Rotary tools can be used for all kinds of tasks, from drilling, cutting, carving, to polishing, sanding, sharpening, and engraving a variety of materials including wood, metal, and glass.
Are rotary tools safe?
Rotary tools are safe, but they operate and rotate attachments at very high speeds, so you should always wear gloves and a face shield or safety glasses when using them, secure any loose hair or clothing, and consider a face mask or well-ventilated space if you'll be grinding anything that makes a lot of dust.
