Can this cordless rotary tool be used for heavy-duty metal cutting or wood sawing?
No. This tool is designed for light-duty, precision crafts like jewelry polishing, creating resin, etching, and detail carving. Please rely on its high speed (up to 20K RPM) and apply light strokes rather than heavy pressure to avoid overloading.
How does the Smart Memory function work during crafting?
If restarted within 5 minutes, it maintains your previous speed gear. If idle for over 5 minutes, it automatically resets to Gear 3 (the optimal starting speed) to prevent accidental surface damage to your delicate workpiece upon restart.
How is the battery life? Is it convenient to charge?
Features a 2500mAh lithium battery with high-quality cells, providing 2-3 hours of continuous use—25% longer battery life than ohter products. Features USB-C charging, 4 LED power indicators, and memory function to save your last speed setting.
What shank size does it fit, and how do I tighten the bits securely?
It fits universal 1/8" (3.17mm) shank bits. We upgraded the collet nut to a professional flat-sided cap. Press the spindle lock button, insert the shank deeply, and use the included wrench to firmly tighten the flat cap before turning it on.
How should I charge the device, and can I use a fast charger?
Use the included USB-C cable. To protect the internal smart motherboard circuit from short-circuiting, always charge using standard 5V USB ports. Avoid high-voltage fast chargers (like 9V/12V phone chargers). The 4-LEDs track power.
