When assembling a workbench in my garage, I needed a device for precise positioning of a pendicular drill bit. There was no time to look for a similar device for your old drill somewhere, and it's not a fact that it will fit 100%. Nothing prevented me from creating such a device for my drill myself. Yes, there are not enough springs, I have already ordered them on Aliexpress. I am sharing my developments with you.
