Buying Guide
Buying Guide: Large Angle Grinders
A large angle grinder is a powerful tool for cutting, grinding, and polishing. Choosing the right one is crucial for your safety and project success. Heres a quick guide:
Power & Size
Consider the motors amperage. For heavy-duty tasks like cutting through thick metal or masonry, look for an angle grinder with a motor of 13 amps or higher. The disc size affects how deep you can cut. Common sizes are 7-inch or 9-inch. Bigger discs provide a larger cutting capacity, but also add to the grinder’s weight and size.
Safety Features
Prioritize safety. Look for features like a guard that can be adjusted to deflect sparks and debris away from the operator. A paddle switch offers enhanced control and can shut off the grinder quickly. Consider a model with a soft start to limit the initial jolt and reduce the chance of the tool jumping during startup.
Ergonomics & Features
Consider how comfortable the grinder is to hold and operate. A side handle that can be positioned on either side or the top helps with control. Anti-vibration features minimize fatigue during extended use. Variable speed settings are helpful for adapting to different materials and applications, giving you more versatility.
