*by M***K on Reviewed in the United States on March 19, 2016*

Needed to machine some polycarbonate and thought I'd try a bit like this to see if it actually helped reduce the heat without affecting cut quality.  It worked well but even better when cooking the chip with some airflow.  The bit is quality and should last for a long time.  May like to get the smaller sizes at some point.
