Description of angle grinder Metabo WEV 15-125 Quick:

angle grinder Metabo WEV 15-125 Quick. a tool that can change the way you think about angle grinders.
Powerful, high-performance, and at the same time, compact and convenient. Functional and safe, yet highly reliable and durable. Metabo engineers have managed to find a near perfect balance between these characteristics and create perhaps the best angle grinder with speed control.

Features of the Metabo WEV 15-125 Quick angle grinder:

  • The heart of the machine is the latest generation Metabo Marathon engine, which incorporates a number of innovative solutions (patent pending) to significantly increase its efficiency. As a result, the motor delivers up to 50% more torque and 20% better overload resistance.
  • The complete Metabo Vario-Tacho-Constamatic (VTC) speed control electronics are equipped with a constant speed control subsystem under load. Thanks to this solution, the angle grinder can work with a variety of materials, and the work efficiency will always remain at the highest level, regardless of the intensity of the load.
  • Completely redesigned cooling system compared to the previous generation angle grinder. The air intakes are located at the rear of the housing in such a way as to completely exclude them from being closed by hand during operation. Fan with modified blade geometry. more efficiency, less dust remains inside.
  • The Metabo WEV 15-125 Quick model has the highest level of safety in operation thanks to soft start systems, a switch with an accidental and reclosing lock, a convenient system for changing the position of the protective cover and the Metabo S-automatic release clutch (if the disc is jammed in the material, the clutch disengages the drive and stops rotation).
  • Metabo Quick, a keyless disc change system, is now even more convenient to use and allows you to unscrew any disc with two fingers, no matter how it is clamped.
  • Low vibration thanks to a new generation motor, state-of-the-art bearings and excellent tool balance. Metabo Vibra-Tech (MVT) side grip dampens most of the residual vibration, making the tool comfortable to use.
  • Switch with restart protection. In the event of a loss, and then a sudden turn on of electricity, the angle grinder will not turn on spontaneously, but it will be necessary to turn off and back on the tool with the button.
  • Two position side handle and gear housing rotatable in 90 ° increments. You can always choose a comfortable tool position, regardless of the working conditions.
  • Wear-resistant carbon brushes with automatic shutdown functions.

angle grinder with speed control. a tool with the function of setting a certain number of revolutions of the grinding, cutting or polishing wheel to select the optimal rotational speed for a specific material.

When to use the variable speed angle grinder

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 metal cutting, you need to set it from 7000 to 10,000 rpm. Wood is sanded at a 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 attachments will become unusable. But for cutting a bolt 15 mm in diameter, it will take already 8000 rpm.

Parameters for selection of angle grinder with speed control

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

Metabo two-hand angle grinders are equipped with a shock absorption system, which is installed in the rear handle.

No matter which Metabo angle grinder you choose. a compact, lightweight one-handed machine for cutting metal profiles, roughing and sanding, deburring weld seams and trimming tiles, or the heavy Metabo two-hand angle grinder for complex metal work, concrete work, cutting solid materials and sanding hard materials, you can be sure of the high quality, reliability and safety of your tool.

angle grinder Metabo. the best choice of professionals.

Advantages and disadvantages

Angle grinders with speed control are presented on the construction market in a huge range. Depending on the design features and technical characteristics, they can have both pros and cons. So, household models are compact and lightweight, but their functionality is limited. In such devices, productivity is also reduced, during operation they quickly overheat and require constant stops.

As for professional tools, they are very powerful and endowed with additional functions that allow them to be used for a long time without overheating the mechanism. These angle grinders are of excellent quality, easy to operate, and are designed for both cutting and grinding workpieces. The disadvantages of these models are the high price and high weight, since the frame of the device and additional components are made of durable material.

The main advantage of an angle grinder with speed control, regardless of their modification, is the ability to set a certain operating mode. Thanks to this, the device becomes multifunctional and allows processing of various materials.

Models and their characteristics

Today, angle grinders equipped with speed control are in great demand among craftsmen. This type of tool is well suited for cutting, polishing and grinding workpieces. The construction market is represented by an angle grinder made by both domestic and foreign companies. Models from several brands have proven themselves well.

Selection Tips

The variable speed angle grinder is one of the most popular and widely used tools. Since this tool is represented by different modifications, it is difficult to make the right choice in favor of this or that device. The first step is to decide how the device will be used for domestic or professional purposes. In the event that infrequent and simple work is planned, then a small low-speed machine will do. For the simultaneous implementation of high-quality cutting and grinding of the material, it is best to opt for professional models.

In addition, it is worth paying attention to the following characteristics of the device:

  • performance:
  • minimum and maximum number of revolutions;
  • additional functions;
  • disk parameters that can be used with the instrument.

An important criterion when choosing is the frequency of operation of the device. For constant and intensive work, it is necessary to buy models in which the outer case is made of durable metal and supplemented with brass inserts. When installing the pipeline, it is advisable to use devices with the maximum level of protection against water and dirt.

