Works fairly decent, just have to get use to the fact that you have to be patient and take your time while drilling or cutting. Can't try to push it to hard, will cause it to cut off, so have to restart.

Love no cord!
Worn horseshoes are used to create western art by crafters. The issue, however, is that they are worn by the horse through mud, gravel, and other abrasive materials for weeks/months. During that wearing they also rust. Sandblasting is often used to try to clean them up, but when my friend asked me if I could do something with her horse's used shoes, I decided to see what the Dremel 8240 could do, since I didn't have access to sandblasting equipment. The picture below doesn't do justice to how ru...

If you can only have one, Make it this one
[This review was collected as part of a promotion.] I was surprised by the size and weight of this tool - very substantial. I own two other Dremel battery rotary tools and I find that each excells in a particular area and falls short in another which is true for all tools. I have to say that if you can only afford one rotary tool, battery or electric, this is the one to get. It's strong running and fairly quite. The speed control dial holds its position and isn't easy to mistakenly change while...

Dremel battery is junk!!
I have the Dremel 8220 and although a few years old it has only been used a couple of times. I pulled it out this week to use it a d it won't run. Charger works but battery apparently doesnt charge b/c tool is dead. Seems like a common problem with this brand/battery. For the cost of this tool, Dremel do better! So disappointed in this product 😞

Great rotary tool for a novice Dremel user.
[This review was collected as part of a promotion.] I found the 8240 a very good rotary tool. I will start by saying that the 2ah battery is not the best of batteries, and I would really have liked to get a second battery included in the kit. The added tool tray is rather lacking to tell the truth. The cutting wheels are of the old design that use (an included) arbor with the small screw that retains the wheels. I kind of consider this kit as something that was thrown in just to give the new...

Surprised How Freeing Lack Of Cord Is
[This review was collected as part of a promotion.] First time I have used a Dremel Cordless Rotary Tool in my 30 years of owning and using varied levels of corded Dremel's. I have an added reason for liking this Cordless version outside of the standard product measures, I now have limited use of my right arm after a fall and elbow surgery, which is where I want to start my review. My project with the Dremel 8240 for review was cleaning and repainting a simple "In Ground" Garden Hose Stand which...

The 8240-5 Cordless Rotary Tool is better
[This review was collected as part of a promotion.] When I received the 8240 Rotary Tool, I was excited to see what had changed in the wireless tool since the 8200 tool that I own. The first thing I noticed after opening the box was the soft case as apposed to the hard case that came with the 8200. At first, I was disappointed with the case but after opening it up I was pleased with the arrangement and the straps to hold down the tools. The second thing that struck me as odd was the size and wei...

Dremel and remodeling
[This review was collected as part of a promotion.] In remodeling a den, we purchased a small, corner unit to use for a printer stand and TV accessories holder. Once assembled, I got the idea that it could hold the external TV speaker as well. The speaker, unfortunately, was just a bit bigger than the angled corner cabinet could handle. However, I noted that I could cut an opening in both sides to allow the speaker corners to protrude without being visible from the cabinet front. Once again ...

The Dremel 8240 performs great for all my projects
[This review was collected as part of a promotion.] I recently got my Dremel 8240 rotary tool and I have been ever so happy with the ability to work on outdoor projects without dragging a extension cord through the back of my property in order to perform a simple grinding, cutting, shaping or polishing operation. Thank you Dremel! I first needed to add steel supports for my plants in my garden and the cutoff wheel used with the 8240 worked great for cutting the steel to lingths (used up severa...
