Hi, I have recently built my first CNC router, LEAD 1010. For the router, I went with a Dewalt D26204K. The included collet accepts only 8mm bits but I would like to insert some 3.5mm, 4mm and 6mm bits. I would therefore think that I need an aftermarket ER chuck and collet(s). I have tried to purchase an ER8 but that was too small. Then I bought an ER16 but that was too big... So that was a bit of money down the drain... My question is: will an ER11 chuck fit? Or do any of you have a recommendation for what to use? Preferably something that can be shipped from EU og Asia. Thanks in advance!
