We have a wide variety of ER11 and ER20 collets for woodworking, and ER20's are what you would need for the ISO 20 Tool Holder
These collets have a .0004" / ..01mm runout and are available in many sizes.
Learn more about how ER collets work by checking out our KB: https://support.pwncnc.com/kb/article/253-er-collets-a-how-to/
Note: These collets are NOT compatible with Makita routers. Carbide3d does sell a Makita-clone which does support our ER11 collets... but in general Makitas use a proprietary collet system that is not compatible with the collets we sell.
Filled the need perfectly
The collets were on my son’s Christmas list. He was happy with them.
Since using these i have less tool marks and super clean cuts
Replaced the stock collet on my Makita Router. Bit stays put and no drops. Did a 3 hour carve using 3 bits with no issues. Releases bit after carve reliably.
