Question: Is this a 1/4 shank?
Document: I purchased this kit and some cutoff wheels to cut 1/4&#34; aluminum for a hobby project. They worked better than I had expected. They wear great. The EZ lock is so much easier that trying to screw discs to the end of a shaft.
In a review of the Proxxon rotary tool I mentioned that I used this item. I cut through a security cable much easier that I would believe. After cutting through the cable I noticed that it was still the same size as the original. I use a lot of cut off disks and this is the best I've run across. I usually use the 1 1/4 inch fiber cut off disks. This is great and the easy lock is better. Just love the easy lock.
Cuts really fast without compromising disc wear. So far I have only cut 3/4" metal conduit, cut really fast at high speed, with no noticeable wear.
Does just it's advertised to do. The fitting takes a little while to get used to, as it is different from other standard Dremel tools the way it needs to be positioned on the shaft. I used it to cut 1/16&#34; wire rope, and it did the job.
For the money, these should last longer than 5 minutes on the Dremel. I used them at 2500 RPM on motorcycle frames to cut off the tabs or cut through tubing and they give me about 4-6 inches of cut before they're garbage. These things aren't cheap! But I need the precision over the angle grinder so I'm stuck buying bajillions of these.
This is a simple 1 second procedure that doesn't require any special tools. It is a true time saver for the hobbyist or gearhead that makes use of cutting wheels for projects.The downside is the cutting wheel itself. The labeled surface is not very abrasive, so you can't use that side to grind stuff or smooth out surfaces.
Most likely because the cut was quicker and didn't have enough time to build up more heat.Pros:  Cut like a pro, easy to install.Cons:  I felt that the price was quite high for as much cutting as I think they will do. If it included 1 or 2 more, it would be more inline. Hence, -1 star.
4 star b/c of price. Way expensive for what it is. But it is a good design well executed. The locking system works well and the cutting discs last a lot longer than the Fiber Reinforced types and they are a heck of a lot easier/faster to change discs. I wouldn't attempt anything substantial with it but for small jobs in tight places it's just thing.
I use the dremel to cut out odd shapes from 1/8 in aluminum. In an hour I often go through 5-6 discs. I now only use 2-3 and they are very easy to change. Well worth the extra money, since you get the same number of cuts out of them and save time!
I had to cut an old gas-light pipe that was up in my ceiling and stood in the way of an upgrade to my wiring. The pipe protruded down through the ceiling and into an electrical box. There was no room to use a reciprocating saw through a little 4 inch hole, no room to use an oscillating multitool, no room to use a manual pipe cutter. My Dremel with a cut-off wheel seemed like the perfect solution.
Answer: no
