Powerful enough for smaller jobs, buy a dremel if you want a professional device, but for little tasks it's great. You can possibly use dremel bits on this device. Battery life unknown as just got it. ### ⭐⭐⭐⭐ Nifty little device *by J***N on 26 July 2024* So far so good with this item, though a couple of niggles lose a star. The drill bits are not very sharp and blunted very quickly, and there are only three of them. I have ordered another set of mini bits so I'm hopeful that will help. The box doesn't close properly and this must have been known by the seller, as they provided an elastic band. Helpful I suppose but I would prefer a functional box. The other issue is having to frequently change collets when changing to different attachments, and it seems of the shaft size were standardised less collet changing would be required. Other than that, it charged well, lasts long enough (so far, I haven't had to recharge yet) and it's really helpful for my craft projects. So far I've drilled a few holes in various materials and used the different sanding tools for smoothing and shaping a small project in clay. It's powerful enough for my needs, not too loud and quite versatile. ## Frequently Bought Together - Cordless Mini Rotary Tool Kit - 5 Speed Adjustment USB Rechargeable Mini Grinder with Light 50 Accessories Multi-Purpose Power Rotary Tool for Sanding Polishing Drilling Etching Engraving DIY Crafts - Cutting Wheel Set for Rotary Tool, HSS Cutting Discs Circular Saw Blades for Wood Plastic Metal Cutting (One Screwdriver) - Tungsten Carbide Steel Double Cut Rotary Burrs Set for Rotary Tool, 10pcs 1/8 inches Shank Fits Rotary Tool for Grinder Drill, DIY WoodWorking Carving, Metal Polishing, Engraving, Drilling --- ## 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.com.br/products/352367990-cordless-mini-rotary-tool-set-64pcs-accessories-5-speed-5000](https://www.desertcart.com.br/products/352367990-cordless-mini-rotary-tool-set-64pcs-accessories-5-speed-5000) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-07-19*
