The HOTO SNAPBLOQ™ R-A04 Mini Rotary Tool Kit (38-Piece) is built for creators who value precision, mobility, and an organized workflow. Designed with a pen-size form factor and powered by a high-efficiency brushless motor, it offers smooth control for intricate tasks—from model building and DIY repairs to fine polishing and light engraving.
Its modular SNAPBLOQ™ storage system keeps every bit and accessory neatly arranged in sliding trays, making it easy to switch between tools without interrupting your creative rhythm.
Below is a clear and practical breakdown of each accessory and what it’s built to handle.
1. Grinding Bits — For Shaping With Accuracy
Grinding bits are the go-to attachments when you need clean, controlled shaping. Perfect for metal, glass, ceramics, and gemstones, these bits excel at fine grinding tasks. Whether you’re refining an edge or sculpting a small detail, they offer consistent performance with minimal vibration.
2. Drill & Milling Bits — For Clean Cuts and Detailed Engraving
When your project calls for precise drilling or carving into wood, plastic, or soft metals, these bits deliver. Drill bits create clean entry points, while milling bits handle controlled engraving and material removal. Together, they give makers a versatile toolkit for both structural and decorative work.
3. Wool Heads — For High-Gloss Finishing
Wool heads are designed for the final steps of surface refinement. Ideal for metal, glass, and wood, they provide a smooth finish and help remove minor imperfections. When you need a consistent, high-gloss polish, these heads make the process effortless.
4. Rubber Heads — For Smoothing and Pre-Polishing
Rubber heads bring a softer touch, perfect for metal, glass, and plastic. They gently smooth surfaces, remove fine scratches, and prepare materials for higher-gloss polishing. Excellent for users who need more control during early finishing stages.
5. Wool Wheels — For Mirror-Level Buffing
For the deepest shine, wool wheels are the finishing champions. Suitable for metal, jade, and gemstones, they enhance final clarity and bring out a mirror-like polish. They’re essential in any workflow requiring refined, professional finishes.
6. Polishing Block & Brush — For Cleanup and Maintenance
A clean workspace leads to better results. The polishing block and brush help remove debris from abrasive heads and work surfaces, ensuring your accessories perform at their best. Use them regularly to extend tool life and maintain consistent output quality.
A Compact System Designed for Everyday Use
Beyond the accessories, the R-A04 keeps things straightforward: a quiet brushless motor, smooth speed adjustment from 15,000 to 22,000 RPM, and an 800mAh battery that supports both cordless moments and longer plugged-in sessions. The standardized 2.35mm bits and the modular SNAPBLOQ™ storage give the tool a sense of order that’s rare in small rotary systems.
