How To Choose An Angle Grinder?

When it comes to choosing the best angle grinder for your needs, there's various things to consider. While the primary use is grinding down metal it also offers wood sanding and metal cutting. It can also be used for polishing. 

Angle Grinder Factors To Consider

Load Speed: This is how fast the disc can move. The slower the load speed, the quieter the device will be, but the less powerful it will be too. If you're looking for a commercial grinder, you'll want a high load speed, which will be noisier.
 
Soft Start: The softer the start, the easier the angle grinder is to handle. If you need something for a delicate task then it's better to have soft start as there's less kick. 

Voltage: The higher the voltage, the more power you'll ultimately get. Portable angle grinders often lack voltage and are slower. If you need something faster, you'll almost certainly need to purchase a corded angle grinder.
 
Disc Size: Often you can change the disc size depending on your individual needs, however if you're a beginner, choosing based on included disc sizes can be advantageous. Larger discs are better for deeper cuts while smaller discs are better for curved finishes.
 
Speeds: You can now purchase angle grinders that offer different speeds. For cutting metals you'll nearly always need at least 5,000 - 7,000 RPM while sanding might only need 2,000 - 3,000 RPM.
