For drilling perfectly centered holes in broken studs, this guide system utilizes an anchor rail with a 6" (15.2 cm) reach to secure the tool to any open hole near the damaged fastener. It includes four bushings for 6 mm, 8 mm, 10 mm, and 12 mm stud sizes, as well as four progressive drilling guides ranging from 1/16 to 5/32" (1.6 to 4 mm). The kit comes with a vinyl storage pouch and instructions for use.
