Angle grinder is sometimes a very indispensable tool in construction. Abbreviated angle grinder. Back in the seventies of the twentieth century, when tools from Bulgarian manufacturers appeared on the market, angle grinders were called «grinder». Using a grinder, you can at a sufficient and high level cope with a huge front of work of varying degrees of complexity, the main task of which is grinding, cutting, surface cleaning and various processing of many materials (such as stone, wood, metal). The work of this tool is that the energy from the electric motor is transferred to the moving element (cutting disc, brush) creating rotation at high speed. The worker should only skillfully guide the tool when processing materials.
Some tips for choosing a tool
Grinders are divided into professional and household. They differ, as a rule, in price and design. However, as in the case of any construction tool, first of all, it is necessary to determine the tasks and goals of the assigned work.
Household grinders in most cases are notable for their low construction and low cost, but they have less endurance, as they are not intended to overcome decent loads. It is wrong to consider them the worst in comparison with professional angle grinders, because the tool must correspond to the volume and complexity of the work, and it is not at all necessary to buy an expensive machine for homework, after which it will, for the most part, be lying idle. And vice versa, if the planned work will be long, differing in complexity and intensity, it is better to immediately think about acquiring a powerful professional grinder. Most grinders are reliable and made of good materials, they are characterized by durability in operation. When used properly, the tool can withstand heavy loads every day. However, professional equipment is much more expensive than domestic.
What about power?

What about power?
Low-power grinders are used for cutting sheets up to twelve centimeters thick. Medium power angle grinders can handle diameters up to fifteen centimeters, while a high power tool will allow you to work with material up to twenty three centimeters thick. In other words, it is important to determine in advance which tool will best cope with the task that is set for you..
Grinders are of various modifications: for the participation of one hand in the performance of work and for the participation of two. The angle grinders for one hand have an additional adjustable convenient handle or a rotary gear.
Let’s consider drives
They are mainly of two types: cutting discs and grinding discs. Among other things, they differ in the method of fastening, abrasive type, and grain parameters. Well, of course, in diameter.
To determine whether the nozzles correspond to the material being processed, there are markers on the circles. Abbreviation «AND» indicates that the disk is made of corundum, and it can be used when sawing and processing metal billets. Marker «FROM» silicon carbide discs that are best used with stone and concrete structures are labeled. Diamond wheels are different types of processing asphalt, concrete materials and granite.
Last Tips
Buy grinders from trusted and reliable retailers, where tools and accessories pass exhaust control, and the production technology has long been worked out. When making a purchase, use the services of a test inclusion, wait for the maximum speed of the grinder. You should pay attention to turning it on and off, listening to the sounds (they should be clean, without unnecessary knocks) and the smoothness of the speed reduction.
The case must be strong, preferably made of metal (magnesium alloy, titanium). Low-cost housing options are made of plastic or aluminum alloys. A professional tool is characterized by additional conveniences in the form of an adjustable handle (having several working positions) and a protective casing (which does not require an additional tool for its own regulation).
So what to consider when choosing a grinder? First of all, reliability and compliance with the tasks. Then your work using a grinder will be easy, safe and of high quality..
