AF Shallow Core System

(Patent N 01268480)



AF SHALLOW CORE SYSTEM is a continuous core drilling system for granular and cohesive rocks, specifically engineered for quick coring.


 AF SHALLOW CORE SYSTEM particularly suited when a continuous coring for detailed stratigraphy is needed and the use of a traditional drilling system is precluded by logistics or environ.




is the only one coring system allowing 100% sample retrieving even in saturated loose sands!



AF SHALLOW CORE SYSTEM allows 100% recovery of continuous + 30ft long core, with low geotechnical parameters alteration, for stratigraphic, paleontologic, chemical or granulometric analysis etc..



The use of a specially designed and engineered textile liner allows an easy handling and storing of the core even in absence of any dedicated container, furthermore, the core is retrieved just by gravity: no special tool required!







  • geognostics

  • pollution moitoring

  • stratigraphy

  • agropedology

  • palinology

  • hidrogeochemical studies etc...


AF SHALLOW CORE SYSTEM is composed by:

  • drilling string: ultra-light drilling pipes, coring bit, core sheathing head, sheath cartridges

  • gas hummer

  • recovery jack


Sheathing head:

maximum thickness, including enlarger ring, only 9 mm (outer radius minus core radius); just two parts easily assembled (sheath holder and coring bit). Fout head= 63 mm Core diameter= 44 mm
