NOTE
Observe the following instructions when drilling with core drills:
► Drilling with core drills requires no great effort . The drilling
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 from CS Unitec .
► 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 .
