OPERATION Drillingoperation
Drillingin wood
When drilling in wood, the best results are obtained with
wood drills equipped with a guide screw. The guide screw
makesdrilling easier by pulling the bit into the workpiece.
Drillingin metal
Toprevent the bit from slip ping when starting a hole, make
an indentation with a center-punch and hammer at the point
to be drilled. Place the point of thebit in the indentation and
start drilling.
Use a cutting lubricant when drilling metals. The exceptions
are iron and brass which should be drilled dry.
CAUTION:
Pressing excessively on the tool will not speed up the
drilling. In fact, this excessive pressure will only serve to
damage the tip of your bit, decrease the tool
performanceand shorten the service life of the tool.

and exert care when the bit begins to break through the

bind or break.
