Kreg
The Kreg Drilling Guide enables you to create straight, accurate holes without a drill press. Easily fitting into any pocket, the 6 hardened-steel guides range from 1/8" to 1/2" and hold the drill bit perpendicular while you use just a hand drill. Alignment marks help you line up perfectly every time and the GripMaxx™ surface keeps everything in place. Ergonomic design makes it comfortable use time after time, plus it automatically centers on edges of 1/2" and 3/4" wide boards. Works with twist and brad point drill bits.
Capacity: 1/8", 3/16", 1/4", 5/16", 3/8", 1/2" drill bits.
