OPERATION
Drilling operation
Drilling in wood
When drilling in wood, the 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.
Drilling in metal
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
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 performance and shorten the service life of the
tool.
There is a tremendous twisting force exerted on
•
the tool/bit at the time of hole breakthrough. Hold
the tool firmly and exert care when the bit begins to
break through the workpiece.

Avoid drilling in material that you suspect contains

hidden nails or other things that may cause the bit
to bind or break.
