Quarter inch collet?

I was just reading that the CNC tool head will accept bits up to a quarter inch - where can you get the spring collet for allowing this because the one you get with it will not fit a quarter inch bit and I can’t seem to find it for sale on the Snapmaker Home page either? Thank you

Just search amazon or ebay for er11 collets.
You can get a set of various sizes for fairly cheap.

Thank you for that info - I will do that for sure.
