‹
Weldon shank.
Connect the cooling lubricant system.
‹

NOTE
Observe the following instructions when drilling with core drills:
► Drilling with core drills does not require great effort. The dril-
ling process is not accelerated by higher pressure. The drill
wears faster and the machine can be overloaded.
► Use the high-performance BDS 5000 cutting oil in the coo-
ling lubricant system of the machine.
► The cooling lubricant system cannot be used when wor-
king overhead. In this case, use the high-performance ZHS
400 grease spray. Spray the drill on the inside and outside
before drilling. Repeat this procedure when drilling deeper
holes.
► Pay attention to the production of shavings. In the case of
larger drilling depths, break shaving regularly.
