The  assembly  is  secured to the workbench by means of a base plate being provided  with  a  post clearing  the  whole  table area.

The motor  head finds itself at the end of the tilting arm and is apt to always move at right angles with respect to its working area.

The  motor  speed, the  tool  automatic lubrication and the depth control can be adjusted by means of a display placed on the cover of the electronic board case.




The working height of the machine can be increased by 160 mm. in order to thus be in a position to work at different heights.

Automatic Tap Lubrication


Inside the radial arm the cutting oil reservoir is located. This is used for lubricating the tool during the tapping operation. The lubrication time according to the metric size to be done is adjusted by means of one of the upper head buttons.


Depth control


By means of an internal systemr, the machine controls the vertical arm position (Axe Z) in mm. so that you can control at which desired depth you wish to tap.
