Review: Picked during Prime Deals and have no regret. - IMPORTANT! 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.

It is powered by a 12v Lithium-Ion battery with home charger, extra batteries can be purchased for more outdoor time. The tool has variable speed from 5,000 to 35,000 rpm controlled by a small rotary dial. Build quality is very good ant these tools will stand up to hard wear. Very easy to use, the size is not much longer that the ac mains version. The design looks very good with its two tone light and dark grey body. For its size it is very light weight and it works great. I love it as I can usit for little jobs on my car as well as the workbench. I would advise owners to invest in a Dremel 3-jaw chuck wich makes using small drills a lot easier. Great tool highly recommended. ## 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.ie/products/438902757-8240-5-12v-cordless-rotary-tool-kit-with-variable-speed](https://www.desertcart.ie/products/438902757-8240-5-12v-cordless-rotary-tool-kit-with-variable-speed) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-06-06*
