Tips & tricks
Check for reinforcement:
Heller hammer bits will stand up to hitting reinforcements. Despite this, it is still a good idea to check the wall structure with a detector before you start drilling and to drill masonry only wherever possible. Reinforcements are integrated into constructions for reasons of structural strength and shouldn't be cut if this can be avoided. If you can't avoid this for design reasons, you must consult a structural engineer before you start.
Check for piping and cable routing:
When you start drilling, it is a good idea to check the area for piping and cable routing.
Cables and pipes normally lead vertically up and down to the socket or fitting. For this reason, it is a good idea not to drill directly above or below fittings or sockets.
For through hole drilling you should always analyse the structure of the opposite side. Use a special detector for this purpose.
Grease the barrel
We recommend greasing the end of the bit shaft before inserting into the chuck.
This will extend the service life of your hammer drill.
Remove material residues
Before fitting a plug, you should always remove material residues from the drill hole to guarantee the best possible hold for the plug.
