Save Time, Save Energy… Set Better.
With the Duo Star Bit from Sendgineering you always have the right bit at the right time. This 2-in-1 bit fits both a standard 5/16″ bolt and the classic T25 screw, meaning with just this one bit you can bolt and set screw that hold on the wall without ever fussing with another bit.
Setting simply made better.
Unlike the lifetime warranty we offer on the 3″ bits, the Duo Star bit does not come with a warranty.
