Buying Guide

  • Power and Motor: Consider the power output of the angle grinder. A higher wattage motor can handle tougher jobs and extended use. Look for grinders with motors in the range of 7 to 15 amps for concrete work. For more information on motor types, check out Popular Mechanics.
  • Disc Size: The size of the disc determines how deep you’ll cut into the concrete. Common sizes are 4.5 inches, 5 inches, and 7 inches. Larger discs are suitable for deeper cuts but may be harder to handle. Learn more about disc sizes on This Old House.
  • Speed and RPM: High RPMs can make quick work of cutting through concrete. However, adaptable speed settings are beneficial for versatility in different tasks. Look for grinders with variable speed control.
  • Comfort and Ergonomics: Grinding concrete can be labor-intensive, so a comfortable grip and ergonomic design are important. Look for models with anti-vibration handles and lightweight construction.
  • Safety Features: Angle grinders can be dangerous without proper safety mechanisms. Features like a safety guard, lock-off switch, and dust ejection system are crucial for safe operation.

FAQs

What is an angle grinder used for on concrete?

An angle grinder is a versatile tool used for cutting, grinding, and polishing concrete surfaces. It can remove excess material, smooth out rough edges, and prepare surfaces for painting or sealing. With the right attachments, it can also be used for tile cutting and metal work.

What disc should I use for grinding concrete?

For grinding concrete, use a diamond-tipped disc. These discs are designed to handle the hardness of concrete and provide a smooth finish. They are available in different grit levels, allowing you to choose the right one based on the desired finish.

Can I use a regular blade on concrete?

No, regular blades are not suitable for cutting concrete. They will wear out quickly and may break, posing safety risks. Always use diamond-tipped blades designed specifically for cutting concrete to ensure safety and effectiveness.

How much power do I need for a concrete angle grinder?

For concrete work, a grinder with a motor power of at least 7 to 15 amps is recommended. This power range ensures the tool can handle the demands of cutting and grinding concrete, providing efficient performance without overheating.

Are cordless angle grinders good for concrete?

Cordless angle grinders are convenient for their portability, but they may not provide the same power as corded models. For extensive concrete work, a corded angle grinder is generally preferred due to its consistent power output and longer runtime.

Conclusion

Choosing the right angle grinder for concrete tasks involves considering various factors such as power, disc size, speed, comfort, and safety features. Whether you’re cutting, grinding, or polishing concrete, the right tool can make all the difference in performance and results. By understanding these key aspects, you can make an informed decision and select a tool that meets your needs.
