Brian kindly left this comment under Christmas #2. As it is chock full of useful Dremel-related miscellany, I am republishing it as a post, with his permission of course. Here it is, with a few minor modifications (and with a few comments from me in italics):
EZLock now has an extended range & overseas readers may find the SpeedClic info helpful.
EZ495 EZ Twist Nose Cap
Note: (As discussed here) collets have the advantages of better grip & less of the tool sticking out vs the chuck. That reduces vibration. If you use Router Bits in a chuck they often come loose.
The EZ Twist is just a new Nose Cap for the 4000 & older Dremels. It is used instead of the flat metal 90962 Wrench (spanner) to tighten & loosen the black Collet Nut & the silver Driver Cap or Driver Adapter used for the Flex Shaft (225), Mini Saw (670), & Right Angle Attachment (575).
I can say that the new EZ Twist Nose Cap works great. It can be retrofitted to most existing Dremels & just replaces the existing nose piece. It isn’t very expensive either at under $10. I have used it on a 395 Multipro as well as the 4000.
To use it you just unscrew it. It comes forward off the mounting thread & then the internal socket fits onto the Collet Nut to allow you to loosen or tighten it. You don’t have to take it off the neck of the tool to use it. Just slide it forward enough to fit the Collet Nut.
Simple & easy & nothing to go wrong.
Great that you can “upgrade” an older tool
The Accessory & Attachment Reference Guide has been updated and now includes the following:
- 191 high-speed cutter
- 150 drill bit
- 408 & 432 sanding bands
- 411, 412 & 413 sanding discs
- 932 & 85422 grinding stones
The 225 flex shaft is the only attachment that came with my Dremel 4000 kit. My father-in-law and I gave it a quick try when we were testing all the pieces that came with the tool, but then I put it away. Recently, after ongoing difficulties with making long cuts, I decided to give it a more thorough test.
Dremel says that it’s very important to suspend the rotary tool above the working end of the flex shaft. While they have apparently retired the 2222 flex shaft tool stand, at least in North America, they will happily sell you the 220-01 workstation that can do the same thing and more. An alternative solution is also available from a third party. The flex shaft is essentially a hollow tube with a square wire rotating inside of it. Failure to elevate the tool above the flex shaft can cause the internal wire to disengage from the working end, possibly causing damage. I also didn’t want the 4000 to rest on a table top while it was running, so I looked for a way to hang it. Continue reading
