Dremel 4000 collet end hot. With flexshaft,the shaft very hot in seconds. This is Brand new. Dremel says they never ever heard of this problem . They suggest I pay to have them check it out,and return shipping.
Perhaps you are bending the shaft too much, or the original lube in the flex shaft has been compromised. Take it back to the dealer, for an exchange.

Do you have a 'nut' on the end, or just a wide open shaft (1/3 inch or so?)
You need a collet nut to tighten bits, and maybe collets of varying sizes also (not sure about this particular shaft).

I dont think it should get that hot. Dremel has a program for the 225 Flex Shaft and for 17.90 they will exchange it for you. Send it to DREMEL 4631 E. Sunny Dunes Rd. Palm Springs, CA 92264. Their phone number is 1-800-275-2052. Hope this helps. Dave
SOURCE: I have a Dremel 300 and the shaft lock assembly
The "nub" on the shaft lock assembly (internal) has worn down and the assembly needs to be replaced.
If you feel competent to open your Dremel yourself (and it's not on warranty) then order the shaft lock assembly from Dremel (early 2011 price: $1.25, not sure how much postage & handling might be). After opening the tool you will find a metal ring and a small piece (the lock) which it holds in place around the shaft where the lock button is located. Remove the old pieces and replace with the new ones and reassemble the tool.
Otherwise you can send the tool to Dremel to be fixed.

There is a collet stuck in there. It was probably in there without any tool in place, then the collet nut was tightened. With no tool filling the hole in the collet, it collapsed and became small enough to be pushed too far in. Fortunately these collets are soft steel. Find a sheet metal screw that you can screw into the hole. That will allow you to pull the collet out. Discard that collet. These collets come in at least two sized to accommodate different sizes of tool shafts. Unfortunately the spare one you have is one of those sizes, and the one you extracted is probably the other. But they don't cost much and you can buy them where you buy dremel tools. Good luck, Al K
SOURCE: Dremel shaft lock spinning
Trying to fix a similar issue. The pin that gets pushed in by the button (and returned by the spring) seems to be fine. The hole in the rotating shaft that the pin fits into, however, is in the wrong place, so the pin never goes into the hole! All I need to do is somehow pull the whole front part of the shaft out about 1/16th of an inch, and it'd be fine. I just can't seem to budge it though. Any tricks, anyone?
