The spiral drill collar is added to a drill collar to prevent the likelihood of differential wall-sticking by reducing wall contact between the drill collar and the wall of the hole. The box end of the spiral collar is left uncut from 79 inches from box shoulder and the pin end is left uncut 30 inches from the pin shoulder.

API relief groove pin and bore back box stress relief are available on request.

Thread roots are cold-worked to offer a greater resistance to fatigue.

All connections are phosphated to minimize galling during makeup and applied with thread storage compound.

Thread protectors are installed to ensure adequate joint protection during shipment.
