Casing for overburden drilling systems
Colcrete Eurodrill casings are manufactured to withstand the shock loading and torque produced when using DTH hammers with eccentric and concentric overburden drilling systems.
There are many Casing Advancement systems available on the market from a number of manufacturers. We are able to supply equipment compatible with most systems.
With such a wide range of overburden drilling systems now available, it is recommended that any new system should be checked with us to ensure correct starter length casing size, wall thickness and ID tolerances.
We can make hardened alloy steel casing shoes to order, and we can also take care of welding shoes and ring bit assemblies to casing when required.
Casing lengths and specifications can usually be produced to your specifications.
Listed below are the casing and shoe sizes for the most popular systems. Of course other sizes are available on request, and don’t forget, we can also supply the drill rods!
