I have bought old cabinets which I would like to hang on a brick wall. I have marked the spots on the wall, but I find it very difficult to drill precisely, because the drill bit follows a path of least resistance.

What are the techniques and tools required to drill a hole with less than one millimeter between the actual hole and the mark ?

The most important part is to start off in the correct location. Once you have started the hole it's relatively easy to keep straight if you take it slowly and have a steady hand.

If your drill has a variable speed - either via a selector switch or by varying the pressure on the trigger - use the lowest speed possible to start the hole. A drill that uses trigger pressure is best as you can start with the drill bit on the mark and then gradually increase the speed. This prevents the bit skidding on the surface.

Once you have the first few millimetres drilled bring the drill up to full speed. You will need to push but don't use your full weight on the drill.

You might find it useful to have someone else watch so they can tell you if you aren't holding the drill perpendicular to the wall.

The easiest way to drill brick without the bit moving off the mark is to use a nail/center punch/awl/nail set etc.. to make an indentation on your mark. Take one of the above objects, and place the point on the mark on the brick and tap it with a hammer, this will make a little indentation on the brick that will hold the drill bit in place until it digs into the brick.

This trick also works on tile. The key is not to hit the object into the brick too hard to prevent the brick/tile from damage.
