About this product
Detailed indoor DIY or working in the garage? The Dremel 8240-5 is a cordless rotary tool that handles cutting, grinding, sanding and polishing. It's powered by a 12V Li-Ion battery so you'll move freely without cables. The motor delivers the same strength as corded Dremel multi-tools but you won't be tied to a socket. You'll work in dark corners using the 360 LED light for better visibility. Variable speed reaches up to 33000rpm for precision control across different materials. The motor brake stops rotation immediately when you switch off for safer operation.
You'll swap accessories quickly with the integrated spanner in the EZ twist nose cap. The battery indicator shows remaining charge at a glance so you won't get caught out. It's got a soft grip handle that reduces fatigue during longer sessions. Charging takes just 65 minutes to get you back to work fast. This cordless tool weighs only 0.66kg so it's easy to handle overhead. The kit includes five quality Dremel accessories, one 12V battery pack and a charger.

Useful tool for portable use. Get a spare batteryh
I was undecided about adding a cordless Dremel to my existing (Dremel 4250) model but I'm glad I did. One piece of advice: get a spare battery for it. The supplied battery only lasts about 45 mins to 1 hr. I got mine (new) on Ebay. The Dremel website shows a battery available and the claim it fits this Dremel 8240 but it does NOT fit!...😡. So make sure you get the same battery as the supplied one. The tools you get with this are basic but most Dremel fans will have a separate set of tools. The 'quick change' multi chuck is a worthy addition too and makes swapping tools a LOT easier. Overall I'm glad I got this and it was a smooth and easy transaction from Argos and the price was good too.

Great tool
A bit bulkier than I thought it would be. Also sometimes have to slide button back up on second attempt to turn on. As doesn't always come on first attempt.

Shopped around and at the time Argos had the best price, it’s a very handy tool, don’t use it all the time, it has it uses when nothing else will do, it’s easy to operate, very high RPM, which is what I needed, glad I bought one, highly recommended

Thank you for using Argos Q & A
Hi Will
Contact was made with the supplier for you.
They say - the Dremel 8220 is designed to be held in a number of ways that is comfortable for you depending on the application;
Two handed
Pencil grip – using the round EZ Twist nose cap to hold like a large pen.
The black coloured Softgrip rubber will help guide your hand placement. There are additional attachments, such as the Dremel Flexible Shaft and Dremel Detailers Grip that can be purchased separately that will help you hold the tool more comfortably for extended periods when working on detailed applications.
Thanks for using Argos Q & A
Hello Brian,
After checking with our supplier, they have advised: The Dremel 8220 is not supplied with a chuck, it is supplied with a Collet and Nut for securing accessories. The collet is compatible with accessories that have a shank diameter of 3.2mm only.
To use accessories with a different shank diameter another compatible collet or a Multi-Chuck would need to be purchased separately.
Hope this helps
Thank you for using Argos Q and A.
Hello Me,
After checking with our supplier, they have advised: Unfortunately the battery life is heavily dependent on the application you are performing, the speed you’re running the tool at and is also effect by the amount of pressure you place on the tool. For example, if you want to cut stainless bolts you need the highest speed which will use the battery charge a lot more quickly than if you are polishing metal on a moderate speed.
Hope this helps

Hi Steve
I have looked into this for you and the case is not included with the Dremel 8220 Cordless Rotary Tool.
I shall ask for the website to be corrected.
Thanks for using Argos Q&A
Hi there,
Assuming by “trailer” it will be metal, as long as you have the correct accessory then yes the 8220 will engrave no problem.
