Why are tungsten-toothed saw blades used to cut chipboard and resin-glued boards?

In the furniture industry, tungsten-toothed saw blades—specifically those tipped with cemented tungsten carbide—are essential for cutting materials like chipboard and resin-glued boards due to their extreme durability and hardness.

These materials are notoriously abrasive, often containing glues and resins that cause standard high-speed steel blades to dull rapidly. Tungsten carbide, which approaches the hardness of a diamond, maintains a sharp cutting edge significantly longer under these demanding conditions. By utilizing a composite of tungsten carbide grains held in a cobalt binder, these blades can operate at much higher cutting speeds and withstand the wear caused by the dense, composite nature of engineered wood products.12
