This is a replacement blade for the 4012 hacksaw, which features a heavy-duty cast aluminum frame and steel crossbar, giving you the perfect balance of a lightweight tool with super strength. The 4012 hacksaw's rugged frame can tension a blade to 30,000 PSI, which is about twice that of ordinary frames. The replacement blade features shatter-resistant bi-metal construction which allows the blade to bend and flex without snapping. The Tuff Tooth design eliminates tooth strippage for increased durability.
