rotozip spindle?

Hello, new build here. I went to Home Depot today to grab the conduit and Dewalt and found out they no longer supply the Dewalt 660 in store, same for Lowes.

Before I order one, I noticed that I have already got a 30,000 rpm spindle: Rotozip.

Anyone have any experience using these on MPCNC? The only discernible difference I see is the Rotozip has 5.5 volt vs Dewalt 5 volt and the Rotozip has a third 5/32" collet

Would like to hear any thoughts regarding this spindle. Thanks in advance.
