Insertion of pilot pin
• The pilot pin is used to both centre the cutter and to eject
the slug on completion of the cut. It has a flat side to allow
coolant to run down to reach the centre of the cut where the
heat is greatest. Slide the pin through the hole in the centre
of the cutter shank
.
F
ITTING THE CUTTER
• With a standard arbor, two grub screws secure the cutter in
the arbor. The cutter shank has two flats that must be aligned
with the grub screws in the arbor (fig. 3). Insert the cutter shank
into the arbor. The screws must be tightened evenly (using
the 5mm Allen key supplied) so that the cutter is prevented
from moving (fig. 4).
• Machines fitted with the Quickhitch™ arbor will accept
any cutter with a 19mm diameter shank having one or more
flats.
To fit a cutter, align it below the Quickhitch™ and twist the
arbor sleeve clockwise against its spring and hold, Fig. 5.
Insert shank of cutter into arbor, push it home and release
the sleeve, Fig.6.
Twist the cutter in the arbor to ensure the flat is engaged in
the locking mechanism, Fig.7.
Turn the sleeve fully anti-clockwise to complete the locking
operation’ Fig.8.
To remove the cutter, simply twist the sleeve clockwise
against the spring, the cutter will be ejected.
Mark the position of the hole
• Make sure the workpiece is clean and flat and position the
machine with the pilot over the centre of the hole to be cut.
FIT THE SAFETY STRAP.
Applying Coolant
• Cutting oil ensures longer cutter life and enables the slug
to be ejected cleanly. A 500 ml bottle is included with
every machine.
• On machines with a coolant system, oil will be automatically
delivered to the cutter when the cut commences
• On machines with an internal oil arbor, fill the reservoir in
the arbor through the small holes at the top.
• When cutting on vertical surfaces or upside down, cutting
paste, gel or foam is recommended. It is best applied inside
the cutter before drilling.
