How can I drill holes less than 1" from a wall?
Various methods, the most accessible of which tends to be a long drill bit - 12-18&quot; long, allowing the chuck to get out of the way.
If you don't flex the bit, the slight angle (not quite perpendicular) is generally not a problem, but under the guise of &quot;aircraft drills&quot; there are very long bits with short flutes and a long smooth shank that flex sufficiently that you can get them perpendicular, if needed.
A physically smaller drill chuck is the more obvious but generally less accessible method.
