General description This is a bi-metal HSS hole saw designed for cutting through various materials with precision and durability. Its unique tooth geometry and tooth engagement ensure that each tooth works independently during cutting, reducing vibrations and wear. This results in cleaner cuts and longer tool life, especially when working with tough materials like stainless steel. The saw provides excellent performance in both wood and metal applications.
