Today we'll talk about how to choose a grinder, and the 2019 rating of angle grinders in terms of reliability, price and quality will tell you which model of an angle grinder is better to buy for different tasks.
Angle grinder, also known as angle grinder or in everyday life "grinder" - an indispensable thing for any workshop, car service or home craftsman of all trades. It is designed for grinding metal, cutting reinforcement, tiles and plaster, polishing, grinding and sharpening.
The ability to install a large number of attachments and accessories is what makes the grinders such versatile tools.
How to choose a grinder for home use
Disc diameter
- 100-115 mm - suitable for grinding, polishing and small jobs. Due to the shallow cutting depth, it is not suitable for cutting.
- 125 mm is the most popular disc size for household grinders. Allows you to make a cut up to 40 mm deep.
- 150 mm - irreplaceable if you need to cut concrete, thick metal or brick.
- 180 mm - suitable for angle grinders, which have to make deep cuts.
- 230 mm - can cut up to 70 mm deep. It is unlikely to be required in everyday life.
Power and speed
Two parameters are important here - W (or kW) and rpm. The power does not always depend on the size of the drive, and usually ranges from 500 W to 2.6 kW. For cutting not thick metal, 600-900 watts are enough.
RPM refers to the speed of the disc. With a large disc diameter, the speed is 7000-9000 rpm, with a small diameter - up to 12000 rpm.
Food
If you plan to use the grinder for several hours a day, we recommend opting for the wired model. It is independent of a charged battery and can be used all day long.
If you will be using the grinder for 1-2 hours a day, then the battery-powered model is perfect for this.
Important functions
- A good grinder must have a disc protection. Ideally, you should choose an angle grinder with a toolless adjustable safety 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 lacks such a brake. Without a brake, the disc will simply spin on its own until gravity stops it. Since angle grinder discs can reach very high speeds, they remain very dangerous.
- Soft start (another expression - starting current limitation) - allows you to start the motor without jerking.
- Dust extraction 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.
