5. When fastening to solid concrete with a drop in anchor, a hole
must be drilled into the base material. A hammer drill should be
used as it will drill the best quality hole. Once the bit is chucked
into the hammer drill, the depth of the hole to be drilled can easily
be set by using the depth gauge on the drill or by wrapping the
bit with tape at the required depth. We recommend a drill depth
of 1-5/8” deep so that the anchor just sets down flush with the
surface. (Figure 5)
6. Before starting to drill the hole, it is important that eye and ear
protection are used. Make sure the hammer drill is in the hammer
mode and start drilling your hole. Continue drilling until the tape on
the bit or the drill gauge meets the base material- this means that
the required depth has been reached. (Figure 6)
