3.175mm Flex Shaft adapter Attachment Flexible Power Drill Extension Cable Chuck for Dremel Rotary Grinder Woodworking Tools with Wrench (Gold)

I will say I had to send the first one back cause the inner core snapped, though that could have been from many different things. however, upon return, I received replacement no issues and just like the first BEFORE it snapped it works like a dream. WARNING !!! the standard chuck that fits a Dremel will not fit this one it seems the threads are a smaller size, HOWEVER, it comes with a chuck already on it and fits both 3/8 down to 1/8 perfectly and snuggly.

I used to be a HUGE fan of Dremel rotary tools. I have been using them for years. But... I kind of stopped using it as much over the last few years. Why?The Dremel motor is rather large and bulky, which is why they sell a flex/extension shaft. The Dremel brand flex shaft is fantastic, but it is time consuming to attach, the possibility of losing small parts is always looming, and the hand piece is a bit wide for detail work in very tight spaces.This flex shaft has renewed my affection for my Dremel tool. Why?Because I just attach it to the Dremel using the chuck as if it was just another bit.Because the head of this is measurably thinner than the Dremel version.Because it is a very nice price.There are drawbacks. Because the shaft is exposed at the motor (about 1/8-1/4" shows) you have to be careful where you put the motor. Because of the small size, it gets a bit hotter, so letting it rest for a few minutes is highly recommended.But, overall, this is a solid addition to my toolbox. In fact, I often find myself using the extension shaft even when I do not need to. It is that convenient.

I've read the reviews and questions regarding overheating. This is not a Dremel brand tool, and you bought this at a reduced price, so some adjustments are required. I've used this for several hours and with a variety of bits. Early on, I experienced some overheating, but with a little lubrication--WD-40 or general purpose oil applied at both ends, the heat is not unreasonable and the tool works as you would expect. The advantage this tool has over the Dremel brand flex shaft tool is the slimmer profile of the tool itself. If that, and the cost, is of importance to you, likely you will be satisfied with this tool.

Had for 6 months used it 4 times then broke.The inside shaft snapped keeping the tip from rotating. Buying a Dremel now $5 more

It works really well with my dremel I use. I bought this to help with my gun building hobby with polymer 80s as my other dremel couldn't get what I wanted done. It works really really well for gun building. I haven't had any issues but I will update if I have issues. So far I would recommend this.

This product works great, when it works. I have purchased multiple of these because they break fairly easy. The ergonomics are the best so I have purchase multiple till I find something that is more durable but works just as good. Customer Service is nonexistent with the company.I have now had 2 that have broke the same way in a year.

I can't believe I waited so long before buying one of these, they're excellent. I probably have 15 hours on mine, haven't had any issues with it getting hot like other people have mentioned. I will say, it's generally best practice to avoid sharp bends in the flex shaft as they will increase load on the dremel, but other than that it's great! My dog agrees, he's a lot more tolerant of the dremel when the large noisy motor is away from him. It's also exponentially easier to manuver this little pen than it is to manuver the whole dremel.

The attachment did not fit my Drexel the way I had expected it to. If you do not really tighten the head with a wrench it will come lose and through the bit. After I was able to get the bit in and tightly secured, extension worked well until the bit loosened. I don’t know if I had a different Dremel series if that would have made a difference or not. With that said it was not a total failure. And the price was reasonable. Thank you.
