General Hints for drilling in all materials
Always use sharp drill bits.
Mark the place where you would like the hole to be drilled.
Commence with a slow speed to start the hole (see section “Speed Control”
for directions on how to do this).
Reduce your pressure on the drill when the drill bit is about to break through
the material.
metal drilling
Support thin material with a piece of scrap wood.
Use a centre punch to mark the position of the hole.
If drilling a large hole, use a small size drill bit first to establish a pilot hole then
use the required large size drill bit.
Use only HSS (high speed steel) drill bits or those recommended for metal use.
When drilling into iron or steel, use a cooling lubricant such as thin oil. With
aluminium, use turpentine or paraffin. With brass, copper and cast iron, use no
lubricant but withdraw the drill regularly to assist cooling.
