9 Handling Diamond Core Drill
Bits
•
Always use and store diamond core drill bits in
accordance with the manufacturer's instructions.
•
Too soft diamond segments:
f Diamond core drill bits wear too quickly at
very high removal rate.
Remedy: The material to be machined re-
quires diamond core drill bits with a hard-
er bond.
•
Too hard diamond segments:
f The diamond grains become blunt and do
not break out of the bond. The diamond core
drill bits no longer have any cutting power.
Remedy: The material to be machined re-
quires diamond core drill bits with a soft-
er bond.
•
If extraction is not used during machining, the
diamond core drill bit rubs increasingly against
"soft" drill dust. The core drill bit segments heat
as a result, they become soft and the diamond
splinters sink into the substrate. The diamond
core drill bit becomes less sharp. The cutting
performance reduces and the user increases
the pressure on the diamond core drill bit, which
in turn increases the effect. After drilling a few
holes, the core drill bit segments are "glazed" or
they tear off at the least resistance in the stone
and the diamond core drill bit must be replaced.

•
Sharpening the diamond core drill bit with a
sharpening plate or a soft stone between drilling
enables sunken in diamonds to be re-released
and the diamond core drill bit is sharp again.
•
It is necessary to cool the drill bit segments by
extraction to extend the life of the diamond core
drill bit and to keep the cutting speed high.
•
Excessive drilling pressure can cause material
fatigue in the base metal and therefore the for-
mation of cracks. Before use, ensure that there
are no cracks in the diamond core drill bit.
•
20 The diamond core drill bit should plunge into
the wall only after the working speed has been
reached – green LED (3) lights up.
