I have spent some more time looking into easily available tool holders. The issue is that few suppliers have the 1010 left hand tools required by the Boxford 125 TCL lathe.

I'm not an expert on tooling, but here are the tool holder types that I'm considering at the moment:
- Left hand tools -
SCLCL1010H06 turning tool with CCMT0602 inserts
MGEHL1010-1.5 parting/grooving tool with MGMN150 inserts (The Boxford recommended ISCAR tool uses 1.6mm inserts but is hard to find "locally". The other easily available width is 2.0mm)
SEL1010H11 threading tool with 11ER inserts
S06K-SCLCL06 boring bar with CCMT0602 inserts. Alternatively S08K-SCLCL06 (which is most likely more similar to the Boxford recommended A08MSEUPL06)

- Right hand tool -
SCLCR1010 turning tool with CCMT0602 inserts

- Drills -
Centre drill
4 & 8mm twist drills or 5mm and 10mm twist drills (as specified by Boxford)

I'm considering two alternatives at the moment:
- buy all the suitable Glanze tool holders and the SGTFL 1010-1.6 ISCAR parting tool (if I can find that available with sane pricing/shipping).
- buy from one of the Aliexpress sellers that has all tool holder variants needed, although with unknown quality but low prices

The lathe is going to be used in a makerspace and I suspect that the tools and insert bits might not get all the TLC that they would want. In addition this is a huge learning experience for us so mistakes are likely. Due to this it might be wiser to go with the Aliexpress alternative and restock (possibly with better quality parts) when needed? However I don't want bad turning results due to using low quality tools.
