recommendation was about wearing a mask while cutting jump rings
with either the Koil Kutter or Jump Ringer? Although it seems that
most of the metal dust goes down, I wasn't sure if there are any
health issues concerning the dust.
i don’t know how the machines work, but you did say dust, didn’t
you??? if there is metal dust exaust it off or wear a light dust
filtered respirator called a disposable half-mask don’t breathe it
not in the least
