the diamond splinters sink into the substrate.
The wet diamond core drill bit becomes less
sharp. The cutting performance weakens and
the user increases the pressure on the wet
diamond core drill bit, which in turn increases
the effect. After drilling a few holes, the wet core
drill bit segments are "glazed" or they tear off
at the least resistance in the stone and the wet
diamond core drill bit must be replaced.
•
Sharpening the wet diamond core drill bit using
the BAIER professional whetstone (ID No.
15453) or a soft stone between drilling enables
sunken in diamonds to be re-released and the
wet diamond core drill bit is sharp again.
•
Water cooling of the core drill bit segments is
necessary to extend the life of the wet 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 wet diamond core
drill bit.
•
14 The wet diamond core drill bit should plunge
into the wall only after the working speed has
been reached – green LED (1) lights up.
NOTE
Speed electronics with LEDs are provided for the
BDB 817 only.
