Milwaukee Tool says its Extreme Metal Band Saw Blades cut two times faster and last three times longer than standard blades in thick and thin metals. When it comes to band saw blades, the biggest user frustration is the frequency of changing out the blade. Milwaukee’s new blades solve this frustration through a combination of enhanced high-speed steel and a variable TPI tooth design, making two times faster cuts in thick metals and achieving three times longer life in stainless steel. These features also unlock the ability to cut through cast iron.
