Excore has a complete line of high performance surface set and impregnated reaming shells designed to cater to your drilling needs.

Keeps the overburden section of the hole from collapsing. Casings are available for the full range of drill string diameters, and are robust in construction to suit the most demanding of overburden drilling requirements.

The combination of diamonds and matrix determine the performance of an impregnated bit. The simultaneous erosion of the matrix and the diamonds make the bit self sharpening. The ideal combination of optimal peneration rate and wear resistance matched to achieve the ultimate in drilling economy. In most geological formations, impregnated bits are more economical to use than surface set bits and they provide additional benefits. Conventional bits are primarily used in shallow holes as the rod needs to be retieved with each core sample. Thin kerf bits provide a larger core size for the same diameter hole.

The compact surface double tube wireline core barrel uses a smaller, basic head assembly and is a predominant and extremely versatile core barrel configuration used in mineral exploration. The Compact core barrel is used in all but the most broken and friable ground conditions; it is designed for ease of use with drilling additives and loss control materials when required

Excore casing shoes are an impregnated V ring design and can be offered in standard or heavy duty.

Standard in Excore series head assembly, fluid indication system will give a signal when inner tube has landed in the locking coupling.

When encountering faults or other dry hole applications and it is necessary to maintain water column, the 3 different levels of spring hardness will be used at different depth and set to allow fluid passage at different pressure.

This valuable tool will improve production when the depth of overburden is high or it is difficult to reach rock formation only using a casing shoe. One overshot, casing shoe and tri-cone bit is needed to use this system.
