I don't have one, should consider it. Hard material would grind through
while a saw requires M42 or magic to cut.

Some just work hardens as you saw.

A chop saw is fairly inexpensive at HF, blades are cheap at the same
place or on Ebay. And its a ****load faster than your recip saw. Much
much faster!

The single biggest issue with a chop saw..put a piece of masonite,
plywood or sheet steel on the wall behind the saw so the trail of
sparks doesnt catch stuff on fire.


I've got a band saw, chop saw, cold saw, and an OLD power hacksaw. Each
has it's strong and weak points. The power hack saw does have one unique
quality, on a long cut the even rhythm has made me sleepy!!
