Why are they unsafe?

Wait until the first time a bunch of swarf suddenly wraps around the
tool, work and chuck and start whipping snot out of the guard. If you
insist on using one make sure it is solidly mounted and you are always
using chip breaker tooling.

Aside from some damage to the guard, this actually sounds like an
advantage to me. If that long chip didn't hit the guard, it would hit
something else, like me.


Would love to hear your report in about 6 months time.

Sure.

Actually, with the coolant I've been getting very long chips when
parting 1018 off. If under power feed, often it's one big chip, if I
don't interfere. These chips are not that heavy, but can be quite
sharp-edged. And I have already had cases of flailing-nest syndrome.
