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, the chip may break .
