Tools and Hardware Reviews of Dremel 4486 MultiPro Keyless Chuck
Customer Review: Also compatible with the Dremel 1100-01 Stylus
Summary: 5 Stars
This is a useful addition to any Rotary tool. It makes changing accessories a snap. That is especially true if you would normally have to change collets along with the accessory. And if you want to use a bit with a non-standard shaft size then you really need this.
Aside from adding my "this is a must have with a rotary tool" comment I wanted to point out that it works perfectly with the Dremel 1100-01 Stylus 5,000 to 25,000 RPM Variable Speed 7.2-Volt Lithium-Ion Cordless Rotary Tool with Docking Station (another best in breed product).
BTW, I feel that honest, effective reviews take the place of first-hand experiences that are lacking in online shopping. I've always appreciated the help I've gotten from other reviewers and continue to return the favor as best as I can. If you thought this review was helpful please let me know by clicking on "Yes" button where it asks. If there was anything you thought was lacking or unclear leave a comment and I'll do what I can to fix it.
Customer Review: An absolute MUST if you own a Dremel
Summary: 5 Stars
If you're still using the little aluminum collets with the collet nut and the cheesy little collet wrench that your dremel came with, STOP IT. You're wasting your time. I put this keyless chuck on my dremel 8 years ago and it hasn't come off since. It's the hold-everything tip that adjusts for any size (well, anything smaller than 1/8") shanks. You need it.Customer Review: Awesome time-saver, but not for use with other attachments
Summary: 4 Stars
I rarely use the standard collet that comes with the tool any more, after buying this item. No more looking for a wrench (which I invariably loose), etc. Beware, though: I took for granted that it would be compatible with my chainsaw charpening attachment. It is not. If you use other attachments, don't expect to be able to use this at the same time. If you don't use other attachments...well...go on to the next review. Well worth the buy, in my opinionCustomer Review: Beware! This accessory is hazardous!
Summary: 3 Stars
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.Customer Review: Change for the best
Summary: 4 Stars
Great accessoey. Makes changing bit much faster and easier. No need to use a wrench to tighten the bit,just loosen to the left and tighten to the right. The bit holds tight throughout the operation of the tool. I highly recommend it.
