Power
hacksaws are exactly what it sounds like. They are hacksaws which
are electrically powered and built to cut through large crossections
of steel and other metals. Power hacksaws usually consist of a a
motorised hacksaw blade - which only cuts on the backstroke, a vice
to hold the metal which is being cut, and a cooling flow of water
(or coolant liquid) which helps keep hacksaw blade cool while it
is being cut.
