Redstripe power hacksaw blades are fully hardened molybdenum high speed steel. These are the ideal blades for long wear life and top performance in sawing a wide range of materials, including stainless and other tough-to-cut alloy steels. These solid high speed steel blades will withstand heavier feed pressures for faster cutting better than other types of hacksaw blades. Blades can withstand heavier feed pressures and provide faster cut rates than blades made from composite designs. Blades will effectively cut tough alloys such as stainless steels.
