Drilling in wood
When drilling in wood, best results are obtained with wood drills equipped with
a
guide
screw. The guide screw makes drilling easier by pulling the bit into the workpiece.
To prevent the bit from slipping when starting
a
hole, make an indentation with
a
center-
punch and hammer
at
the point to be drilled. Place the point of the bit in the indenta-
tion and start drilling.
Use
a
cutting lubricant when drilling metals. The exceptions are iron and brass which
should be drilled dry.
