Hoto - SNAPBLOQ™ R-A04 Electric Mini Rotary Tool Kit (38-Piece)
HOTO SNAPBLOQ™ R-A04 TOOL KIT
One system. Endless configurations.

SNAPBLOQ™: The modular workshop revolution
The SNAPBLOQ™ system is based on magnetic modules that you can freely connect, stack and attach. This allows you to work in three modes: Workstation Mode (an expanded workstation with magnetic panels), Storage Mode (a space-saving vertical stack), and Compact Kit Mode (a handy kit you can take with you). This solution ensures that your tools adapt to the project, not the other way around.
Advanced brushless technology
At the heart of the device is a high-performance brushless motor that delivers consistent output power and exceptional rotational stability. Compared to traditional solutions, this technology offers significantly higher efficiency, quieter operation and a longer tool lifespan. Professional-grade power enclosed in a compact housing, ready for the most demanding micro-workshop tasks.

Precise control and HOTO Smart Chip
The R-A04 features stepless speed adjustment (Stepless Speed Adjustment) across a wide range from 15,000 to 22,000 RPM. This allows you to perfectly match the working speed to the material being processed and the specific task. The intelligent HOTO Smart Chip monitors the load and protects delicate components from damage, ensuring smooth response and the highest level of safety during operation.


Unlimited versatility
Thanks to its extensive set of 38 precision accessories, the R-A04 becomes a versatile hub for your creativity. The device lets you switch efficiently between vastly different tasks: from engraving and drilling in wood or metal to precise grinding and polishing of finished details. This wide range of applications means one tool replaces a series of specialist instruments, enabling comprehensive work on jewellery, models, acrylic and electronics.
Dual operating mode and efficient battery
A distinguishing feature of this model is its flexible power supply. The built-in battery provides around 30 minutes of uninterrupted wireless operation, while the USB-C port also allows you to use the tool in corded mode. This means you never have to stop your project because of a depleted battery. The included set of 38 precision accessories ensures you are ready to cut, grind or polish as soon as you take the device out of the box.
