DK22, DK32 and DK34 are diamond core drills which are operated only when fixed in a rig (2) (rig-
controlled).This core drill is only intended for professional use and may only be operated by trained
personnel. Proper use extends only to the drilling of rock, concrete masonry and asphalt.
By the addition of water through the diamond drill bit (3) via the ball valve (1a) the drilled material is
flushed away and the tool cooled (wet drilling). The drilling tool, the diamond drill bit (3), is a hollow drill
(tube) which is fitted with soldered-on or welded-on segments impregnated with diamonds.
The machine may not be used for a different purpose or with a different tool.
If necessary, the flushing water is extracted through a water collecting ring (4) by means of an all-purpose
suction unit.
ATTENTION: Avoid wet drilling upwards (overhead drilling). If it is indispensable use
absolutely a perfect, all right and functioning water-collecting ring.
