The strong, high performance triple chip Tungsten Carbide Tipped (CT) Hole Saw offers a longer blade life when cutting difficult and abrasive materials. A cost effective solution for cutting through nail-embedded wood, or virtually any wood and metal combination, reinforced concrete and fibreglass. This saw is particularly suitable where there is a requirement for a high quality surface finish on the entry and exit hole and provides a smooth cut when cutting traditional lath and plaster.
