk;
• stand as steadily as possible on your feet to avoid loss of balance;
• turn on the grinder only if the user is completely ready for work;
• replace attachments only with the angle grinder turned off and unplugged from the socket;
• be sure to turn off the unit after performing a particular job, do not move around the room or room with the tool turned on;
• after turning off the grinder, turn on the lock for accidentally pressing the “start” button, if the model provides such a function.

Selection criteria 125 usm

The main parameters are the speed of rotation of the circle, the power of the electric motor, decent ergonomics, the presence of basic and additional functions and devices. The price of the car crowns all the possibilities.

Affordable price

A low price is not an indicator of low quality, as the ratings of grinders say. For a fairly low cost, you can choose an angle grinder model that will have:

• good equipment;
• rotation speed controller;
• spindle locking device;
• Possibility of mounting an additional handle and a protective shield in different positions.

It all depends on the required characteristics and planned working conditions.

A review of proposals shows a wide range of “price – quality – parameters” relationships. Less expensive brands are Zubr, Hammer or Military, and Makita even has a slightly higher price, but the quality will be excellent.

Power

The power and speed of rotation of the wheel are directly related, so you should not set the diameter of the wheel larger than specified. It is for it (most often - from 125 to 230 mm) that the structure is drawn up and manufacturing materials are selected.

The specific speed required for a specific task or material is the basis for selecting power. For most tasks, an angle grinder with a power in the range of 0.5-3.0 kW will be sufficient.

The type of circle is important here. If abrasive wheels are used for cutting, not very much power is needed. For grinding wheels with a larger contact patch or larger diameter, increased power is required.

Speed

The rotation speed of the working body, measured in revolutions per minute, is the main parameter for selecting an angle grinder. The ability to regulate speed makes the device universal - it becomes possible to grind, cut, sharpen and even polish with one tool.

The typical speed gradation depending on the operations performed is as follows:

• up to 3000 – surface grinding;
• 3 – 4 thousand – work with wood;
• 4 – 5 thousand – work with metal, without cutting;
• 5 – 7 thousand – cutting stone and concrete;
• 7 – 10 thousand – metal cutting.

When a grinder with speed control comes in handy

The main purpose is the processing of various materials. You need to grind metal at 2000 - 3000 rpm, cut stone at about 6000 rpm, for cutting metal you need to set it from 7000 to 10,000 rpm. Wood sanding is performed at minimum speed - from 2000 to 4000, depending on its density. If you try to work with wood at 6000 rpm, the part will turn black and the bits will become unusable. But to cut a bolt 15 mm in diameter you will need 8000 rpm.

The best angle grinders with a disc diameter of 230 mm

For cutting depths of up to 70 mm, angle grinders with a disk diameter of 230 mm are used. These heavy models are rarely used at home; the scope of application is cutting thick-walled metal and metal products, paving slabs, curb stones, and concrete processing. To perform these tasks, the power has been increased, there are systems for protecting the tool from overloads, a smooth running mode, and adjustment of the number of revolutions.

Makita 9069

The Makita 9069 angle grinder has a power of 2000 W, a maximum speed of 6600. The weight of the model is 4.2 kg, with dimensions of 528 * 189 * 177 mm. This is a simple and reliable angle grinder with a minimal set of functions. There is a locking start switch and multi-stage protection against dust getting inside.

+ Pros of Makita 9069

1. Comfortable grip, hands do not slip.
2. There are three holes for attaching a second handle.
3. Armature and winding armoring.
4. Elastic power cord does not interfere with operation.
5. The power is enough to cut thick-walled metal and stone.

— Cons of Makita 9069

1. There is no smooth start, you need to hold the tool tightly.
2. There is no jam protection.
3. Heating occurs at the point where the brushes come into contact with the body.
4. The plastic of the case has an unpleasant odor, which dissipates over time.

Conclusion. This sander is designed for professionals. It is used for all types of work, but when cutting metal you need to monitor the load. The tool is not suitable for sanding wooden workpieces.

Metabo WEV 10-125 Quick. This is already the second grinder from this manufacturer in the rating. Only now for 125 mm disc. The angle grinder also has a safety clutch and replaceable brushes that turn off when there is a voltage drop in the electrical network. In addition, the manufacturer has supplemented the tool with an overheating indicator, a stabilizer and a long cable.

Interskol UShM-125/1100E. An inexpensive domestic grinder with speed adjustment from 3000 to 12000 and a disc size of 125 mm. One of the few tools with the ability to change the rotation speed from this company. She has proven herself well as a home assistant.

