Cut the cord and still performed like a pro!

Posted by: Jamie from Austin

[This review was collected as part of a promotion.] I was a little skeptical that a cordless rotary tool could perform as well as a corded version, but to my surprise it was very powerful and the battery life was excellent. I would highly recommend this as an alternative to being confined to being close to a plug in. I needed to cut off some small rebarb that was sticking up from my drive way concrete and didn't want to have to drag an extension cord out. Just walked over with this new tool and within minutes, all cut off and didn't have to wind up the extension cord. I can tell, I'll be using this a lot more often than I thought.

Perfection

[This review was collected as part of a promotion.] All You’ll Ever Need. This was able to replace my Dremel 4000 mainly due to the fact that I need to work on things away from an outlet and don’t want to bring an extension cable with me, the biggest pro to this beauty is that it is able to have the extendable, flexible shaft attached to it.

Heavy duty workhorse.

[This review was collected as part of a promotion.] The 8240-5 is a workhorse. The largest Dremel tool I have. Charges in a good amount of time. Charge lasts a decent amount of time. Uses all the attachments I have. Great for large jobs. I installed a new radio in my car, and had to remove some interior material to get the radio to fit properly. The 8240-5 barely had room to fit. It was tight. It cut through very easy using a cutting disc and I was able to install my radio. I had surface rust on my passenger side rear wheel well. I used the stainless steel brush attachment and cleaned the rust away. Then primer and painted. I can't wait to find the next project. The 8240-5 is awesome. Heavy duty. Great for large projects.

Wow factor

[This review was collected as part of a promotion.] This is my 2nd cordless Dremel. Comparing Dremel 8240-5 to my old Dremel Micro is like comparing apples to oranges. The Dremel 8240-5 blows the Dremel Micro out of this universe. The 8250 is bigger, has more power and I was able to finish an entire project with just the initial charge. Its mind blowing. I am utterly shocked but not surprised. I have never had a problem with any of my Dremel product. Keep up the good work Dremel and I would absolutely love if Dremel came out with a new Dremel Lathe machine.

Power carving with 8240-5
on April 30, 2022
Posted by: She Shed Carvers
from Wisconsin
[This review was collected as part of a promotion.] I am a power carver, I use a flex shaft and a reciprocal carving flex shaft . It is great to carve out side ,weather permitting, no power cords means I can cave any where. The 8249-5 has the power I need . So far the battery life is good. When using it with out the flex shaft it feel a bit heavier and a bit bigger than my 8220. Also the grip is to the front of the tool not the back .
The case is cloth which I most likely won’t use , I need case with more protection.
The hard case you can stack things on top not with cloth. That being said a case is not important to me . I build cases which hold several of my tools , accessories and chargers. I haven ‘t yet but will be using it to sharpen my chain saw .It will be my main dremel now.

[This review was collected as part of a promotion.] The Dremel 8240 is a great tool. It is easy to hold, has a lot of power for a 12v product and it charges very quickly with little down time. All the attachments are great with the product. You can use it for a multitude of tasks
