Equipped with a brushless motor that reaches 22000 rpm, a stylized 20 mm diameter body and dual power mode (800 mAh battery or on-hand use), this mini-rotary is intended for precision work in wood, metal or jewellery. The hard case includes 16 2.35mm attachments that automatically rise for a quick and tidy replacement.
Precise and adjustable power
The speed adjusts between 15000 and 22000 rpm via a front dial, offering stable torque and minimal bounce on delicate materials.
Built-in battery and wired mode
The 800 mAh cell provides up to 60 min of continuous work and recharges via USB-C in about 90 min; if the task is prolonged, simply plug in a 5 V / 3 A adapter and continue without interruption.
Lightweight and ergonomic design
At 184 × 20 × 20.6 mm and only 310 g with a case, its rubber-coated anodized aluminium chassis offers a non-slip grip and prevents the tool from rolling on the table.
Accessories and maintenance
It includes diamond bits, rubber tips, felts and twist drill, covering engraving, sanding, polishing or fine drilling tasks. The keyless tool holder allows you to attach consumables by turning the nose, without additional tools.
Security and control
An internal chip manages temperature and overhead; In addition, starting at 15000 rpm reduces bumps and improves control on small parts.
Comparative
Compared to a reference like the Dremel 8220—heavier (660 g), 2 Ah battery and 5000-35000 rpm range—, the Mijia favours portability and simplicity. The “pen” format relieves long sessions and the mixed battery-cable mode avoids stopping due to lack of charge, something that the competition does not always solve. The trade-off is the 2.35 mm calliper, less compatible with standard 3.2 mm accessories, and a lower power ceiling, so in more aggressive cuts, a more robust equipment will be preferable. Still, for modelling, restoration or light DIY, it offers an excellent size-performance ratio and cleaner handling in tight spaces than many classic models.
