Straight-Up Drill Guide - To bore a perfectly perpendicular hole, you need either a drill press or a couple of scraps of wood screwed together. The corner created by the scraps will steer the bit straight in every time. But if you’re looking for an excuse to buy a drill press, forget you ever saw this tip.
MAKE A JIG BOARD OF YOUR OWN ~ To make one, draw a 1⁄2-inch grid on the surface of a flat 6-by-12-inch piece of wood. Where lines intersect, drill 3⁄8-inch-deep holes with a 7⁄64-inch drill bit. To keep their depth uniform, mark the drill bit with a piece of tape. Make patterns by slipping 2-inch 6d finish nails into the holes. Wrap wire around the nails, then slip the pattern off the jig.
The chart below shows which screw and setting you should choose based on your material thickness. By choosing the correct Kreg screw and Kreg Jig setting, you will drill perfect pocket holes every time, ensuring project success.
