The use of a shroEPTTor collar is needed when a RC hammer is utilized, to help direct the return air and cuttings up through the confront of the little bit.

A traditional DTH hammer is employed in conjunction with a cross-above sub positioned between the hammer and drill rod. The sample travels from the face of the bit up the outdoors of the hammer and into the cross-above sub.
The sub directs the sample up the cEPTTr of the dual wall rods and to the floor.
