The Kreg Drilling Guide makes it easy to create perfectly straight holes without using a drill press. You can get precisely positioned holes with just a hand drill. Featuring six hardened steel drill guides���from 1/8' to 1/2'���that do the work of holding your drill in position for you. The Guide features an ergonomic design and Kreg GripMaxx™ material that ensures it stays in place as you use it, so your drill bit won���t wander off your mark as you start the hole. The Drilling Guide also automatically centers on the edge of 3/4'-wide and 1/2'-wide boards and plywood, so you can drill holes that are perpendicular to the edge and perfectly centered. Use the Drill Guide for all kinds of tasks ��� whether you need a hole for driving a screw, mounting hardware, helping create a dowel joint, and much more.
