Primalloy™
High-performance Starrett bi-metal band saw blade with Extended Life (EXT) treatment.
Primalloy™ has a special high-speed steel cutting edge with positive rake geometry and ground teeth. Its back receives the Extended Life (EXT) Treatment, which extends blade life against fatigue.
Its high cobalt and vanadium content delivers high production, greater wear and heat resistance, and good penetration in hard materials, with excellent cost per cut.
