Thanks Jason. If I’m reading the ARC chart correctly, there’s only a couple of the smallest ER32 collets that won’t close down a full 1.0mm. That did surprise me.

As Sonic wants to hold milling cutters, both systems will work equally well, except the MT3 collet makes it very hard to see what you are cutting under the head.
