About This

• High-Speed Motor Up to 28,000 RPM Powered by a robust high-performance motor that reaches up to 28,000 RPM – significantly stronger than typical 4V rotary tools (usually capped at 18,000 RPM). This cordless rotary tool delivers enough torque and speed to cut, grind, polish, and engrave on wood, metal, plastic, glass, stone, ceramic, and resin. Perfect for both professional craftsmen and DIY enthusiasts.
• 4000mAh Battery & USB-C Fast Charging Built-in 4000mAh lithium-ion battery provides up to 90–120 minutes of continuous operation (depending on speed and workload). The USB-C fast charging port allows you to recharge via laptop, power bank, car charger, or wall adapter in just 2–4 hours. No more hunting for wall outlets – take your work anywhere, from garage to backyard to job site.
• Real-Time Digital Display Features a bright digital screen that shows the current speed gear (1–6) and remaining battery percentage. Before you start a task, you can precisely select the right speed for your material. During use, keep an eye on battery level to avoid sudden shutdowns mid-project. Complete control at your fingertips.
• 80-Piece Versatile Accessory Set Comes with 80 high-quality attachments including cutting discs, grinding stones, drill bits, sanding bands, polishing pads, and more. The universal 1/8-inch (3.2mm) collet fits most standard rotary tool accessories on the market. Switch between engraving, drilling, sanding, cutting, polishing, and grinding in seconds – everything you need is right in the included storage case.
• Safety Lock & Ergonomic Lightweight Body The automatic spindle lock prevents accidental startup when the tool is turned on, ensuring safe operation. The soft-grip rubber housing reduces vibration and provides a non-slip hold even with sweaty hands. Weighing only 0.87 lbs (approx. 395g) , it feels like holding a marker pen – comfortable for extended use, ideal for women, seniors, and beginners. Great for home DIY, model making, wood carving, and jewelry repair.
