I think you are confusing Plexiglas (arcylic) and Leaxan (polycarbonate).
Polycarbonate machines and drills much better than Plexiglas. Arcylic
shatters and cracks when it is worked with including drilling bending and
milling. Polycarbonate on the other hand is much nicer to work with. It will
not shatter like Arcylic (It is used for bullet proof windows) when
machined. It can even be bend in a brake to over 90 degrees without braking.
If one is doing a lot of drilling or machining USE LEXAN.

Hi All,

  I've used both polycarbonate and acrylic, and the arcylic machines *much*
easier than the polycarbonate in most cases.  The acrylic usually makes
clean cuts and smooth swarf, whereas the polycarbonate was prone to
chipping badly and breaking off in little bits instead of
cutting.  Drilling the polycarbonate was also a pain in the butt, as I had
bad problems of it cracking outwards from the hole as the drill punched
through the backside, even when drilling slow.  I may have had crap
polycarb, so I can't say that all does that, but I had 3 different
thicknesses do the same thing.

  Hope it helps!
