Detailed Product Description
Spiral drill collars are widely used because of their maintenance features. The special grooves decrease the volume of the contact between the well side and the pipe. It leads to the decrease of the tack of the pipe and to turning of the drill pipe string.
The weight of round drill collars will be reduced approximately 4-6% by spiral conversion.
