face=sans-serif size=2>The proper bandsaw blade for composites does not have
any teeth on it at all. The blade consists of a coating of tungsten
carbide bits like rough sandpaper grit adhered to the leading edge of the
band. The blade cuts by abrasion and will break before it wears out. Any blade
with teeth is bad for composites as it will dull and the teeth can grab and
delaminate the sustrate or your bond to the honeycomb.<BR></FONT><BR><FONT
