An ER-20 Collet Holder Plate
I needed a simple way to organize my metric ER-20 collet set. Initially, I tossed them in a pencil box. That did keep them from rolling away but certainly was not a satisfying solution. Could have CNC’d a plate with tapered holes but that really didn’t interest me. I liked the idea of a tapered hole to help retain each collet but didn’t want to put forth a lot of effort. Then the trick hit me – use a step drill!

Rick, using a step drill is a brilliant way to make the holes and will consider this next time I make another ER collet rack. I took the easy way out when I made my ER16 collet rack out of oak and just drilled two holes (small bottom hole to catch the narrow end and a larger hole to catch the top edge) with Forstner bits to accommodate the collet tapers. I like your method better. Thanks, Paul
