1.1 Application
The PRO 200-A ATEX is an air drilling machine designed to drill holes either with diameters
of 75–200 mm (2.95–7.87") to a depth of up to 100 mm (4") using annular cutters or with
diameters of 12–45 mm (0.47–1.77") to a depth of up to 100 mm (4") using twist drill bits.
In addition, it is capable to change the rotation direction to allow direct tapping or tapping
by using a tap chuck with axial compensation. The machine is ATEX II 2 G/D c IIC T6/T4
certified to allow working in explosive environments.
Magnets allow the drilling machine to be fixed to ferromagnetic surfaces with a force
that ensures operator safety and proper machine operation.
