It really works and is by far the most valuable accessory for the Dremel. It closes down to near 0 for the smallest of drill bits (much smaller than a sewing needle) yet still holds larger bits than the "large" hex collet. It is well made and durable, withstanding everything from concrete and tile dust to oily metal shavings. It must be tightened with considerable force to resist slipping under heavy use but that's to be expected.

I don't understand why Dremel doesn't include this great little chuck as a standard accessory with all their Multi-Tools. It is so much easier, faster and less frustrating than fumbling with the tiny collet and wrench that the tools come equipped with. If you change bits on your Dremel often, as most do, you will quickly come to appreciate this chuck. As for me, the 4486 is comparable to the Flex-Shaft as one of the single most worthwhile attachments available for adding versatility and convenience to my Dremel tool.

This chuck (which I consider to be essential) greatly enhances the convenience of any Dremel. You might be tempted to save the old collet device this chuck replaces, but before long you will discard it as useless trash. I do a lot of really miniature work and I find the chuck to be great for holding things as small as a 1/64th inch drill. I have one on each of my 3 Dremels.

Several other reviewers have commented on the tendency of this keyless chuck to wobble and loosen in use. In some 20 years of use of this accessory, I've also found this to be the case (the tool bit works loose during use about 1/3 of the time), but have also found that this is particularly dangerous at high tool speeds. I recently had the keyless chuck vibrate loose while using a cut-off disk. Despite the fact that I felt a vibration in the tool and hurriedly moved to shut it down, by the time I did so, the mandrel had walked its way nearly fully out of the chuck, bent sharply sideways, but luckily stayed stuck in the chuck jaws long enough for me to shut down the tool. Despite the fact that cut-off wheels are extemely light, the mandrel was dramatically bent to some 30 degrees. I can barely imagine at what velocity the mandrel would have shot off had it not snagged in the chuck jaws. Lightweight but high velocity objects can cause severe injury, so if you intend to use this thing, I recommend that you save it only for low-speed applications. Stick to the collet chucks for high speeds -- I personally have never, in some 20 years, seen one of these get loose while working with the Dremel.

An adjustable drill chuck for the Dremel power tool is a brilliant concept. Unfortunately the manufacturing precision is less than brilliant. I purchased the chuck for diamond drilling my wife's quartz crystals and gem stones in a water bath. The chuck jaws are eccentric (out of true) and a 1 mm diamond drill tip actually moves in a noticeably larger circle. This makes it difficult to start the drill in a hard surface and also causes water to be splashed about when drilling. I have owned large drill presses which are much closer to being true than this chuck. It might work OK for softer materials but I don't understand why it couldn't have been manufactured true in the first place.

While I do like the conevience of the chuck, it does not rotate 100% true. This causes a very slight wobble at the tip of any drill bit. I have tried 2 different chucks, but both yield the same results. I only use the chuck when absolute precision isn't required.

I am the owner of an older Dremel advantage as well as a Milwaukee rotary tool. Milwaukee doesn't produce or sell any accessories for it's rotary so I had to look for replacement collets after busting the only collet that came with it. I was looking to order new ones and I was surprised at the high price for such a simple but essential part.that search led me to the keyless chuck. I read some reviews and saw that some said it didn't turn true or that it that it wouldn't hold the bit after use. well I bought it anyway and I'm glad I did. Turns true for me and I switched out a cutting wheel, a grinder, and a sander and it never loosened or showed the slightest wobble.

In case I ever do something really tedious and exact, like sculpting a character Christmas ornament, I will still buy some back up collets just in case I find it does not spin true. But I am very, very happy with this accessory. No more looking for the tool and it makes short work of switching tips. Fits great on the Milwaukee.

This is an essential purchase if you own a rotary. Saves time and money on flimsy collets.

I consider the MultiPro chuck to be the best accessory ever made for the Dremel tool. When you're doing work that requires constant bit changes, the changing of collets to fit a bit of a particular diameter becomes a real frustration, and wastes time. So, needless to say, an adjustable chuck is a real boon for these kinds of jobs. Just loosen it to remove one bit, pop in another, tighten, and vwah-lah! The collet nut and collets become pretty much obsolete.
The chuck may seem somewhat pricey, but when you consider the time you'll save and the convenience you'll enjoy, it's well worth the extra investment.
