4hp Hiteco specs

What size wrenches do I need for the spindle shaft and the ER20 collet nut? I have misplaced mine and what I’m using now isn’t the correct size and it’s very lose but gets the job done😆

A 20mm and a 30mm will take care of that

Awesome thanks !!! My goal is to find some nice tools to work with my Hiteco.

Do you know anything about collet nuts? All I have is the one that came with the spindle. I would like to purchase one of those ER20 Nuts that you see with the cuts around it that use the matching wrench. these nuts appear to be machined very well
