The 2UUL DA86 Mini Grinder Cordless Engraving Pen is an ultra-compact, high-precision electric rotary tool engineered specifically for smartphone logic board repair, micro-soldering, IC chip grinding, frame restoration, and delicate component carving. Designed with a lightweight, ergonomic pen-style body and a low-vibration precision motor, it provides smooth, jitter-free control under the microscope, allowing technicians to work on microscopic board traces and delicate silicon dies without risk of tool slip.

Equipped with a multi-speed adjustable power system and powered by a built-in rechargeable lithium battery with modern Type-C fast charging (supporting operation while charging), the DA86 ensures maximum workbench mobility without trailing wires. This kit comes complete with 10 high-precision U8 grinding and drill heads, making it a comprehensive, out-of-the-box solution for exposing PCB test points, grinding CPU/NAND shielding cans, clearing black epoxy underfill, cutting stripped screws, and polishing glass or metal frame edges.

Key Features

1. Smooth Low-Vibration High-Speed Motor: High-concentricity rotation prevents skipping, wobble, and trace tearing on microscopic smartphone logic boards.
2. Includes 10 Pcs U8 Precision Drill Heads: Comprehensive bit selection for micro-drilling, surface polishing, trace exposure, and underfill scraping.
3. Multi-Level Adjustable Speed Control: Allows technicians to match rotational speed to different materials, preventing heat buildup on fragile ICs.
4. Cordless Freedom with Pass-Through Charging: Built-in rechargeable lithium battery offers complete cord-free mobility and supports working while charging via Type-C.
5. Ergonomic Lightweight Pen Grip: Slim, balanced form factor reduces hand fatigue during long micro-soldering and bench repair sessions.
6. Universal Multi-Material Versatility: Engineered for grinding IC chips, cutting motherboard EMI shields, removing stripped screws, clearing hard epoxy, and detail engraving.
