MOUNTING ANNULAR CUTTERS
CAUTION: Never use a cutting tool that is larger than the maximum rated capacity of the machine.
1. To insert an annular cutter, first insert the pilot pin into the
cutter. Then slide the cutter into the arbor, align the proper
flat with the locking screw(s) and tighten securely with the
supplied hex wrench.
CAUTION: Ensure that the locking screw is on a flat of the cutter
and not just against the rounded shank.
2. Ensure that the oil feed tap is on and coolant feeds properly by pushing the pilot pin. If it feeds too
quickly or slowly, adjust the tap accordingly. Keep the tap closed when not in use.
OPERATION-GENERAL
WARNING: Always ensure that the magnet is adhered properly to the work piece before beginning
drilling.
NOTE: If mounting to a curved surface beam, mount the machine parallel to the curve in the work
piece.
WARNING: Avoid operating at more than 90 degrees from horizontal. When drilling at such an angle
take precautions to prevent cutting coolant from entering the motor. Paste-type coolant should be
used.
CAUTION: Machine is equipped with a reversing switch. Always ensure that direction of rotation is
correct before operating. Operating in the wrong direction could result in damage to the cutter.
1. First fit tool into arbor and line up with intended center of cut. Then
switch magnet on.
2. Press green motor on button to start motor. Use the crank handle to feed
to work. Always use very light pressure when beginning the cut and just
as the tool is breaking through. The crank handle offers tremendous
leverage; so do not use too much force. Allow the cutting tool to
determine the pace. With experience, the operator will be able to
determine the best pace to feed to the work. There should be some
degree of audible slowing of the motor but not bogging in the cut.
Correct cutting speed with a properly sharp annular cutter will produce
long unbroken chips, which produce a “bird’s” nest. shaped bundle of
chips around the cut.
