Hilti metal expansion anchors M12 and M16 are usually suitable for use as anchors for diamond core
drilling equipment in uncracked concrete. Under certain conditions, however, it may be necessary
to use an alternative fastening method. Contact Hilti Technical Service if you have questions about
secure fastening.
1. Set an anchor that is suitable for the base material. Select the distance to suit the base plate used.

4. Screw the clamping nut on to the spindle but do not tighten it.
5. Use the leveling screws to level the base plate. Make sure that the leveling screws are firmly seated
against the surface.
6. Use a suitable open-end wrench to tighten the clamping nut on the clamping spindle.
7. Make sure that the diamond core drilling machine is secure.
5.2 Securing the drill stand by vacuum
WARNING
Risk of injury if pressure is not checked !
▶ Before and during drilling, check that the pressure gage pointer remains in the green zone.
In order to use the drill stand with anchor base plate, establish a secure, flat-on-flat connection between
vacuum base plate and anchor base plate. Screw the anchor base plate securely to the vacuum base
plate. Make sure that the core bit selected for use will not damage the vacuum base plate.
If you are going to drill horizontally, use additional means of securing the diamond core drilling machine
(e. g. chain secured to anchor).
Before positioning the drill stand, check that you have sufficient space for assembly and operation.
1. Turn all the leveling screws until they project approx. 5 mm underneath the base plate.
2. Connect the vacuum connector on the vacuum base plate to the vacuum pump.
3. Locate the center point of the hole to be drilled. Draw a line from the center of the hole to be drilled in
the direction in which the machine is to be positioned.
4. Make a mark on the line at the specified distance from the center of the hole to be drilled.
