Angle grinder with speed control

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.

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.

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 parts made of metal, wood, plastic up to about 50. 60 mm thick, depending on the diameter of the case 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.

There are more and more manufacturers of such equipment in the world. And each brand strives to make its models as convenient and functional as possible for users. Therefore, it is often very difficult to choose a specific model. Consider the best, according to buyers, 125 angle grinder with adjustable speed and smooth start.

Metabo WEV 15-125 Quick

Reliable, functional unit. Its price may confuse the buyer a little. However, it is well worth the money spent. The user will never regret the choice made for a long time of operation.

The model is characterized by high performance due to the incredible engine power of 1550 watts. At the same time, the angle grinder fits perfectly in the hand, since it is small in size. It is easy to operate thanks to a comfortable body and an ergonomic detachable two-position handle.

  • Safe to use.
  • Reliability
  • Good build.
  • Long network cable (4m).
  • High price.
  • Flimsy speed control mechanism.

How to work properly?

When working with an angle grinder, it is imperative to observe safety precautions, since this tool is quite traumatic. The basic rules for using the grinder are:

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

Small one-hand angle grinder 125mm Titan BSUM7125

Most powerful angle grinder.

The thinner the disc, the faster the workpiece is divided into parts and less motor power is required. The lightest but lightest angle grinder is often chosen for cutting. The power of small angle grinders can be 720 watts, like Titan BSUM7125, and large 2000 watts, like Einhell TE-AG 230/2000

The requirements for angle grinders for grinding are very different. 6mm sharpening wheels are heavier and require additional watts to unwind. When peeling, many locksmiths increase the pressure, trying to remove a larger layer from the surface in one pass and crush the engine. It is more difficult for a low-power motor to rotate during pressing and it overheats faster.
When cutting workpieces, friction occurs at the end of the disk (1-3 mm), and when grinding, the angle grinder is tilted and the contact width of the wiper blade is several centimeters.

When choosing a powerful large angle grinder for roughing parts, like Dnipro-M MShK-2700 (2700 watts) or Titan BSUM26230 (2600 watts), the weight requirement fades into the background. Grinding is carried out under the own weight of the tool, and not on the weight, only by controlling the trajectory of the tooling and slightly pressing.
Among the small angle grinders, the leaders in power are: Forte EG 14-125L with 1400 watts, Makita GA5021C with 1450 watts, Svityaz SKSh 15-125 DR with 1500 watts.

Disadvantages of small angle grinder.

The weak side of the mini angle grinder is the shallow depth of entry of the equipment into the material. So the 115mm Sturm AG9511 disc plunges 25-30 mm, and 125mm Energomash angle grinder-90111 30-35 mm.
This size of the resulting slot is sufficient for cutting reinforcement, angle and rolled steel with a small shelf, cutting a groove in the wall for wiring and a water pipe. But when cutting, the outer edge of the abrasive disc wears out intensively, reducing the already shallow depth of immersion with each cut. If the outer diameter of the tooling of a small angle grinder is not enough, then a workpiece, for example a 57 mm pipe, will have to be cut not at one time, lowering the disc vertically, but scrolling around the circumference. Which is inconvenient, since you will have to re-clamp the part in a vice every time.
