Tips for using a drill
Safety
Always check for wiring and pipes before drilling into a wall.
Wear safety glasses and hearing protection, particularly when hammering,
drilling or in confined spaces.
Screwdriving
If you're not sure what clutch setting to use, start with a low torque setting
and gradually increase it until you get the desired result
(the clutch should slip just when the screw is fully sunk).
Drilling Through Timber
Timber can usually be drilled at high speed (high gear) unless you're using
a particularly wide bit, say 13mm or more, or if the timber is especially hard.
To avoid splintering the other side of the timber as the drill bit breaks through,
clamp stiff cardboard to the back of the timber. Don't force the drill;
apply moderate pressure to let the drill work at its own rate,
and ease off the pressure as the bit is about to break through.
Drilling Through Steel
Use a bit rated for steel and set the drill to a slow speed (low gear).
A little oil on the spot to be drilled helps lubricate and cool the drill bit.
Clamping a piece of timber under the steel helps you achieve a clean exit hole and
also protects your workbench.
