Care in Drilling
Twist drills are brittle and will break if enough bending stress is applied.
To avoid stress on the drill bit, try extending your index finger along the
side of the drill-housing with your middle finger on the trigger. Remember
— guide the tool, don't force it! Should the tool become overheated,
run it free of any load. The drill will cool faster by running it without load.
Drilling in Metal
Use a cutting lubricant when drilling metals. The exceptions are cast iron
and brass which should be drilled dry. The cutting lubricants that work
best are sulphurized cutting oil or lard oil; bacon grease will also serve
the purpose. Aluminum is best drilled with turpentine or kerosene.
Drilling in Wood
Holes in wood can be made with the same twist drills used for metal.
These bits may overheat unless pulled out frequently to clear chips from
the flutes. For larger holes, use Power Drill Wood Bits with a shank size
that will fit your drill's chuck. Work that is apt to splinter should be
backed up with a block of wood. Let up on the pressure just before the
tip cuts through, this will give a good clean hole. Always leave the drill
running when pulling it back out of a drilled hole, this prevents jamming.
