opening blocked cooling holes in Stage 1 gas turbine blades
hi all,
anyone can share the way of opening blocked cooling holes
in turbine blades? usually, I am using air grinder with small filler wire
to remove blocked cooling holes ,which has blocked by mud or while grit blasting.

please let me know is there any machine or special method

Cheers, krishz
