Save Time, Save Energy...Set Better. With the Duo Star Bit you always have the right bit at the right time for installing climbing holds. This 2-in-1 bit fits both your bolt and the classic T25 set-screw, meaning with just this one bit you can bolt and set screw that hold on the wall without ever fussing with switching bits in your drill. Setting simply made better..
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.
