Occasionally, I need to drill blind holes in a completed project using a Forstner or multi-spur bit to install round magnets as cabinet catches. The problem is that it’s tricky to guide a bit like this freehand. I’ve found that the solution is to use a guide block that I first bore on the drill press using the desired bit. Make the block long enough to allow clamping it to your cabinet case, panel, or other project part. When laying out the hole, extend the centerlines beyond the perimeter of the hole diameter to help you position the block in use by aligning it with crosshairs on the workpiece. After boring through the block, clamp it in place and use the same bit to drill your blind hole freehand.
