Carmen, I am having the same issue, must be I over tightened when I first set it up. ---

Used a drill slightly smaller than the set screw. Drilled hole through and once it got through I was able to use a screw extractor and/or slightly larger screwdriver to spin the remaining pieces of the set screw out. ---

Hey Mike, > [@Bumpski](#): > > Making a sign with a patch that had very small words in the middle of it. With the makita I could read it easily and with the larger spindle I can not really make out the words. On the entire job this was the only issue I had. Overall it was much smoother and quieter but I would like to figure out what is causing this. if you really loose detail after having switched from the trim router to a spindle (which mostly have less than 5 µm runout and are able to hold their speed strictly, regardless of load (what a trim router is not able to), after thinking about it for a while, I came to the thought, is it possible that you made a mistake when mounting the collet? ER collets are not mounted the way a trim router collet is mounted. Most people put the collet into the axle of the spindle and then they put the collet nut over it. **That is definetely wrong!** An ER collet has a groove that goes all the way around near the top of the collet. The corresponding **collet nut** of an ER collet has an excentric extractor ring or offset lip inside. It is absolutely mandatory to fully engage (clip in) the collet inside the nut **before** you tighten it onto the holder, as shown at [this moment of the video “ER Collets | 5 Things to Know for Beginners”](https://www.youtube.com/watch?v=R0tJorTM0BE&t=153s).

Great advice on mounting ER collets. This is something that can be easily missed and cause a mess. If you make this mistake on a metal working machine (metal lathe or mill), you will find out pretty quick that you’ve made a mess. Ask me how I know! ---

I had found this video interesting wrt tool holders, collets, and collet nuts… [Haas Automation Tip of the Day](https://www.youtube.com/watch?v=WKikm6cQKh0) They have great information in general on a variety of topics, metal focused, however often applicable. ---

In a geeky sort of way quite fascinating (although I’ll never admit that to the family) ---

Just converted to the 80mm base. The two set screws came right out. Received my JW50 in early December 2021 ---

I think also here that Bosch Rexroth is highly configurable and will give you a great deal.
