👉Incorrect TPI increases cutting load and can lead to weld failure — see why blades break at the weld
Blade type selection (M42, PM51 or carbide) is equally important
👉—see our full guide to metal cutting bandsaw blades for steel.
Using the correct tooth pitch is one of the easiest ways to improve blade life and reduce 👉 bandsaw blade cost per cut.
