MAGNETIC DRILL SAFETYAlways carry the power tool properly with the carrying han-
Safety Strap
The electro-magnet base on this power tool can release if there is a interruption in power
supply or electrical malfunction.
The safety strap provided should be used at all times to prevent the power tool from
falling in the event of power failure or electrical malfunction, possibly causing injury.
The safety ratchet strap should be attached to the fixing points provided and checked for
security before commencing any drilling operation.
Magnetic Adhesion
The magnets strength depends on the thickness and condition of the work piece material.
Always ensure that the work piece has a minimum thickness of 12mm or 1/2” to ensure
there is adequate magnetic adhesion.
If the work piece is less than 12mm or 1/2” then a piece of steel plate 12mm or 1/2” in
thickness and larger than the magnet footprint must be inserted between the magnet and
work piece to supplement the magnetic adhesion.
The surface on which the magnet is placed should be clean, flat and clear from debris or
rust. The base of the magnet should be inspected to ensure it is also clean flat and clear
of debris.
Always check the magnet is securely adhered to the work piece before commencing any
drill operations.
Do not use other appliances on the same power receptacle, any variation in voltage
cause by other appliances could result in the magnet releasing. Always us the tool on its
own power receptacle.
This power tool can be used on a vertical surface or upside down provided there is
sufficient magnetic adhesion, extra care should be taken when drilling vertically or upside
down . When using the machine vertically or upside down it is possible hot and sharp
swarf or chips may fall. Always wear appropriate personal protective equipment
When Cutting
When using coolant of lubricants, ensure coolants and lubricants do not enter the drill
units ventilation/cooling openings.
When using annular cutters ensure that the slug ejected at the end of the cut will not
endanger anyone in the vicinity, if working at height some form of collection device for the
ejected slug may be necessary.
Care should be taken with the ejected slug, this will be both hot and sharp, gloves should
be worn when handling the slug.

The guard has approximately 50mm of travel
which is adequate standard length cutters.
The guard should be adjusted so it is able to
slide with light pressure.
11 PB32 - Revised 120810
MOUNTING CUTTERS INTO THE ARBOR
The holder for the cutting tool is known as the
arbor. The arbor is designed to accept
Powerbor 3/4” Weldon shank annular cutters.
The Powerbor annular cutters normally have
two flats disposed at 90°to each other.
To mount the cutter.
First ensure the ejector pin is in place.
Align the two flats with the two fixing screws.
Push the cutter up into the arbor until it stops.
Tighten the two fixing screws onto the cutter
flats with the hex keys supplied.
FITTING THE DRILL CHUCK SUPPLIED
To replace the arbor (A) with the drill chuck
supplied first remove the arbor.
To do this, using the spanners supplied, place
one spanner on the flats of the drill output
shaft.
Turn clockwise (as viewed from above) until
the spanner meets the dovetail slide.
Place the the second spanner on the flats of
the arbor, apply pressure, again clockwise as
viewed from above.
If possible the magnet can be used to hold
the machine whilst removing the arbor.
If the arbor is tight the spanner on the arbor
flats can be tapped with a soft mallet.
Once the arbor is unscrewed the arbor
support bracket (B) needs to be removed.
This is accomplished by removing the two
hexagon socket head cap screws.
To fit the drill chuck simply screw it into place
on the spindle nose.
A special left handed screw is provided to
hold the chuck if the spindle rotation is
reversed (PB32 Combi only)
Replacement of the arbor is a reversal of the
procedure above.

REVERSING OF THE HANDLES
The three handles (C) which raise and lower the drill unit
are attached to the pinion shaft (D).
These handles and the pinion shaft itself can be turned
around so the handles can be used on each side of the
machine. This is useful if access is limited on one side of
the machine because of the machines location.
The handles are normally mounted on the same side as the
controls, if they need to be reversed the following procedure
should be used.
First, the drill unit and its slide should either be supported or
put into its lowest position to prevent the risk of it falling
when the pinion is disengaged.
The hexagon head cap screw in the end of the pinion shaft
end cap (E) should be unscrewed.
The pinion shaft end cap can then be removed, the pinion
shaft and handle assembly can be withdrawn.
The pinion shaft and handle assembly can then be mounted
on the opposite side of the machine, taking care to ensure
the pinion gear teeth engage with the rack teeth.
The pinion shaft end cap and its hexagon head cap screw
should then be replaced and re-tightened.

