Hold or clamp a framing
square or combination square on the work surface just beyond the hole. Use
it to line up the shank of the bit with the square's edge. |
Use a portable drill press
that mounts the drill to a carriage that slides up and down on two guide
rods. The press's base plate sits flat on the work surface, allowing you
to drill perfect holes every time. |
Some drills come with
small bubble level vials built into the rear section of the body. Aligning
the bubbles with their centre marks ensures the drill bit is plumb. |
For dowel joints, the best
solution is to use a dowel jig. This jig ensures that the hole you are
drilling is at the correct angle to the wood. |
