Product Specification

Product Description

Drill collar is mainly used to provide bit weight to drill bit so that drill pipe is in tension. Especially drill collar can keep drill bit centralized and hole track by large rigidity. Spiral drill collar is used to reduce contact area with hole so as to avoid efficiently bit sticking from differential pressure. We have obtained the APE Spec 7, Spec **1, 5CT, 6D monogram right and certificate of ISO ***1:***0.
