How to Choose Angle Grinders
Motor Power
Look for a motor power of at least 7 amps for good performance. A higher amp rating, like 10 amps, allows for tougher jobs. This means you will have enough power for cutting, grinding, and polishing.
RPM Speed
Select a grinder with a speed of at least 11,000 RPM. Higher RPM speeds help you complete tasks faster. For heavy-duty tasks, 12,000 RPM or more is preferred.
Weight and Portability
Consider the weight of the grinder. Lighter models are easier to handle. If you need mobility, a cordless model may be best, but ensure it has a good battery life.
Safety Features
Look for models with safety features like a quick brake system. This helps stop the wheel quickly and prevent accidents. A tool-less guard adjustment is also useful for easy changes.
Warranty
Check the warranty period. A longer warranty shows confidence in the product’s durability. Aim for grinders with at least a two-year warranty for confidence.
