9 Handling dry diamond core
drill bits
•
Always use and store dry diamond core drill
bits in accordance with the manufacturer's
instructions.
•
Too soft diamond segments:
f Dry diamond core drill bits wear too quickly
at very high removal rate.
Remedy: The material to be machined
requires dry diamond core drill bits with a
harder bond.
•
Too hard diamond segments:
f The diamond grains become blunt and do
not break out of the bond. The dry diamond
core drill bits no longer have any cutting
power.
Remedy: The material to be machined
requires dry diamond core drill bits with a
softer bond.
•
If extraction is not used during machining, the
dry diamond core drill bit rubs increasingly
against "soft" drill dust. The core bit segments
heat as a result, they become soft and the
diamond splinters sink into the substrate. The
dry diamond core drill bit becomes less sharp.
The cutting performance reduces and the user
increases the pressure on the dry diamond core
drill bit, which in turn increases the effect. After
drilling a few holes, the core bit segments are
"glazed" or they tear off at the least resistance in
the stone and the dry diamond core drill bit must
be replaced.
•
Sharpening the dry diamond core drill bit on the
BAIER professional whetstone (Id. No. 15453)
or on a soft stone between drilling enables
sunken in diamonds to be re-released and the
dry diamond core drill bit is sharp again.
•
It is necessary to cool the drill bit segments
through extraction to extend the life of the dry
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
formation of cracks. Before use, ensure that
there are no cracks in the dry diamond core drill
bit.
•
11 The dry diamond core drill bit should plunge
into the wall only after the working speed has
been reached – green LED (3) lights up.
•
After approx. 2 minutes of cutting time the
machine should be run with no load for
10 seconds, so that the dry diamond core drill
bit can cool.
