In 2025, these tools are more advanced than ever, with a wide variety of options for cutting, grinding, sanding, and polishing metal, wood, stone, and even tile. Whether you're a professional or a hobbyist, choosing the right angle grinder can elevate the quality of your work. Below, we've compiled the most frequently asked questions to help guide your decision.
What is an angle grinder used for?
An angle grinder is used for cutting, grinding, polishing, and sanding various materials, including metal, stone, tiles, and concrete. It's an essential tool for heavy-duty tasks like grinding welds or cutting through rebar.
What’s the difference between corded and cordless angle grinders?
Corded grinders are more powerful and are ideal for long, continuous tasks. Cordless grinders offer more portability and convenience, especially for lighter jobs or work in areas without power outlets. Cordless models are usually less powerful but are improving in performance with newer battery technologies.
What size angle grinder should I buy?
Angle grinders come in several sizes, typically 4.5-inch, 5-inch, 6-inch, and 9-inch models. Smaller grinders are more suitable for light tasks like sanding and polishing, while larger grinders are better for heavy-duty cutting and grinding.
How do I choose the right disc for my angle grinder?
The right disc depends on the material you're working with. For cutting metal, use a cut-off disc; for grinding metal or stone, use a grinding disc; and for polishing, use a polishing or buffing disc. Make sure the disc is rated for the size and power of your grinder.
What is the importance of safety when using an angle grinder?
Angle grinders are powerful tools and can be dangerous if not used properly. Always wear safety goggles, ear protection, gloves, and a dust mask when grinding or cutting. Many grinders also include a safety guard that should be adjusted properly before use.
How much power do I need for an angle grinder?
Power is measured in amperage (corded models) or voltage (cordless models). For lighter tasks, a 4.5-inch grinder with 6-8 amps is sufficient. For heavier, industrial tasks, a 9-inch grinder with 12 amps or more is recommended.
Can I use an angle grinder for cutting wood or tiles?
While angle grinders are mainly designed for metal and concrete, they can be used for cutting wood with a specialized blade (though not ideal for extended use) or tiles with a diamond blade. Always ensure you're using the right disc for the material.
How do I maintain my angle grinder?
Keep your angle grinder clean and regularly check for loose parts. Ensure the disc guard is securely in place, and regularly inspect the disc for wear and tear. Clean the vents to avoid overheating and replace worn-out parts as needed.
