Drilling operation
First, turn the adjusting ring so that the pointer on the tool body points to the
8
marking.
Then proceed as follows.
*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 indentation
and start drilling.
Use a cutting lubricant when drilling metals. The exceptions are iron and brass which
should be drilled dry.
