4. Switch on the magnet and verify that the drill is in the right position and that the
machine is pushed tight against the work piece;
5. If your machine is equipped with a lubrication system, put open the valve to release
the oil. If your machine does not have such a system, fill the holes of the spindle with
oil;
6. Switch the motor on at and allow it to run at the required speed;
7. Turn the arms to start drilling. Apply only a slight pressure when the annular cutter
touch the metal. Do not push the annular cutter with force into the metal;
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 the motor and
your annular cutter will be 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 oil supply when necessary, if your drill does not have a lubrication system,
stop drilling regularly, refill the holes of the spindle and continue drilling;
10. Apply less pressure when the drill cuts through the material. The slug will be pushed
out of the cutter by the pilot pin;
11. Turn the arms to put the motor in highest position and switch off the motor unit;
12. Remove the burrs, metal chips and clean the cutter and surface without getting
injuries.
Caution: The slug can be sharp and very hot!!
5.2 Twist drills
Use twist drills with 19.05 mm (3/4") Weldon shank. Align the flat faces on the cutter shank
with the screws in the spindle. Make sure the shank is entered fully and correctly. Fasten the
screws with the provided Allen key.
5.3 Step drills and countersinks
Use step drills for reaming or countersink drills for countersinking with 19.05 mm (3/4")
Weldon shank and follow the steps mentioned in the previous paragraphs.
