Tinius Olsen’s Core Case is for drilling concrete cores and to keep the surface clean and cool; it also allows the core drill to easily produce cores up to 100mm in diameter without the use of a frame and feed.

Water is fed into the jacket and flows through a manifold, into a drill spindle and continues to the inside of the diamond core bit. The water jacket surrounding the core barrel is flanged so that it can be clamped to the surface to be drilled with the supplied clamping pliers and anchors.

A rubber O-ring, fitted on this flange, seals the assembly against the concrete surface, enabling return flushing water containing the cuttings to be hosed away from the site.

Drill feed assembly is common to all models and makes the system adaptable to all core diameters with simple conversion kits. Core Case is a portable, self-contained system, easily carried by one person in a standard briefcase.
