POLYCRYSTALLINE CORE BIDS

Polycrystalline core bids are mainly used to drill holes deepest than one linear meter. Polycrystalline core drills are suited to drill materials such as briques, tuff and sandstones.
As it is not possible to extract the core from the hole, the continuous coring makes the drilling possible by screwing gradually 500 mm extensions one to the other until the end of the drilling.
Wet or compressed air use, is possible.
Since it is a very techincal work, we advise you to contact one of our Diakom specialists that will be able to give you a dedicated and professional consultancy.
Upon request we can provide extractors in order to analyse  the materials composition and stabilisers to avoid that the core bid could bend the path during the drilling.
