This unique bit works with the Micro-Pocket™ Drill Guide to create a 25% smaller pocket hole (15/16"-long). Micro-Pocket™ holes work great in virtually every application where you’d use standard pocket holes, and are especially good for 1/2" (12mm) thick material and narrow stock, down to 1" (25mm) wide. Because the bit removes less material, drill strokes are faster and easier. For Use With: Compatible with the Kreg Jig® K3, K4, K4MS, and K5, when being used with the Micro-Pocket™ Drill Guide. Also compatible with the Foreman Pocket-Hole Machine (Item# DB210).
