A "hot saw" is a specialized cutting tool used primarily in the logging industry. It features a powerful engine and a large circular blade that can cut through thick tree trunks quickly and efficiently. The saw operates at high temperatures, which helps to reduce friction and improve cutting performance. Hot saws are often mounted on a tracked or wheeled chassis, allowing for mobility in rugged terrain. They are commonly used in conjunction with other logging equipment, such as feller bunchers and skidders, to streamline the process of harvesting timber. Safety measures are essential when operating a hot saw due to its size and power.
