...Drill Drill Collars Spiral Drill Collars The spiral cut 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 spiralling starts 22” from the bottom of the slip recess or 79” from the box end and ends 30” from the pin end. Adding spiralling to drill collars reduces the weight by approximately 4%.
