What's the difference between an angle grinder and an orbital polisher?

Angle grinders are high-powered tools for cutting and grinding with a disc that spins at high speed, while orbital polishers have a gentler motion better suited for finishing and buffing surfaces. Choose an angle grinder if you need to cut or remove material quickly, and an orbital polisher if you're finishing or polishing existing surfaces.

What power rating do I actually need for home use?

For light DIY tasks like polishing or grinding small projects, 500-900W is sufficient, but if you plan heavy-duty work like cutting steel or concrete, aim for 1000W or higher. More power handles tougher materials and sustained use without stalling, so consider your typical projects before deciding.

Does the disc size matter, and what size should I get?

Disc size directly affects cutting depth and work speed—smaller 4-5 inch discs are lighter and better for detailed work, while 7-9 inch discs cover larger areas faster but need more power. For general home use, a 5-inch grinder offers good balance between control and coverage.

What should I check about safety features before buying?

Look for dead-man switches that stop the tool when released, side handles to prevent kickback injuries, and adjustable guards that protect your hands. Avoid models with missing or poorly designed guards, as these significantly increase accident risk during operation.

Is a corded or cordless grinder/polisher better for my needs?

Corded models offer consistent power and run indefinitely, making them ideal for extended work sessions, while cordless versions provide mobility and convenience for quick jobs or tight spaces. Buy cordless if you value portability and short bursts of work; go corded if you do longer projects or need maximum reliability.
