Product Overview
- This premium mini disc sander adopts a high-efficiency brushless motor, far more powerful and stable than modified hard-drive grinders. Built with a solid 3-inch aluminum alloy sanding plate and stepless speed control, it handles polishing, grinding, sharpening for metal, stone, wood, jewelry and miniature craft pieces. Two complete versions available: wired plug-in model with built-in power adapter, and portable rechargeable battery model with long runtime. Ultra-compact lightweight aluminum body, hook-and-loop sandpaper design for fast pad swapping, ideal for hobbyists, watchmakers, jewelers and miniature DIY crafters.
✨ Core Premium Features
1. High-Speed Brushless Motor, Surpasses All DIY HDD Modified Grinders
- High-torque brushless core delivers stable high RPM with zero power drop during heavy grinding. No weak vibration or insufficient torque common with repurposed hard drive motors, supporting consistent rough shaping to mirror polishing for tiny workpieces.
2. Solid 3-Inch CNC Aluminum Sanding Plate
- 80mm integrated aluminum turntable offers flat, balanced rotation with minimal wobble. Hard-wearing metal base prevents bending during long hours of sanding, far more durable than plastic disc platforms. Hook-and-loop surface lets you swap grit sandpaper pads in seconds.
3. Stepless Infinite Speed Control Knob
- Rotary adjustment knob delivers full-range variable speed to match all finishing tasks: low speed for delicate jewelry polishing, high speed for fast metal deburring, wood carving and knife sharpening.
4. Two Practical Versions For Different Scenarios
-
Plug-In Wired Version
- Built-in integrated power supply, standard 8-figure power socket, plug-and-play with included power cord. Unlimited continuous runtime for long workshop grinding sessions, no battery capacity limits.
- Rechargeable Portable Version
- Built-in 12V 2200mAh large-capacity lithium battery, over 3+ hours of continuous use on a full charge. Fully cordless design for mobile repair, outdoor crafting and off-table handheld polishing jobs.
5. Ultra Mini Portable Aluminum Alloy Body
- Compact dimensions: 12cm length × 5cm height, lightweight handheld build that takes minimal bench space. Sleek grooved aluminum housing with excellent heat dissipation, clean minimalist industrial appearance.
6. Wide Multi-Material Compatibility & Low Consumable Cost
- Works flawlessly on metal, stainless steel, stone, jade, wood, resin, watch components and handmade jewelry. Compatible with universal 3-inch (75mm) hook-and-loop sand discs, widely available at low cost from all craft suppliers. Every order comes with 2 free 180-grit sandpaper pads.
7. Simple User-Friendly Operation
- Independent power on/off switch for instant startup/shutdown. Smooth, easy sandpaper replacement without extra tools. Note: For slippery tabletops, place a cloth mat underneath to prevent minor sliding at max speed.
