Bandsaw Blades and Tension

Bandsaw blades and tension; tension required in order to consistently produce a more accurate and straight cut, especially when machining dense or thick materials. Each saw blade for each specific job will require its own form of tensioning. For example, a carbon blade requires a tension of around 15,000 – 20,000 psi. Bi-metal blades require a higher tension. Why do bandsaw blades require so much tension? Proper blade tension allows for greater beam strength, and all bandsaw blades — regardless of their width — require the same amount of tension for maximum beam strength. The tighter the blade is stretched, …
