With a 25% smaller hole diameter, the Micro-Pocket™ Drill Guide lets you create compact, low-profile pocket holes in the same Kreg Joinery applications where you'd use standard Kreg pocket holes, and in a variety of other applications, too. You also have the ability to tackle smaller projects, thinner stock, and tighter repairs where standard pocket holes simply can’t go. Choose Your Jig Compatible with the Kreg Jig® K3, K4, K4MS, and K5. Features black color to differentiate from the standard Kreg Drill Guide. Endless Applications A 25% smaller pocket hole works great in virtually every application where you’d use standard Kreg pocket holes. And because it removes less material, drill strokes are faster and easier. Perfect for 1/2" Stock Screw heads seat well below the material surface in thin stock, making the Micro-Pocket™ Drill Guide perfect for creating fully-pluggable pocket holes in 1/2" (12mm) thick material like drawer boxes. Perfect for Narrow Stock Reduced width lets you drill two holes in extremely narrow stock, down to 1" wide, creating a much stronger joint in narrow pieces.
