Cutouts
Cutouts can be made with either of two methods A or B.
A) Boring a starting hole
For internal cutouts without a lead-in cut from an edge, pre-drill a starting
hole 12 mm or more in diameter. Insert the blade into this hole to start
your cut.
B) Plunge cutting
You need not bore a starting hole or make a lead-in cut if you carefully
do as follows.
(1) Tilt the tool up on the front edge of the base with the blade point
positioned just above the workpiece surface.
(2) Apply pressure to the tool so that the front edge of the base will not
move when you switch on the tool and gently lower the back end of
the tool slowly.
(3) As the blade pierces the workpiece, slowly lower the base of the
tool down onto the workpiece surface.
(4) Complete the cut in the normal manner.
Finishing edges
To trim edges or make dimensional adjustments, run the blade lightly along
the cut edges.
Metal cutting
Always use a suitable coolant (cutting oil) when cutting metal. Failure to do so
will cause significant blade wear. The underside of the workpiece can be
greased instead of using a coolant.
