Grinding machines "Bulgarians": what are they, why are they needed and how to choose yours

Grinders, which we all call "grinders", are one of those tools without which it is difficult to imagine repair, construction or even a home workshop. They appeared in the middle of the last century, when Bulgarian engineers invented this convenient device, and later it became an indispensable assistant for craftsmen all over the world. A grinder is not just a piece of metal with a motor, it is a universal tool that cuts, grinds, cleans and even polishes. In this article, we will understand what they are, where they are used, why they are so useful and how to choose the one that is right for you.

What are Bulgarians like?

Grinders are divided into several types, and each has its own "specialization". By the size of the disk, they can be conditionally divided into small (115-125 mm), medium (150-180 mm) and large (230 mm). Small ones are light and maneuverable models, ideal for precise work or cutting thin materials. Medium ones are the golden mean for most tasks, and large ones are "heavy artillery" for thick metal or concrete.

By type of power supply, there are mains and battery-powered. Mains - for those who work for a long time and do not want to think about charging, but will have to pull the cord. Battery-powered - for freedom of movement, especially on the street or where outlets are far away. There are also professional and household models: the former can withstand many hours of work and are more expensive, and the latter - for one-time tasks at home.

Where and for what are they used?

A grinder is like the Swiss Army knife of the tool world. In construction, it cuts reinforcement, tiles, or bricks, and cleans seams after welding. In the garage, it can be used to cut off a rusty bolt or sand a car body before painting. At home, it can be used to file a metal pipe, sharpen a shovel, or even cut an old lock. And if you put a special disc on it, it can also handle wood or plastic. In short, wherever there is metal, stone, or something that needs to be put in order, the grinder is there to help.

What is their benefit?

The benefits of a grinder are obvious: it saves time and effort. Instead of spending hours sawing with a hacksaw or sanding by hand, you can cut out the necessary part or make the surface smooth in minutes. It is universal - one tool covers a bunch of tasks, from cutting to polishing. In addition, with the right disc, it works cleanly and accurately, which is important for a neat result. For craftsmen, it is also a way to earn money faster, and for home craftsmen - a chance to do everything with your own hands without unnecessary expenses for a workshop.

What problems do they solve?

A grinder is your lifesaver in situations when something needs to be cut or repaired urgently. Rust has eaten away at a bolt? It will cut it. Need to quickly prepare a surface for painting? It will clean it in a couple of minutes. A stone slab does not fit the right size? A grinder will adjust it to your needs. It is irreplaceable when deadlines are pressing or when there is no time to mess around with hand tools. And it is also economical - you do not need to buy a bunch of different devices, because a grinder takes care of everything.

How to choose a grinder? Tips from a practitioner

Choosing a grinder is like choosing a pair of work boots: they need to be comfortable and fit your foot. Here are some tips I’ve picked up over the years of working with them:

1. Define the task. If you are going to cut thin metal or grind small items, take a 125 mm disc, it will be enough. For concrete or thick steel, you need a diameter of 230 mm.
2. Power supply. If you work in a workshop with an outlet – get a mains one, it is more powerful. If you are often away – a battery-powered one will give you freedom, but make sure the battery holds a charge for at least a couple of hours.
3. Convenience. Hold it in your hands before buying – a heavy grinder will quickly tire you. It’s good if it has rubber pads and speed adjustment.
4. Safety: Look for a model with protection against accidental activation and a sturdy casing - this will save you from trouble if the disc jams.
5. Budget. Don't chase the most expensive one - an average model for a reasonable price will suffice for your home. But it's better to avoid a downright "noname" so as not to have to replace it in a month.

Why is a grinder a must-have?

A grinder is not just a tool, it is your work partner. It takes on the most difficult tasks, leaving you time for coffee or rest. With it, you do not depend on craftsmen and can do everything yourself - from repairs to creative projects. The main thing is to choose the one that suits your tasks, and it will work out every penny. So if you are looking for a reliable assistant for cutting, grinding or cleaning - a grinder is waiting for you!
