Many household and DIY projects require bladed tools or machines, whether it’s mowing the lawn or chiseling some wood. At some point, you’ll need to sharpen those blades or remove rust and corrosion from a steel tool. That’s where a bench grinder shines.
The best bench grinders can sharpen steel and remove rust much quicker and easier than doing it manually. Heavy-duty bench grinders typically feature two grinding wheels, often with different grits, to quickly sharpen blades and remove rust. On many grinders, the grinding wheels can be swapped out for metal brush wheels—a boon for cleaning metal connectors and spark plugs—or buffing wheels, which are designed for putting a fine shine on metal or plastic surfaces.
The best bench grinder is high-quality, easy to use, and protects your eyes from sparks and fine metal shards while you’re working. You should still wear eye protection, though.