The drill unit or “motor” of the PB32 is controlled by a twin
push button switch at the top of the control panel.
The green button is ON the red button is OFF.
The green button is flush with the surrounding bezel.
The red button is raised above the surrounding bezel.
This is to prevent inadvertent operation of the drill unit.
The motor will not operate unless the magnet is switched
ON first.
BEFORE staring the motor the security of the magnet
should be physically checked, if any movement is possible
this should be rectified BEFORE using the drill.
If motor control has an under-voltage relay, if the power is
interrupted the motor will stop and will not restart when the
power is resumed until the motor control is operated again.
The PB32 is a single speed drill unit with a nominal no-load speed of 550 rev/min.
The PB32 Combi is variable speed, but for the purposes of using annular cutters on mild
steel, the speed should be st to its maximum.
Under load the drill unit will regulate its speed depending on the load applied.
ie: a small cutter will run faster than a larger cutter (if the same feed rate is applied)
The PB32 has the optimum power / torque / spindle speed for HSS annular cutters in the
range Ø12mm to Ø 32mm, cutting EN10025 S235J steel or its equivalent.

MOTOR CONTROL PB32 COMBI FWD/REV
The PB32 Combi drill unit or “motor” is controlled by a three position rotary switch (K) at
the bottom of the PB32 Combi control panel.
The motor or FWD / OFF / REV switch should be in the OFF position before connecting
the power supply to the machine.
The magnet switch should be in the ON position and the security of the magnet should
always be physically checked BEFORE the spindle is started.
To start the spindle in its normal rotation the three position selector switch should be in
the FWD position.
To start the spindle in the opposite rotation the three position selector switch should be in
the REV position.
The FWD / OFF / REV switch should NEVER be switched from FWD to REV or REV to
FWD without waiting until the motor has stopped rotating. Failure to follow this instruction
will result in damage to either the motor or switchgear.
The motor speed control on the PB32 Combi is intended mainly for tapping operations.
For normal use with an annular cutter the speed should be set to maximum to allow
maximum power.
The motor speed control knob (K) allows speed to be reduced by turning counter
clockwise and increased by turning clockwise.
Reducing the speed significantly will reduce the power/torque available.

