7.
Use the feed handle to lower the cutter to the workpiece, begin with relatively light pressure
until a groove is formed.
8.
Apply a regular pressure while drilling. The drilling performance does not improve by putting
more pressure on the tool. Too much pressure will overload and slow the motor and as a
result your annular cutter will become worn sooner.
A continuous, non-discoloured iron swarf is a sign of correct drilling speed and a well-cooled,
sharp cutter. Let the cutter do the job and give it time to cut the metal!!!
9.
Adjust the coolant/lubrication supply as necessary.
10.
As the cutter approaches break though, apply less pressure.
The slug will be ejected out of the cutter by the pilot pin. Take care to ensure the ejected slug
is contained and does not present a hazard
11.
Once the slug is ejected, with the cutter still rotating, reverse the feed handle back until the
output shaft is in its highest position and stop the motor unit.
12.
Remove any burrs, metal chips and clean the cutter and surface wearing PPE, safely.
13.
To remove the annular cutter, hold the cutter whilst releasing the two fixing screws, and pull
down the cutter.
After drilling the cutter can be hot, resulting in a tighter fitment inside the output shaft. If
this makes the cutter hard to remove, wait a few minutes for the cutter to cool down and try
again.
PROTECT YOUR HANDS FROM THE SHARP CUTTER!
Caution
: The ejected metal core piece drilled out can be sharp and very hot!!

release arbor.
1.
To fit the cutter, lift the
collar arrowed.
2.
Insert the cutter and rotate
until the flats of the cutter
align with the retainers in
the arbor.
3.
Release the collar it should
drop to its original position.
4.
Check cutter is secure
before use.
