PLASTICS jigsaw blades

Blades for plastic, acrylic and composite panel. Plastic is the awkward material for a jigsaw: cut too fast and friction melts it, so the kerf welds shut behind the blade. These are ground and pitched to clear the chip rather than smear it. A bi-metal blade covers general plastics; the carbide-tipped blade handles abrasive composites and mineral-filled sheet that would blunt steel in a metre.