15 PB32 - Revised 120810
USING THE DRILL WITH ANNULAR CUTTERS
Insert the correct pilot pin for the cutter into the pilot pin hole through the shank of the
cutter.
Mount the cutter in the tool holder (arbor) of the machine as described in previous
chapters, ensuring the cutter is secure and correctly fitted.
Position the machine on the work piece ensuring the magnet is on a flat clean ferrous
surface and the work piece is not below the minimum recommended thickness.
Use the pilot pin to align the centre of the cutter to the desired hole position.
Switch on the magnet and physically check the machine is securely adhered to the work
piece.
Once in position, attach the safety strap, if the magnetic adhesion fails for some reason
the safety strap will reduce movement of the machine.
Apply cutting fluid through the small holes in the arbor, the arbor has a small reservoir for
coolant which is fed down through the central pin hole to the cutter. The use of cutting
fluid will enhance the quality of the cut and prolong the life of the cutter.
Lower the safety guard provided.
Switch on the drill motor, feed the cutter down by using the three handles provided.
Proceed with caution, apply pressure gradually until the cutter has formed a groove of
approx 3mm (1/8”). Once a groove is established the pressure can be increased.
DO NOT apply excessive pressure, if excessive pressure is required it is a sign the cutter
may be worn, continuing to use a worn or blunt cutter will result in damage to the drill
motor.
If the drill motor slows significantly under load ease off the downward pressure.
On deep holes it may be necessary to withdraw the cutter to remove swarf and to apply
more cutting fluid.
A cutter in good condition will need only moderate feed pressure and will produce
continuous chips or swarf. Broken chips or swarf indicate a cutter or material problem, so
care should be taken.
If excessive swarf builds up during the cut it may be necessary to withdraw the cutter to
remove the swarf, care should be taken as the swarf will be both hot and sharp.
As the cutter begins to break through the feed pressure should be reduced slightly.
When the cutter breaks through a slug of material at the centre of the cut will be ejected.
This will be both hot and sharp. Care should be taken when handling the slug.
Care should be taken that the ejection slug is safe and can not injure anyone in the
vicinity, the slug should be prevented from falling where possible.
16 PB32 - Revised 120810
TAPPING — PB32 COMBI ONLY
The PB32 Combi, in addition to drilling with annular cutters, is designed to allow the
tapping of screw threads.
The tapping capacity of the PB32 Combi is M6 to M12.
This machine has variable speed and both forward and reverse spindle rotation.
Magnetic based drills are normally used for cutting through holes with annular cutters,
the tapping facility of this drill is for tapping through holes.
If tapping of blind holes is required then an automatic reversing tapping chuck should be
used for best results.
The images below show the available Powerbor taps and holders, these have Powerbor
weldon shanks and fit directly into the 3/4” Weldon shank arbor of the machine.
COMBI DRILL/TAP - M6 - M10
(M12 With Annular Drill)
2-IN-1 DRILL TAP - M12
To tap a hole first set up the machine as for drilling with annular cutters in previous
chapters. Ensure the machine is secure before commencing any drilling operation.
Combi Drill/Tap
Drill the hole to the recommended tapping size for the thread to be cut.
Without disengaging the magnet replace the drill with the tap.
Set the spindle speed to the required tapping speed, apply tapping or cutting compound.
Start the drill spindle in the forward direction and feed the tap into the hole until it begins
to cut. Once cutting the tap will feed itself through, only gentle pressure on the feed
handles should be necessary.
Once the tap has threaded through the plate the drill should be stopped immediately.
The drill spindle should then be switched to reverse and the tap can be fed back out of
the hole.
17 PB32 - Revised 120810
TAPPING — PB32 COMBI ONLY (Cont.)
2 - IN - 1 Drill Tap
When using a 2 - IN - 1 Drill Tap, this type of tap is restricted to plate thicknesses of the
diameter of the tapping size. ie: M12 = 12mm plate. This is due to the length of the plain
portion of the shank after the threaded portion.
If the plate to be drilled is thicker than the diameter of the thread to be cut, the Combi
type drill and tap should be used.
Position the drill and ensure the security of the magnet on the work piece.
Set the spindle speed to the required speed, drill the hole with the drill portion of the
cutter, it may be necessary to slow the speed (depending on size) before tapping.
Always use tapping compound or cutting paste for best results and prolonged cutter life.
Allow the tap the feed through with little or no feed pressure, once the threaded section of
the tap is through the drill will stop feeding and just rotate.
Stop the spindle, switch to reverse, help the tap to begin feed up with very light upward
pressure on the feed handles.
Once the tap is out of the hole the machine can be removed.
IMPORTANT when tapping NEVER switch the machine from forward to reverse without
allowing the motor to stop first. Switching directly from foward to reverse can damage the
motor and switchgear.

The tapping speeds shown above are for guidance only, condition of the cutter and
specific material conditions will dictate actual speeds required.
OPTIONAL COOLANT SYSTEM
The arbor supplied with PB32 and PB32 Combi has an internal reservoir for coolant built
in.
If additional coolant capacity is required, an external coolant system which feeds through
the arbor is available.
This system must be specified at time of purchase, as the external coolant system can
not be retro fitted to existing machines.

MAINTENANCE
To keep this machine in a safe working condition regular certain maintenance is
required.
1. The gib strip on the dovetail slide must be adjusted to eliminate any free play.
2. The dovetail slides will need to be lubricated will oil periodically.
3. The magnetic base should be inspected for damage on its magnetic surface or for
any damage to the resin, any damage should be repaired before using the drill.
4. A monthly inspection of the carbon brushes is recommended, excessive wear could
lead to motor damage or malfunction.
REPLACING CARBON BRUSHES
The carbon brushes (M) can be removed by
simply unscrewing the brush cap (L).
The brush has a spring and metal cap
attached, simply withdraw the brush to
inspect or replace it.
When replacing the brush, slide it into the
brush holder, make sure the metal cap of
the brush seats in the recess on the brush
