Mounting Annular Cutters
1. Place a pilot pin in the cutter at the shank end. Insert the cutter into the special
arbor.
2. Whenever mounting or removing cutters, always unplug the machine.
3. Lower the arbor.
4. Push up on the quick-release collar. Insert the cutter with pilot pin and turn until
the flat meets the locking pin. When the flat meets the locking pin, the collar will
snap down. Double check to ensure that it is fully locked.
6. Position the machine on a clean, dry, ferrous surface at least 7/16" thick. Switch
on the magnet.
7. Apply BruteLube wax at all times to annular cutters
to enhance the quality of cut and prolong the cutting
tool life.
8. Switch on the drill. Always proceed with caution at
the start of drilling operations.
When using RotoBrute annular cutters apply pressure
gradually at first until a depth of 1/8" is reached.
Normal cutting pressure can then be applied.
9. On completion of cut, withdraw the cutter from hole,
switch off the drill, then the magnet. Ensure the
magnet base is clear of chips. Locate the next hole
using the above procedures.
10. To remove the cutter, lower the arbor, push up on the quick-release collar and
remove the cutter.
General Operation
WARNING: Always ensure that the magnet is adhered properly to the workpiece
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.
BruteLube Wax should be used.
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. Therefore 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.
NOTE: Always ensure that the cutting tool is sharp. A dull cutter typically will have
finer and/or choppy shavings.
WARNING: ALWAYS clear chips when there is too much build-up. Excessive chip
build-up could result in a jammed cutter or other hazardous situation.
WARNING: The slug ejects at end of cut and is very hot. Always provide a method of
catching the slug, where the ejected slug may cause injury to people below.
CAUTION: Take extreme caution if attempting to cut half-circles or to stitch drill (drill
overlapping holes) with a tungsten carbide cutter. This may destroy the cutter.

Reversing of Changing the Position of the Handle
The handle is quick-release and adjustable to suit
different operating conditions.
If it is required to mount the handle on the
opposite side or to change its position, push the
Release Button in the center of the handle-hub
and remove. Press the Button and mount on the
opposite side or in the desired position.
L.E.D Work Light
The RB30 is equipped with the L.E.D WORK
LIGHT which is always on whenever the machine
is plugged in. This is useful when working in low
light conditions.
Carbon Brushes
The carbon brushes are a normal wear part and must
be replaced when they reach their wear limit.
Caution: Always replace the brushes as a pair.
To replace:
1. Remove the 4 screws and remove the motor tail
cover.
2. Using pliers rotate the brush spring out of the way
and slide the old carbon brush out of the brush holder.
3. Unscrew the screw to remove the brush lead. The
old carbon brush may now be lifted away.
4. To install a new brush, undertake the reverse of the
removal detailed above.
5. Replace the motor tail cover.
The brush design stops the machine before the
carbon brushes are finished and protects the motor.
In the event of the machine coming to a stop without
obvious reason - then check the brushes immediately.
