Surprised How Freeing Lack Of Cord Is
on May 6, 2022
Posted by: James McLoughlin
from The Woodlands, Texas
[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 had rusted, which I used various Dremel Sanding Flap Wheels and Detail Abrasive Brush to remove rust to metal. The 8240 actually had the feeling of being lighter and easier to move-around/reposition than the corded Dremel 4000 I use, this from the drag of the cord itself. The 8240 had no noticeable power difference between it and my Dremel 4000 as I adjusted the RPM up and down the scale and in use in my project. The 12V Battery charged exactly as claimed with it Quick Charge and used two of the three bars in total for my project with no noticeable decrease performance as the Power Indicators lights dropped from three bars to one. Overall I would gladly replace my corded Dremel 4000 with the 8240, and as suggested in the User Manual for those who find a good amount of use for their Rotary Tool buy a second battery.

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 working. The battery power indicator is bright and right beside the speed dial. The on/off button is of a recessed slide type making it extremely difficult to turn on of off in error. There's a convenient hanging hook that stays locked out of the way until needed. The 12V 2.0Ah Li-Ion battery locks securely in the end of the tool and has a flat bottom making it easy to stand the tool on its end. The whole tool has great rubberized details making for sure grips as the tool is fully ambidexterous.
This tool can handle anything you throw at it and takes all the Dremel accessories and bits, which the other battery units can't. I expect this type of battery to hold its charge for months so it will always be ready when needed. The battery charging unit is designed with a solid base to sit on a bench or desk with a decent length cord going to its power pack.
The included case is well designed and made with room for a few accessories or extra battery. Though a soft shell, the top and bottom are semi rigid for tool protection. For casual use this kit has it all. But for someone who frequently uses their tool or takes it in the field, I'd suggest getting a spare battery.
As I said earlier, this is a substantial tool in size and weight, so for the casual crafter or someone doing fine work, this will probably be a little difficult to handle for prolonged periods. But not to worry, I'd suggest adding on the flex shaft and hanging this tool up by its built in hanger. Now you have all the power of this tool and no weight of bulkiness to hinder your working.
So I highly recommend this tool. Use it as is or add an accessory or two to make it your your ideal.

The Dremel 8240 performs great for all my projects
on May 2, 2022

[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 several wheels, but that"s ok. The important thing is that the 12 volt battery held up for four all for cutoffs that were needed. Next I installed a wood burr in the 8240 rotary tool so I could grind off excess wood that showed on a plant stand I'm building. The tool worked through all the glued wedge connections smoothly and uniformly very little vibration and most importantly no motor stall as I was cutting. I like this tool because I can adjust the speed to fit what I'm working on. This is one sweet tool.

The 8240-5 Cordless Rotary Tool is better
on May 5, 2022
Posted by: Big Man With Beard
from Loveland, CO
[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 weight of the 8240 tool with battery. I thought that it was way bigger and heavier than the 8200 but I was wrong. After putting both side by side and picking up both, I determined that they were about the same weight and size.
What I immediately liked about the 8240 was the rubberized grip of around the tool which gave excellent handling. Also, on the 8240 there is an indention near the front of the tool that help hold the tool when held in the pencil grip manner. The tool is well balanced was easy to hold using a pencil grip.
With the slightly higher speed and the higher voltage the harder tasks like cutting nails or sawing metal are easier. Also, I like the longer amp hours is a big plus.
