LBM types and characteristics

Network
A common option for household needs. The budget model, the cost in stores starts from two thousand rubles. A plus is the price of the device and independence from fuel. However, a wire that is pulled from the outlet during operation can create serious problems. The operator must always ensure that he does not fall under the rotating disc.
Rechargeable
A great alternative to mains appliances. Due to the charged battery, the grinder can work anywhere. They do not depend on the availability of a power source.
A significant disadvantage is the low power of angle grinders. Manufacturers do this on purpose so that the device is economical to consume battery power. A replaceable battery is required for continuous operation. It will charge while the second is attached to the grinder.

Types of grinders by disc diameter
The size of the saw head determines the depth of its immersion in the material. Manufacturers produce devices of different capacities that fit circles of a certain diameter.
- 115 mm. Designed for small grinding jobs and harsh thin materials (slate, thin-walled metal pipes, galvanizing, etc.).
- 125 mm. A common option for household needs. It is used for cutting pipes, tiles, slate, galvanizing, polishing and surface cleaning.
- 150 mm. Suitable for cutting stone, steel or concrete products.
- 180 mm. Cuts tough materials. It is widely used in construction works.
- 230 mm. Used in the construction of buildings and various structures. Easily handles brick walls, planks and metal pipes.
The instructions for the device always indicate the maximum diameter of the nozzles. This means that smaller disks can be installed, but larger ones cannot.
Which grinder to choose
When buying angle grinders, it is worth considering the nature of the planned work. If you have to grind or polish outdoors, a battery or gas grinder is a better choice. For household needs, choose inexpensive network appliances. A professional repairman needs a tough tool. But its price is much higher.
In stores, when choosing a device, tell the sales assistant all the important criteria. Based on what he has heard, he will be able to choose the appropriate instrument and attachments to it.
