Unlike the lifetime warranty we offer on the 3" bits, the Duo Star bit does not come with a warranty. This is a luxury tool for setters. Due to the machining of the tip, it will have a shorter lifespan than a standard bit. Setters still find the duo star bit to be worth the extra money with the time savings it provides.
