Cordless Engraving Pen, Brushless Rotary Tool with RGB Display, 8-Speed 22,000 RPM, 3 Collet Sizes (2.35/3.0/3.2mm), 67-Piece Kit for Metal Wood Glass Jewelry, Type-C Rechargeable
- PROFESSIONAL BRUSHLESS MOTOR 3X LONGER LIFESPAN & ZERO SPARKING-Engineered with an advanced brushless motor, this engraving pen delivers up to 3X the operational lifespan of conventional brushed models. The motor produces no sparking, minimal heat buildup, and consistent torque output across all speed ranges, ensuring stable performance during precision work on metal, wood, glass, and resin. Operating at under 50dB, it provides a quiet working environment suitable for detailed craftsmanship. (Note: Designed for fine detail engraving, not heavy-duty rotary applications.)
- 8-SPEED CONTROL WITH RGB DISPLAY 12,000 TO 22,000 RPM-Equipped with a precision 8-speed adjustment system and an intuitive RGB indicator, this rotary tool allows accurate speed selection from 12,000 to 22,000 RPM. Lower speeds (12,00015,000 RPM) are ideal for delicate materials such as jewelry, jade, and resin, while higher speeds deliver efficient cutting and polishing on hardwood and metal.

ERGONOMIC PEN-STYLE DESIGN 100G LIGHTWEIGHT BODY-Weighing only 100g with a slim, pen-shaped grip, this engraving tool is engineered for extended operation without wrist fatigue. The balanced center of gravity and non-slip surface provide superior control during intricate detail work, making it a reliable instrument for jewelry making, glass etching, wood carving, and metal engraving. Suitable for both professional artisans and hobbyists requiring sustained precision.
CORDLESS OPERATION WITH TYPE-C FAST CHARGING 90 MINUTES RUNTIME-Powered by a built-in 1500mAh lithium battery, this cordless engraver provides up to 90 minutes of continuous operation per charge, supported by USB Type-C fast charging for convenient power management. The wireless design eliminates cable interference, allowing flexible use across workshops, studios, and outdoor environments where power outlets are unavailable.
COMPLETE 67-PIECE ACCESSORY KIT WITH 3 COLLET SIZES ( 2.35MM / 3.0MM / 3.2MM )-This all-in-one kit includes three interchangeable collets ( 2.35 mm, 3.0 mm, and 3.2 mm), ensuring broad compatibility with a wide range of rotary accessories and aftermarket bits. The 67-piece set covers engraving, cutting, grinding, polishing, sanding, carving, and drilling applications across metal, wood, glass, plastic, leather, stone, jewelry, and resin. Integrated intelligent overload protection automatically disengages the motor when torque exceeds safe limits, safeguarding both the bits and motor for long-term reliability
Why is the E3 brushless rotary tool so quiet during operation?
The E3 uses a brushless motor, which helps reduce vibration and noise. Compared with traditional motors, the noise is reduced by 20%.
What accessory sizes is the E3 compatible with? Does the E3 come with extra collets?
The E3 collets accommodate accessories with diameters of 2.35 mm, 3.0 mm, and 3.2 mm. You can purchase replacement accessories based on these specific dimensions. Spare collets are included in your kit and are neatly stored within the case.
Can this tool handle precision sanding, drilling, or carving?
Yes! E3 is specifically designed for lightweight precision tasks. With a 22, 000 RPM brushless motor, it delivers exceptional control and speed for detailed work on soft materials. But not recommended for heavy-duty work.
Why does the tool stop spinning when I press down hard? Is it broken?
It is not damaged! When the applied torque exceeds the machine's load-bearing capacity, the overload protection mechanism activates to safeguard both the drill bit and the motor.
The overload protection has triggered, and the tool has stopped running. How do I restart it?
Simply lift the brushless rotary tool away from the workpiece to reduce the torque, and normal operation will resume.
