I'll answer last question first. They might be cracking because they are in a bind and when turned on or inserted on the shaft there is too much pressure. Make sure the shafts are free of any debris from the original coupling, also check the bearings for wear or being so tight that they twist the coupling. Everything should move freely. And second I would recommend calling Dremel direct at 1-800-437-3635 for replacement parts. Hope this helps.

I need part # 2615294309 coupler for a 395 Dremel tool


I had the same problem - couldn't get the part (plastic coupler between the spline drive shafts). I purchased a waterproof **** Splice (GB-AMT-5126 12-10 gauge -- used for electrical wire splicing -- got it at Home Depot). Clipped off about 3/8" on each end with diagonal cutters and attached it to the shafts. The steel ring in the middle of the **** Splice connector provides good structural support to the connection. Works like a charm. Plus with a pack of 4 connectors, I have 3 in reserve.

Stripped plastic coupler on output shaft of Dremel model 277


I'm guessing, but I think that the Sears tool uses the same flexible coupling. If you go to www.searspartsdirect.com and put in the model 572610031, you can look at the diagram and decide for yourself. I think the part costs $2.57. If it's the right one, I'd order two or three for the future.
Hope this helps.

Nylon Coupler cracks when installing


I would call Dremel direct at 1-800-437-3635 and order them. They also have a tech line, but I would think that they are in a bind when installing and cracking. Look at the bearings to make sure they are not tight or completely locked up. Let me know if I can help further

Coupling broke


I have a Dremel 395 Type 3. Motor works fine, shaft doesn't turn. Took it apart to find that the white plastic or nylon flex coupling on the shaft had crumbled and the spline driver, which fits directly over the motor end of the shaft was somewhat worn. I emailed Dremel and got an overnight reply listing the 2 parts I need and the cost: Coupling is $1.00 and the driver is $1.25. Placed order by phone: 1-800-437-3635. I ordered 2 of each in case future replacement is needed. Total bill came to $7.27 including Florida tax and shipping. Can't beat that. They said it would be in the mail by tonight. (Flex coupling number is 2615294309; spline driver is 2615294308.)
