Adjustable USB Drill Set — 5 pieces Key benefits One compact tool replaces multiple devices: functions as a rotary tool and an engraver pen so you can drill, etch, and shape without switching tools. USB-powered for maximum convenience: plug into a laptop, power bank, USB wall adapter, or other USB power source to work anywhere. Adjustable design meets varied tasks: the tool adapts to different working requirements so you can handle precision jobs and simple drilling with the same unit. Ready to use out of the box: the 5-piece set includes the pen-style rotary tool plus drill bits for immediate drilling and engraving work. What it does and why you need it Rotary tool and engraver pen in one: ideal for fine detail work, light drilling, and surface engraving where control and accuracy matter. Saves time and space: smaller and more portable than a full-size drill set, making it practical for hobbyists, makers, and repair tasks. Simple compatibility: USB power means you don’t need a special charger or battery type; use common USB power sources you already own. Important attributes Function: rotary tool and engraver pen with included drill bits for drilling and engraving tasks. Compatibility: USB-powered — works with standard USB power supplies (laptops, power banks, USB chargers). Size and handling: pen-style form for comfortable, precise control in tight or detailed work. Performance: adjustable to suit different working requirements; designed for light-duty precision tasks. Practical use scenarios Jewelry and crafts: engrave designs or drill small holes in beads, wood, or soft metals for custom pieces. Electronics and DIY repairs: drill precise pilot holes or modify enclosures and small components. Model making and hobby projects: carve, shape, and detail plastic, wood, or resin parts with controlled rotation and fine bits. What’s included Complete 5-piece set: pen-style rotary/engraver tool plus the supplied drill bits for drilling and engraving tasks. Notes Designed for precision and light-duty work.
