QC30 / NMTB-30 Collet Chuck / Tool Holder DA300

Description

**Listing is for ONE collet chuck No collets, tools or rack included. I only have DA300 (small diameter collets) available.
These are Erickson QC-30 chunks that will fit the quick change 30 spindle commonly used on Bridgeport BOSS machines. These are also backwards compatible with an NMTB-30 spindle with drawbar. However, NMTB-30 tooling likely will not fit in the QC30 spindles (flange is generally too thick) especially the chinese holders, so if you have a QC30 spindle this is what you need for it to work correctly.
Removed from service in good condition.
