Today we’ll talk about how to choose a grinder, and the 2019 angle grinder rating on reliability, price and quality will tell you which model of angle grinder is best to buy for different tasks.
An angle grinder, also known as angle grinder or “grinder”, is an indispensable item for any workshop, car service or home handyman. It is designed for grinding metal, cutting rebar, tile and plaster, polishing, grinding and sharpening.
The ability to install a large number of nozzles and accessories is what makes grinders such universal tools.
How to choose a grinder for home use
Disc diameter
- 100-115 mm - suitable for grinding, polishing and small work. Due to its shallow depth, the cut is not suitable for cutting.
- 125 mm is the most popular disc size for household grinders. Allows you to make a cut to a depth of 40 mm.
- 150 mm - indispensable if you need to cut concrete, thick metal or brick.
- 180 mm - suitable for angle grinders, which have to perform deep cuts.
- 230 mm - can do a cut to a depth of 70 mm. It is unlikely to be required in everyday life.
Power and speed
Two parameters are important here - W (or kW) and rpm. Power does not always depend on the size of the disk, and usually varies from 500 W to 2.6 kW. For cutting not thick metal, 600-900 watts is quite enough.
Revolutions per minute refer to disk speed. With a large diameter of the disk, the speed is 7000-9000 rpm, with a small diameter - up to 12000 rpm.
Nutrition
If you plan to use the grinder for several hours a day, we recommend that you opt for a wired model. It does not depend on the presence of a charged battery and can be used all day.
If you use the grinder 1-2 hours a day, then the battery-powered model is perfect for this.
Important Functions
- A good grinder must have disk protection. Ideally, you should choose an angle grinder with an adjustable tool-free guard.
- The disc brake is responsible for slowing down and stopping the disc when you release the trigger. This is an important safety feature and you should not buy an angle grinder that does not have such a brake. Without the brake, the disk will simply spin by itself until gravity stops it. Since angle grinders can reach very high speeds, they remain very dangerous.
- Soft start (another expression - inrush current limitation) - allows you to start the motor without jerking.
- Dust removal system - a nozzle is included with the grinder, which is connected to a construction vacuum cleaner.
Which manufacturer's angle grinder is better to buy
The most famous Russian and foreign manufacturers of grinders are: Interskol, Zubr, Makita, Stanley, Black & Decker, Bort, Bosch, Metabo and Hitachi.
