The collet nut on my Dewalt 625 plunge router got cross threaded on the armature; armature threads are messed up some, collet nut threads are fine. Anyone ever use a die to fix something like this? A new armature is over a hundred bucks, I don’t use this router very often. Would anyone know what size these threads are? Thanks.

Well that’s a big pot of suckiness. I don’t know the size, but I know that bigger dies are harder to find than normal small bolt sizes. You might try and find a thread chaser or restoring file .

Good Luck.

Found this link from another forum for the same problem:

The thread may be metric, you an use a caliper to measure the pitch. It is a fine thread and a die will be pricy. Try thread file to file away the damaged ares between the threads.

I would just use some needle files.

I’d file it. Easier to do than you think. You may want to
buy some little files if you don’t have them. They come
in useful in other ways. I am sure that’s a metric tool
as it’s from Italy/Switzerland.

If it is just a small area, a small triangular file can do it, but if it is a larger area, I have always had better luck
with the thread files, they tend to set in the tool box a lot, but when needed, they are great to have.
