2UUL DA85 CVT Pro Coreless Motor Grinder for Phone Repair

2UUL DA85 CVT Pro: Industrial-Grade Coreless Motor Grinding Pen

Elevate your micro-soldering precision with the 2UUL DA85 CVT Pro. Designed for the most demanding smartphone and tablet motherboard repairs, this is the first professional-grade grinder to utilize a Coreless Motor system. Unlike standard DC motors, the coreless technology provides higher torque stability, lower heat generation, and zero-vibration rotation—essential for working on high-density PCBs where even a 1mm slip can be fatal.

The "CVT" (Continuously Variable Transmission) allows for seamless speed adjustment, giving you the power of a heavy-duty drill in the ergonomic form factor of a surgical pen.

Key Technical Features:

• Coreless Motor Technology: Experience industrial-level torque. The lack of an iron core allows for rapid acceleration and a perfectly balanced rotating mass, eliminating the "wobble" found in cheaper grinders.
• Intelligent OLED Display: Stay in control with real-time feedback. The high-contrast screen displays your current RPM (100–12,000), torque output, and remaining battery life.
• Stepless Speed Control: The CVT dial offers infinite speed settings. Low speeds are perfect for delicate glue cleaning, while high speeds provide the power needed for camera ring cutting or grinding through stainless steel screws.
• Extended 8-Hour Battery: Powered by high-density lithium cells, the DA85 CVT Pro is built for all-day workshop use. Recharge via universal USB-C in under 90 minutes.
• Universal Collet System: Includes three interchangeable collets (up to 3.0mm), allowing you to use the included 10-piece 2UUL bit set or any third-party industrial grinding bits.

Technician's Note: When grinding a chip, always start at a mid-range RPM (approx. 5,000) and let the weight of the pen do the work. The DA85's coreless motor will maintain constant torque even as you apply slight pressure, preventing the bit from skipping.
