The HD16 is a hand-held core drill with a water cooled high frequency motor with water supply. The
HD16 can be used manually as well as in a stand (3) (drilling hand-held or by stand). It is suitable for
drilling rock, concrete and masonry.
The HD18 is a rig operated core drill without switch handle and thus cannot be used manually.
The material that is loosened by drilling is washed away by water provided through the diamond core bits
(4). The supply of water can be controlled by the ball valve (1a). At the same time, the tool is cooled (wet
drilling).
The boring tool (4) consists of a tube with an appropriate tool adapter G ½" , or 1 1/4" UNC, and with
soldered-on or welded-on diamond segments.
In case of wet drilling it is possible to suck up the water with a vacuum cleaner through a water-collecting
ring (5).
The machine may not be used for a different purpose or with a different tool.
ATTENTION: Avoid wet drilling upwards (overhead drilling). If it is indispensable use a
perfect, all right and functioning water-collecting ring.
