6K Collet Racks 6K collets like that used in a 10k South Bend lathe fit nicely in my DA180 collet racks.  Unlike the 6K's, DA180 collets go up to 3/4".  You can use the extra pockets over 5/8" for your extra collets or use the blank racks where you can write in your sizes. If you intend on mounting the racks on the wall it will work great as-is. However if you would like it to be a bench top (or drawer) rack you will need to order the side legs at the bottom of the 5C page.