BISON USHM-125-1100 TM3. Another worthy Russian device with soft start. The model has an ergonomic body and is simple and easy to operate. The additional handle that comes with the kit can be fixed in two positions, which makes its operation even more convenient. In addition to adjusting the disk speed, the device is equipped with a button that blocks accidental activation, as well as overload protection.

It is worth noting that speed control is usually used in angle grinders, where the use of a disk of small diameter is provided: 115, 125, less often 150 mm. In angle grinders with wheel sizes of 180 and 230 mm. This function is practically never found. This is due to the fact that as the radius increases, the maximum speed in the device is lower. So, with a diameter of 115 mm. rotation speed can reach 12,000 rpm. And with a size of 230 mm. - only 6000, in rare cases 8000.

Parameters for selecting an angle grinder with speed control

• The rotation adjustment range primarily depends on the maximum diameter of the nozzle. The smaller the disk, the faster it rotates. For 115 and 125 mm angle grinders with speed control, this parameter ranges from 2800 to 10,000 – 12,000 rpm. An angle grinder with a 150 mm disc has a narrow range from 2300 to 9000 rpm. For most angle grinders with a 180 mm disc, you can change the number of revolutions from 3000 to 8000 rpm.
• Power - household angle grinders with speed control of no more than 1200 W can work with 115 - 125 mm discs. Perfect for work that takes no more than 30 - 40 minutes a day: cutting parts made of metal, wood, plastic up to about 50 - 60 mm thick, depending on the diameter of the body of the grinder itself. Professional models are most often used with large diameter disks (150, 180, 200 mm) and operate for 4–6 hours without interruption with high power of 2000–3000 W. By the way, the price for such a tool is an order of magnitude higher than for household ones.
• The soft start system will increase work safety, especially if the maximum speed is set, and will allow you to start work carefully. The constant speed function is important when processing hard materials so that productivity does not drop when the blade collides with the material.

Tool types

Typically, devices used at home are characterized by small sizes and increased requirements for working conditions. Their technical capabilities do not go beyond household operations. As a rule, after 15-20 minutes the technician’s hands will feel an increase in the heating of the device body. This means that you need to take a break from work. Intensive work every day is beyond the capabilities of such an angle grinder.

For industrial use, you need a high-performance, reliable angle grinder with soft start and speed control, with a moisture- and dust-proof housing for manipulation in adverse environments. Typically, such devices are difficult to break , so it is perfect for daily full-time work. When performing operations with such a device, you do not choose the type of material, even if it requires delicate processing. All you have to do is reduce the rotation speed of the disk and any tool will do the job.

Such units can also be used at home, for example, during the construction of suburban housing or major renovations. He will show himself only from the best side.

Tips for choosing

The main thing is to determine the purposes and materials for which an angle grinder with speed control is purchased. The key is to perform various operations on an ongoing basis, because stable metal cutting does not require this function, and payment will require additional money. If the mode and materials are often changed, it is optimal to choose a universal model.

For field work, it is better to choose a small machine.

The main recommendations for selection can be listed as follows:

• diameter of the circle: part to be cut - no more than ¼ of the diameter of the circle, necessarily no more than allowed by the design of the angle grinder, but in accordance with the muscular strength of the master (working with a 230 mm wheel for an entire shift can be very tiring);
• protective casing: the possibility of installation in different positions and installation without a key will greatly increase the speed of work;
• mains or battery power: depends on mobility requirements or workshop equipment;
• preparation of the body for holding: rubberized surfaces for the hands, grooves for the fingers, notches on the buttons, anti-vibration materials for the additional and main handles.

The proximity of an authorized service center for repair work under warranty is also important. The faster the response and repair, the less you will have to make do with who knows what. Therefore, if you have to travel 300 km to replace brushes or perform a routine inspection, it is better to choose another brand.

Adjusting the disk rotation speed

The quality of the work performed is often determined by the set speed of the tool, if the design allows it. Thick, hard materials are easier to cut at maximum speed. An aluminum billet, on the contrary, will melt when heated. Therefore, there are operating modes that require the use of an angle grinder with speed control:

• Reduced speed is required for stone work. Each variety has its own.
• Sanding and finishing at high speeds can damage the product.
• When changing a wheel from one size to another, speed adjustments are required.
• Diamond-coated discs and bits are used at low speeds to avoid breakage due to overheating.

If the device is used exclusively for cutting operations, a speed controller is not necessary, but as a tool for universal use, it is simply necessary.
