It’s a great little kit with lots of accessories but I’m very disappointed in the instructions. I had no idea how to attach anything. I tried to understand the picture of how to open up the top. Nothing made sense when looking at the picture. And I’m still sure I didn’t attach the little filing tube correctly. It slipped off all pieces I slid it on to. One piece held it long enough to make it work on my bad toe. But I’m hoping YouTube will have a video with instructions. Otherwise, I think this tool should work perfectly for what I need it for. I’ll try to update my review after a few more uses. ## Frequently Bought Together - HARDELL Mini Cordless Rotary Tool 3.7V, 5-Speed Rotary Tool Kit with 43 Accessories, Type-C Charging Power Rotary Tool for Engraving, Sanding, Polishing, Drilling, Grinding, Small DIY Crafts - 100PCS Polishing Buffing Wheel for Dremel Polishing Kit, Polishing Wheel for Dremel Tool Accessories, with 1/8" Shank for Dremel Buffing Wheels - Felt Polishing Buffing Wheel for Dremel Rotary Tool 80Pcs Accessories Wool Felt Polishing Pad Wheel Set for Rotary Tool Drills with 1/8" Shank, for Watch and Jewelry Polishing Kits --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/597559409-mini-cordless-rotary-tool-4v-5speed-42pcs-mini-drill-diy](https://www.desertcart.hk/products/597559409-mini-cordless-rotary-tool-4v-5speed-42pcs-mini-drill-diy) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-17*
