Product Description
Spiral drill collar is one kind of our product series. It's processed with three right-hand spiral grooves on the outer cylindrical surface of the circle drill collar, in order to reduce the contacting areas with well wall and revolution resistance. It can effectively keep the jamming of the drill tool from pressing badly. The weight of spiral drill collar is less 4% than the slick drill collar with the same specification. The shape on the two ends is similar to cylindrical drill collar. There are two types according to its spiral grooves: typeⅠand typeⅡ.
