Coupler between motor and chuck disintegrated, where can I get a replacement coupler for a craftsman rotary tool model# 572.610011? Thx

usually there is a coupling to connect the 2 parts I would think that it has cracked. If you have the brand and model number get back to me and I will try and find the part number for you or you can go to their website and look it up.

Undo the chuck nut and then knock the spindle shaft of the sanding disc in lightly. This should release the collet's grip on the shaft. If the shaft has been pushed all the way into the chuck, remove the collets and nut and try separate the collet segments to release it from the shaft.

You will most likely need to purchase a used parts unit - look on Ebay they're very cheap.

These are fairly easy to disassemble and get back together, take it apart and find out what got stripped, It might be an easy fix, then again, it might be going back to sears. They will take it back no matter what. Hope this helps.

it is a chuck...of sorts. There should be a button to lock the shaft and then you can use the wrench it came with to loosen it.

Common issue with these, the plastic flex coupling is broken-

Disassembly on my model involved the following:
Remove the four Torx screws on the body, then unscrew the front end cap at the front of the tool to expose two more screws. Separate the two halves of the body to see the brittle and broken yellow coupling.
Replace with the new white coupling and reassemble. Buy spare couplings as they don't seem to last all that long.

Do you have any kind of a clutch on this drive ? I may be in bewteen settings.
Please let me know

The Dremel 275 (and other series) have a plastic coupler and spline that connect the motor shaft to the collet shaft (where the tools attach). The plastic fatigues and disintegrates, causing the collet shaft to stop, even if the motor is still running. The fix is about $5.00 --- two parts from Dremel. The 275 case is a **** shell that opens with the removal of six T-10 Torx screws.

I would go direct to Dremel.com or call them at 1-800-437-3635 and get the schematic and parts you need, I just checked and they have a parts diagram online that you can view. go to the section about manuals/literature and type in your model number. Good luck
