Review: Why did it take me so long?? - First time purchasing a CORDLESS Dremel - have 3 older corded. I have to say this was a smart choice. So much power! I’m taking my time working up to full throttle 😅 and the battery is still more than half after three separate uses with just one charge! Extremely versatile (slices through pvc lattice like butter). Great quality and weight for short or long work sessions. Noise is minimal and will vary somewhat in relation to power level and duration of use. The only thing I could ask for is a slightly better body. I have big hands (6’ woman) and it is a bit thick around the middle- not unreasonably so - just asking for a little better ergonomics when holding, like a slightly deeper pinch nearer the head for when a detail grip is desired ( I get that there has to be room for the battery to insert and yes, I own the grip attachment - not a favorite of mine). Otherwise, it is simply everything one would expect from the Dremel brand - including an excellent price. By the way, the original Dremel in my toolbox is at least 15 years old and still performs admirably within it’s abilities. Upgrading to cordless, though? Wow. Awesome! This was an actual purchase and I was not paid for the review.

If your tool is flashing green when it is turned on, set it 10 to 15k and try again. Toggle on and if it still flashes try again. Now to the review. This is a great tool. It's got plenty of power and can SAND through a board. Not just cut. With a SANDING DRUM you can go through a board. It doesn't bog easily above 10krpm. It is great for cutting bolts, cutting sheet metal, sanding metal and wood, rough and fine shaping in wood. Fine shaping in aluminum, polishing steel, rough axe or lawn blade sharpening, engraving, and much more I haven't done yet. The battery life is good, but it leaves some to be desired. It can be gripped like a golf club for grinding, and shaping, or like a pencil for fine and detailed work. The battery charges in 30 to 40 minutes. It is quite heavy, but not enough to stop most detailed work. I can't say much about durability, as I've only had it for a week, but I've got it covered on sawdust, metal dust and splashed with water lightly. This is a brushed tool, but there is not a way to change brushes, so I guess you replace it. Fine with me for 70$, but might be a deal breaker for some to replace every 150 hours. It is a great starter dremel though. You will have to buy a lot more accessories to fuel your rotary addiction, but at this price it's pretty easy to. The carrying case is a huge bonus. It fits my 110 piece accessory kit with the charger, tool and battery. I overall, a great buy. ## Frequently Bought Together - Dremel 8240-5 12V Cordless Rotary Tool Kit with Variable Speed and Comfort Grip - Includes 2AH Battery Pack, Charger, 5 Accessories, Wrench, and Tool Fabric Carry Bag - Dremel 160-Piece Rotary Tool Accessory Kit with EZ Lock Technology - 1/8" Shank - Cutting Bits, Polishing Wheel and Compound, Sanding Drums & Disc (710-08) - 20 Pcs Carbide Burr Bits 1/8" Shank Compatible with Dremel Milwaukee Metal Grinding Wood Stone Steel Carving Cutting Engraving Grinder Kit Attachment Rotary Tool Accessories Set Harder Than Diamond --- ## 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.lk/products/438902757-dremel-8240-5-12v-cordless-rotary-tool-kit-with-tool](https://www.desertcart.lk/products/438902757-dremel-8240-5-12v-cordless-rotary-tool-kit-with-tool) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-09-05*
