These hacksaw blades (12 inch x 18 TPI,24TPI,32TPI) are the virtually unbreakable and shatterproof bi-metal blades with precision-ground teeth for all kinds of metal sawing. With a blade back of strong, flexible spring steel and a tooth line in high-alloyed super high speed steel, this blade is guaranteed to keep its sharpness for a long time. The new Sandflex blade combines extreme cutting performance and wear resistance with a high degree of flexibility and is vastly superior to all-hard high speed blades or conventional, flexible blades.
