Domestic and professional Bulgarians
The majority of finishing and roofing works are associated with the processing of the metal profile. And if at small volumes one can somehow manage scissors for metal, then on an industrial scale without a Bulgarians in any way. Ushm( angle grinder) has the widest range of applications in industry and at home, and the micro-Bulgarian is used even in medicine.
Conditionally devices can be divided into professional and household, large and small. When choosing a tool, you need to know for what purposes it will be used. Household bulgarkas have less power, more simple functions. It is necessary to give her rest more often, but this tool will attract her with a low price.
Professional, on the contrary, can work continuously for a long time, equipped with additional devices and functions. They are made of better materials, but also the price for them will be, respectively, higher. Large and small Bulgarians differ in power, size, weight and working conditions in which they can be used.
Large and small versions of the Bulgarian
The smallest Bulgarian, as well as the largest, is characterized by such basic indicators: engine power, spindle speed, ergonomics, weight and size. Power is the most important characteristic of this tool. It is recommended to purchase a powerful tool.
It will allow you to use cutting discs with a larger diameter, that is, it can cut to a greater depth, and also will not heat up quickly. Presence of the spindle speed controller will make the work of the Bulgarian safer, because the larger the cutting circle, the smaller the number of revolutions per minute is needed and vice versa.
A mini Bulgarian is really small, about the size of about two to three electric toothbrushes. In the set, usually goes everything you need: different brushes, disks, grinding wheels, etc. The main advantage of it is the ability to almost "jeweler" work. It was for this purpose that it was created. So, you can easily handle small areas, especially when you can not touch anything around.
For basic functions, it differs little from large Bulgarians, except that it is scaled, because all the necessary attachments are there. It is very easy for her to manage, the position of the hand can be changed without much difficulty, due to the small weight of the instrument. It is also easy to change the position of the tool itself in the hand to provide the desired force or angle of impact.
Large Bulgarians should be equipped with a protective casing and an additional handle that can change their location for convenience. Some models have a special gear, which allows you to change the position of the handle, not moving it from place to place. A small Bulgarian can not have such a handle, because it fits comfortably in the hand and does not require much effort at work.
Mini-Bulgarian can be dangerous
It is required to remember and observe the safety rules when working with the USM, since both the big Bulgarian and the Bulgarian small are one of the most traumatic instruments. When working with it you should use safety glasses. The instructions for the Bulgarian indicate the area of its application, the exact diameter and the thickness of the circle to be used.
Each material requires the use of its type of disc, improper selection of a circle can lead to its breakdown and result in an injury to you. Each cutting circle has a limiting speed of rotation, exceeding which will endanger you. Do not use a larger diameter disc, if the Bulgarian is not designed to use them.
If there is a circle in the presence, but it is not known whether it is suitable for the device and the work to be performed, it is better to refrain from using it. Do not remove the protective cover. Always make sure that the bulgarian is disconnected from the mains when replacing the disks.
The electrical wire from the tool must never touch the blade during operation. Proper use of the instrument will extend its service life and will be safe for you.
