4.2 Magnet base
By combining EUROBOOR permanent magnet technology and a pneumatic drilling unit, we have
created a tool that is capable of quickly and safely drilling on flat surfaces in potentially explosive
atmospheres. Permanent magnets allow for a more efficient field on thinner material, allowing more
consistent tip forces.
Make sure the magnetic drilling machine is placed on a smooth, clean, level and solid surface without
any objects or debris to guarantee maximum adhesion.
The workpiece must at least be 6 mm (1/4") thick for the magnet to stick and to drill safely. In case
the workpiece is between 3 mm (1/8") and 6 mm (1/4"), make sure to make a proper base to create
a good magnetic field as shown below.

Full saturation of the permanent magnet is reached with 15 mm steel.
When the electromagnet is not able to create a good enough magnetic field, this may be caused by
- Surface not being flat;
- Workpiece is not magnetisable (e.g. aluminium);
- Workpiece is coated or painted;
- Workpiece is not thick enough.
- Temperature of the workpiece, which should not exceed 80° C (176 °F)
Using the magnet:
1. Place and position the machine on the workpiece;
2. To activate the magnet, firmly grab the knob at the backend of the machine and rotate it
clockwise 180°;
3. To deactivate the magnet, rotate the knob counterclockwise by 180°.
