I bought a Hitachi M12VC Router. It came with 2 standard collets 1/2" and 1/4". I then bought a set of ER20 collets off of Ebay, thinking everything was standard. So I bought a nut and wrench from Maritool. Not the same either. They were kind enough to take it back. Then bought a nut, wrench and a ER20 1/8" collet specifically for the Hitachi from K2CNC. Works great, but not compatible with the collet set. K2cnc nut was from Think and Tinker. So I now have a 1/8" w/nut, 1/4" w/nut, 1/2" w/nut. Any one know where I can get different size collets for this router? Thanks in advance. Mike
