Drilling with core drills
Proceed as follows when drilling with core drills:
 Install the MK3/19 mm Weldon industrial holder (A) and con-
nect up the cooling lubricant system.
 Install the appropriate ejector pin in the core drill and insert
the core into the MK3/19 mm Weldon industrial holder (A).
 Position the machine at the working location, align it and
switch on the magnetic clamps.
 Select the appropriate speed and switch on the machine.
NOTE
Observe the following instructions when drilling with core drills:
► Drilling with core drills requires no great e󰀨ort. The drill-
ing process is not accelerated by higher pressure. The drill
wears faster and the machine can be overloaded.
► Use the cooling lubricant system installed on the machine
with high-performance cutting oil BDS 5000.
► The cooling lubricant system cannot be used when working
overhead. In this case use the high-performance grease
spray ZHS 400. Spray the drill on the inside and outside
before drilling. Repeat this procedure when drilling deeper
holes.
► Pay attention to a regular chip discharge. With larger drilling
depths, break the chip.
