The drill is suitable for drilling work in metal.
Please see data sheet for performance data.
Insertion of core drills:
Clamp the core drill in the Keyless quick change arbor by moving the
sleeve upwards and inserting the correct drill together with the ejector
pin into the chuck. Turn the core drill a little in order to check that the
clamping jaw is engaged.
When clamping the core drills in standard industrial arbors
(ZIA 219 – 319 – 332 and direct arbor), both set screws are slightly
tightened on the clamping surface of the core drill.
Speed setting:
Both machine types are provided with a gear with four mechanical
gear stages and full-wave control electronics.
First, make the correct mechanical setting and then adjust the exact
speed by means of the electronic speed control.
