The DRF System enables you, in conjunction with a soil sampling hammer, to use your rotary rig to dynamically sample through overburden and then go straight into rotary coring using one casing size for leaner drilling production so you can deliver an in-demand service for your customer. One rig one job with continuous liner samples for the full depth of the hole.
This new system comprises a specially designed drive head with integrated keyways for a stronger more robust coupling and easier head removal, drive collar, spacer rod, sample casing and drive shoe to provide 76, 86, 101, 116 and 131mm core samples.
Class in accordance with BS EN ISO 22475-1:2006 and Eurocode 7
