Drilling with core drills
Proceed as follows when drilling with core drills:
For core drills with 19 mm Weldon shank, install the quick-
change drill chuck system (A).
For core drills with 32 mm Weldon shank, install the industrial
arbor (G).
Connect up the cooling lubricant system.
Install the appropriate ejector pin in the core drill and insert
the core drill into the tool mounting.
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 effort. 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.
