DRILLING IN WOOD
Holes in wood can be made with the same twist drill bits used for metal or with spade bits.
These bits should be sharp and should be pulled out frequently when drilling to clear chips
from the flutes.
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 sulfurized cutting oil or lard oil.
DRILLING IN MASONRY
Use carbide tipped masonry bits. Refer to Drilling section. Keep even force on the drill but
not so much that you crack the brittle material. A smooth, even flow of dust indicates the
proper drilling rate.
