In these clips, 10mm thick steel is cut with a water jet machine.

As a first timer it was amazing to see.

The water is pumped through a tungsten carbide jet, under enormous pressure.  The water carries garnet dust, which does the actual cutting.

The steel is 10mm thick, but this machine will cut through 200mm thick steel!  It will cut wood, carpet, granite, marble, any metal, in fact any material except diamond and some glass.

The cut is accurate to within 0.1mm.  The kerf is 1mm.  The angle of divergence away from the vertical is approx 1 degree.
