Dremel8240-5 12V Cordless Rotary Tool Kit with Variable Speed and Comfort Grip - Includes 2AH Battery Pack, Charger, 5 Accessories, Wrench, and Tool Fabric Carry Bag

Excellent Cordless Dremel tool that I purchased for sharpening my chain saws using a Dremel optional kit yet of course works with most all the other dremel accessories, blades, disks etc. Battery charges easily in its own charger and enables the tool to function at 35K easily. While more costly than a corded model the portability more than makes up for this. I have not expeienced any overheating. While the tool is a bit larger than a corded model I would order it again if needed.

The Dremel 8240 is a cordless, battery operated tool, that can be used indoors and outdoors equally well. 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.

We buy every year for our side business, rock peck repair. Works well, lasts for a couple years of heavy use.

It's mostly a great tool, except for one long-standing issue: When you're doing intensive, detailed work, you're all but guaranteed to press the collet lock button, which makes a horrible grating sound and may stop all tool motion leading you to think that you've just broken it!I just can't believe that this is still an issue after all these years. I can see how it might be difficult to relocate it, so put a cover over it or make it a slide switch or something else that doesn't engage merely by holding the tool!

Lots of power when you turn it on! Comes with handy carrying case with room for accessories

Received as advertised. Good price.

Didn't have enough use for this Dremel, as well the loop for hanging the unit was not well constructed and holes fot the bale not deep enough, the bale popped off with no real adjustment available. I returned it and will keep using my 4000 series with electrical plug!

Working in the Veterinary field, this Dremel is a must for pedicure & file! Really appreciate the adjustable speeds. Low & slow for puppies & small dogs, while those big pups require a higher intensity/speed. Good quality overall & good shelf life as long as you keep up with getting the nail dust out. Do use caution (esp w/ long coat dogs) & no constant contact as the heat level increases & could be uncomfortable for your puppers.
