Erbaurer er 2100 is probably a Ryobi rebranded Erbaurer by Kingfisher International Products LimitedHello, I’ve tried everything to get my router bit out of the collet but it won’t come out. I’m in desperate need of a new collet nut part except I can’t find any spare part for this brand. It’s a erbaurer er 2100, requires 1/2mm shank. If someone could help me find somewhere where I could purchase would I would gravely appreciate that
Thanks xav
Measure the diameter of the shaft. If it is 20mm, you should be able to use a Ryobi Collet nut and collet.

I got this pic from Aliexpress search for Ryobi collet.