Features of the

The variable speed angle grinder is a versatile and multifunctional tool that makes it easy to tackle any task in construction and renovation. The main difference between such an angle grinder is the ability to independently set the speed of rotation of the disk, depending on the type of material being processed. Manufacturers produce a device with an electric motor, the power of which can range from 500 to 1500 watts. For cutting blanks, you can choose machines with an average performance of 800 W, but if you plan to carry out grinding, then it is recommended to give preference to more powerful models, since the area of ​​contact with the surface of the processed material is larger in this case.

The angle grinder with speed control is an absolutely safe device to use, since all models are equipped with a full range of protective systems that exclude injury. Let’s list the main.

  • Soft start device. It is responsible for the smooth operation of the tool after pressing the start button. This device can also act as an inrush current limiter, which extends the life of the device.
  • Safety clutch. In the event that, when processing material, the disc of an angle grinder begins to “bite” or wedge, this device starts an emergency stop.
  • Emergency brake. When machining hard material, the tool can twist and pull out of the hand. The brake helps to stop the rotation of the disc in 3 seconds.
  • Coil impregnation with a special compound. Since the cutting and grinding of the material is accompanied by the appearance of abrasive dust, its penetration into the device is prevented by additional processing of the coil with a protective layer. This avoids short circuit problems.
  • Heat dissipating slots. Protect the device from overheating during intensive work.
  • Balancing system. The circles of the machine may be ground unevenly, after which trembling and beating of the machine may occur during the processing of workpieces. Special automatic balancing helps to smooth the work.
  • Overload fuse. When the cutting part heats up to a temperature above 160 degrees, the automatic system is triggered, and the rotation speed of the disc first decreases to 200 rpm, then stops completely.

angle grinders with speed control weigh from 2 to 5 kg, their performance depends on the diameter of the disc and the number of revolutions. Mini models are very popular with craftsmen, which are suitable for working with 115 and 125 mm wheels. Their speed ranges from 10,000 to 11,000 rpm. The 115mm disc angle grinder is generally used for cutting material up to 28mm thick and is well suited for sanding wood, tile, porcelain and glass. Devices with 125 mm discs are considered the most popular, as they perfectly cope with grinding the surface of any material and cutting parts with a thickness of 30 mm. If it is necessary to cut and grind steel pipes, bricks and concrete, then it is recommended to use a device with a circle of 150 mm, while metal processing should be carried out at high speeds, and stone. at lower.

The attachment of the cutting disc to an angle grinder with speed control is carried out using a spindle stop and a protective key, in some models there is also a self-clamping system. Additionally, manufacturers also equip the tool with a casing that protects the craftsman from dust, sparks in the eyes and breaking the circle on the go.

Every master has at hand such a reliable tool as an angle grinder. With the help of this device, you can not only perform high-quality cutting of material, surface grinding, but also sharpen kitchen knives. Since certain types of work require minimal disc rotation, it is recommended to purchase a device with a speed control.

What is the adjustment for??

The quality of cutting and grinding of the material directly depends on the set speed of rotation in the angle grinder. Since hard and thick workpieces lend themselves well to cutting at maximum speed, and aluminum, on the contrary, can melt when heated, then when working with them, the speed of rotation of the disk should be adjusted. Control of operating modes is provided only in models equipped with a special controller. This function is useful and used in several cases.

  • When processing stone. This material is well cut and grinded at low speeds; for each type of stone, its own disc speed is selected separately.
  • For finishing delicate surfaces that require careful handling. At high speeds, such products can deteriorate.
  • When replacing one circle size with another. In this case, a speed correction is needed.
  • When using in the work of crowns and discs with diamond dusting. To avoid their overheating and breakage, workpieces must be processed at low speeds.

If the tool is only planned to carry out threaded operations, then there is no need for a speed controller. When used universally, the angle grinder is irreplaceable. The speed control system in the angle grinder is represented by integrated microcircuits. They are reliable in use, function with a soft starter and a tuned module.

How to use?

Despite the fact that all models of the variable speed angle grinder serve flawlessly, they still require proper care and operation. Therefore, it is periodically necessary to replace the working attachments and contact brushes, add oil to the gearbox and clean the engine compartment from dirt. In addition, a technical check of the instrument is also provided; it should be carried out at least once a month.

When replacing the discs, the device must be turned off, the gearbox must be locked with the button, then the old nozzle must be removed and a new one must be installed, pressing it tightly with a nut. Filling with oil is simple: to do this, remove the gearbox cover, having previously unscrewed the mounting bolts. As for cleaning the case from dust, it is carried out using a vacuum cleaner.

Work with an angle grinder must be carried out in accordance with all safety regulations. The technician must wear protective gloves, goggles or a face shield. Do not start cutting with a broken or cracked blade as it could cause injury. Grinding with a cut-off wheel is also not allowed, and cutting with a stripping.

For cutting and polishing various materials, a certain speed of rotation of the disc is required, it can be adjusted using a special automatic system, which is controlled on the body by moving a lever. Thus, the revs can be easily decreased or increased. In addition, you can reduce the speed using large diameter discs.
