At what speed must an electrical saw blade be operating before contacting the material it is cutting?

For an electrical saw blade to efficiently cut through material, it needs to operate at full speed before making contact. This allows the blade to achieve the necessary rotational inertia and cutting performance required for effective material removal. The sharp edges of the blade are designed to slice through materials when they are moving at optimal speeds, ensuring a clean and efficient cut. Slower speeds may lead to increased friction, potential binding, or even damage to the blade and the material being cut.

Choosing to operate at half speed or a quarter speed would not provide adequate cutting efficiency, as the blade would struggle to penetrate the material effectively, leading to suboptimal results. While variable speed settings can be beneficial for certain materials or specific tasks, the question specifically addresses the condition of making contact with the material, which requires full speed for optimal cutting capability.
