I picked up a used Bridgeport Series 1 CNC that I am converting to Mach 3. Anyway, it has the 1/4 turn QC spindle on it and I am having difficulty finding suppliers for the tool holders. So I thought I would as the forum members for input.

are they 30's or the universals kwik switch? both should be found at MSC

Gus, Thanks for the reply. The spanner wrench for it says "erickson no. 30 quick change". Is it true that an NMTB30 will interchange with this or am I limited to using QC30?

some NMTB30 tooling will work. I know bison NMTB30 tooling works fine.

I found a company in CT called Somma tool that still advertises QC30 tooling in their catalog. Leadtimes are between 1-3 weeks. Here is the link:
