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 (1/2”) 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 sur-
face.
(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.
